Reading the report

Every conversion produces a report: in the window while you work, and as Markdown through Copy report or Save report. Its first line names the package version and the source releases the readers were checked against; see Versions checked.

Severities

Heading	Meaning
Warnings	Converts, but not the way it worked before, or something could not be read.
Dropped	No Basis equivalent.
Approximated	Fitted onto a Basis setting that does not mean quite the same thing.
Mapped	Carried across as it was. Listed so the report is complete.

Entries with the same code are grouped, with a count and one example.

Codes

Every code the converter emits, by area. A few codes appear at more than one severity depending on the case; the usual one is given.

Source files

Code	Severity	Meaning
avatar.noPrefab	Warning	Nothing selected is linked to a prefab, so there is no file to read.
avatar.rootNotPrefab	Warning	The selected object is not linked to a prefab. Only the prefab instances beneath it were read.
source.sceneOnly	Warning	Components with missing scripts that exist only on the scene object, not in a prefab file. Apply them to the prefab in the project where their scripts are installed.
source.notText	Warning	The prefab file is stored in binary form and nothing in it can be read. Switch the project where its scripts are installed to Force Text, save the prefab there, and export again.
avatar.missing	Warning	The prefab file the selection points at does not exist.
avatar.notLoaded	Warning	The file did not load as a prefab.
source.severalPrefabs	Mapped	The avatar is built from several prefabs. Each was read from its own file.
source.overridesApplied	Mapped	Property overrides from prefab variants and nested prefab instances were applied before reading.
source.prefabVariant	Mapped	The avatar is a prefab variant, so the prefab it inherits from was read as well.
source.inheritedUnreadable	Warning	A prefab this one inherits from could not be read, so what it carries was not converted.
source.modelRead	Mapped	The prefab was saved from an imported .vrm without unpacking, so its components were read from that file.
source.notUnpacked	Warning	Nothing was found, and the prefab was saved from an imported model without unpacking. Unpack it completely and save it again.
source.editorOnlyTool	Mapped	Components of an editor-time authoring tool. They carry no runtime behaviour.
source.unknownScript	Warning	A component whose script this version does not recognise. Please report it.
source.vrcfury	Mapped	How many VRCFury components were read, by kind: toggles, full controllers, armature links, other.
vrcfury.togglesRebuilt	Mapped	How many VRCFury toggles became Vixxy controls. VRCFury does not run on a Basis build.
vrcfury.toggle.dropped	Dropped	A hold button, or a toggle with no menu item that an animator parameter drives. Not rebuilt.
vrcfury.toggle.animatorOnly	Approximated	The toggle also had a transition, a separate local state, a security lock or drove another parameter. The control switches its states directly.
vrcfury.exclusiveTag	Approximated	Toggles sharing an exclusive tag turned each other off. Vixxy controls are independent.
vrcfury.action.dropped	Dropped	Toggle actions a Vixxy control cannot express, by class: material swaps, animation clips, scale, and the rest.
vrcfury.action.unresolved	Warning	An action names an object, blendshape or renderer that is not in the prefab. That part was left out.
vrcfury.fullController.assetMissing	Warning	A Full Controller names a controller, menu or parameter asset that could not be read.
vrcfury.fullController.untraced	Dropped	A Full Controller's menu controls traced to no toggle layer in its FX controller.
vrcfury.armatureLink	Mapped	How many Armature Links are applied and how many clothing bones go under the avatar's.
vrcfury.armatureLink.unresolved	Warning	The link's target could not be found: the avatar has no humanoid rig, the bone or object is missing, or the clothing was scanned on its own.
vrcfury.armatureLink.auto	Approximated	A link in VRCFury's old Auto mode. The clothing's meshes decided whether the whole tree merges.
vrcfury.armatureLink.physBone	Approximated	Bones inside a PhysBone chain stay with the chain instead of going under their own avatar bone.
vrcfury.armatureLink.attached	Approximated	Linked bones carry renderers, which now follow the avatar bone and are no longer under the clothing's own object.
vrcfury.armatureLink.constraintRemoved	Mapped	Constraints on linked bones were left out, as VRCFury removes them.
apply.unpacked	Approximated	A prefab instance was unpacked so its bones could go under the avatar's. Unity allows no other way; undo restores it.
vrcfury.feature.unread	Dropped	Other VRCFury features, by class and count. None of them is read.
source.builtCopy	Warning	The avatar carries VRCFury's build markers: it is a copy VRCFury built, whose menus cannot be read. Convert the original.

Writing

Code	Severity	Meaning
apply.noTarget	Warning	Convert ran without a plan or a target.
apply.sourceUnresolved	Warning	A prefab is not where it was when scanned, so nothing read from it was written. Rescan.
apply.unresolved	Warning	A planned rig, constraint or head chop has no object in the target hierarchy and was skipped.
apply.descriptorUnresolved	Warning	The avatar descriptor has no object in the target hierarchy.
apply.vixxyUnresolved	Warning	A control switches an object that is not in the target hierarchy.
apply.motionUnresolved	Warning	A motion came from a prefab that moved since the scan.
vrm.runtimeRemoved	Mapped	UniVRM's runtime drivers were removed from the converted avatar. They rewrote expressions, spring bones and look-at every frame. Undo restores them.

PhysBones

Code	Severity	Meaning
physbone.unresolved	Warning	The PhysBone could not be tied to a transform and was skipped.
physbone.disabled	Mapped	The component was disabled and simulated nothing. No rig was written.
physbone.rootUnresolved	Warning	The Root Transform could not be resolved. The PhysBone was skipped.
physbone.radius.collisionRadius	Mapped	Radius became collision radius, with its curve.
physbone.radius.negative	Warning	A negative radius was clamped to 0 and collision left off.
physbone.gravity	Approximated	Gravity became the gravity multiplier, with its curve. PhysBone blends toward down; jiggle scales world gravity.
physbone.gravityFalloff.dropped	Dropped	Gravity Falloff has no equivalent, so gravity applies evenly.
physbone.pull.stiffness	Approximated	Pull, and Stiffness under Advanced, were fitted onto jiggle stiffness.
physbone.stiffnessCurve.dropped	Dropped	The stiffness curve was dropped. Jiggle stiffness took the pull curve.
physbone.spring.drag	Approximated	Spring was fitted onto drag.
physbone.springCurve.dropped	Dropped	Drag runs opposite to spring, so the curve would have inverted the falloff.
physbone.curves.domain	Approximated	Curves carried over. PhysBone samples them by bone index, jiggle by distance from the root.
physbone.immobile.ignoreRootMotion	Approximated	Immobile became ignore root motion, which cancels the root's translation only. A turning parent still swings the chain.
physbone.immobile.drift	Warning	Immobile 0.5 or more with a stiffness under 0.1. The chain will wander when its parent turns, because nothing brings it back. Raise the rig's stiffness.
physbone.immobileCurve.dropped	Dropped	The immobile curve was dropped. Ignore root motion is a single value.
physbone.immobileType.world	Approximated	Immobile Type World damps scene movement only. Ignore root motion also damps animated motion.
physbone.limitType.none	Mapped	No angle limit on either side.
physbone.limitType.angle	Mapped	The angle limit became a jiggle angle limit.
physbone.limitType.hinge	Approximated	The hinge angle became a cone. Nothing keeps the bone on one plane.
physbone.limitType.polar	Approximated	Separate pitch and yaw limits became one cone, using the wider angle.
physbone.limitType.tooWide	Approximated	The limit was wider than jiggle physics can express, so no limit was written rather than a tighter one.
physbone.limitRotation.dropped	Dropped	Limit Rotation was dropped. A jiggle limit is centred on the rest pose.
physbone.stretchMotion.stretch	Mapped	Stretch Motion became stretch, with its curve.
physbone.maxStretch.dropped	Dropped	Nothing bounds how far a bone may lengthen.
physbone.maxSquish.dropped	Dropped	Nothing bounds how far a bone may shorten.
physbone.endpointPosition.dropped	Dropped	Jiggle derives its own chain endpoint.
physbone.multiChildType.oneChild	Mapped	The root has one child and is simulated on both sides. Multi Child Type does not apply.
physbone.multiChildType.ignore	Mapped	Multi Child Type Ignore became a motionless root.
physbone.multiChildType.ignoreBranches	Approximated	Bones below the root with several children stay still in VRChat under Ignore. Jiggle swings them.
physbone.multiChildType.blended	Approximated	A shared root moved by its chains cannot be expressed, so the root was left motionless.
physbone.allowCollision.off	Approximated	Allow Collision off excluded other players' hands. Basis registers every avatar's hands, arms and feet as global colliders and a rig cannot opt out. The listed colliders still apply.
physbone.allowGrabbing.filtered	Approximated	Allow Grabbing was decided per player. Jiggle grabs for everyone or no one.
physbone.allowCollision.filtered	Approximated	Allow Collision was decided per player. Basis's global colliders cannot be excluded per rig.
physbone.allowGrabbing	Mapped	Grabbing kept its setting. Radius 0 is not grabbable in VRChat and locks the rig.
physbone.allowPosing.dropped	Dropped	Jiggle bones spring back when released.
physbone.snapToHand.dropped	Dropped	No equivalent.
physbone.isAnimated	Mapped	The rest pose followed animation. Jiggle always does.
physbone.parameter.dropped	Dropped	The animator parameter prefix has nothing to feed on Basis.
mapping.clamped	Warning	A fitted value fell outside its range and was clamped.

Dynamic Bone

Code	Severity	Meaning
dynamicbone.unresolved	Warning	The component could not be tied to a transform and was skipped.
dynamicbone.disabled	Mapped	The component was disabled and simulated nothing. No rig was written.
dynamicbone.noRoot	Warning	The component names no root, or has Blend Weight 0, and simulates nothing. No rig was written.
dynamicbone.rootUnresolved	Warning	A root could not be resolved. That chain was skipped.
dynamicbone.multipleRoots	Mapped	The component drives several chains. Each became its own rig with the same settings.
dynamicbone.radius.collisionRadius	Mapped	Radius became collision radius, with its curve.
dynamicbone.radius.zero	Approximated	Radius 0 with colliders. Dynamic Bone collides points; jiggle needs a radius, so 0.01 was written.
dynamicbone.damping.drag	Mapped	Damping became drag and air drag, with its curve.
dynamicbone.elasticity.stiffness	Approximated	Elasticity became stiffness by its square root; both are a per-tick fraction toward the pose.
dynamicbone.stiffness.angleLimit	Approximated	Stiffness caps deviation at 2·asin(1−s) degrees and became an angle limit of that angle.
dynamicbone.stiffness.tooWide	Approximated	The cap is wider than 90 degrees. No angle limit was written.
dynamicbone.stiffnessCurve.dropped	Dropped	The angle limit does not follow the stiffness curve.
dynamicbone.blendWeight	Approximated	Blend Weight below 1 stiffens the chain toward rigid. Folded into the angle limit.
dynamicbone.updateRate	Approximated	Update Rate other than 60 scales elasticity. Folded into stiffness.
dynamicbone.inert.ignoreRootMotion	Mapped	Inert became ignore root motion, measured at the rig root instead of the component.
dynamicbone.inertCurve.dropped	Dropped	Ignore root motion is one value per rig.
dynamicbone.gravity	Approximated	Dynamic Bone gravity is per tick without a time step and cancelled at rest. The preset's gravity was kept.
dynamicbone.force.gravity	Approximated	A force straight down with no gravity became a gravity multiplier, from 60 ticks a second.
dynamicbone.force.dropped	Dropped	A constant force has no equivalent.
dynamicbone.endpoint.dropped	Dropped	End length other than 1, or an end offset. Jiggle's own tip matches End Length 1.
dynamicbone.freezeAxis.dropped	Dropped	Nothing flattens a chain's motion onto a plane.
dynamicbone.friction.dropped	Dropped	Friction after touching a collider is not modelled apart from drag.

VRM spring bones

Code	Severity	Meaning
vrm.unresolved	Warning	A chain could not be tied to a bone and was skipped.
vrm.noJoints	Warning	A chain named no joints.
vrm.drag	Mapped	Drag force became drag, on the same scale.
vrm.radius	Mapped	Joint radius became collision radius, both in metres.
vrm.stiffness	Approximated	Stiffness force, which has no upper bound, was fitted onto jiggle stiffness.
vrm.stiffness.clamped	Approximated	A stiffness force above 1 was written as fully stiff.
vrm.gravity	Approximated	Gravity power became the gravity multiplier. VRM adds a per-step force; jiggle scales world gravity.
vrm.gravity.direction	Approximated	Gravity did not point straight down. Only the vertical part was kept.
vrm.angleLimit.cone	Approximated	A cone limit became a jiggle angle limit, capped at 90 degrees.
vrm.angleLimit.dropped	Dropped	A hinge or spherical limit has no jiggle shape.
vrm.center	Approximated	The chain named a centre transform. The rig ignores root motion fully, measured at its root bone.
vrm.springBone.disabled	Mapped	A VRMSpringBone was disabled and simulated nothing. No rig was written.
vrm.branchesExcluded	Mapped	Bones under the chain that the spring did not name were excluded, so they stay still.

Colliders

Code	Severity	Meaning
collider.limit	Warning	More colliders were referenced than a jiggle rig holds. The extras were dropped.
physics.excludedRoot	Approximated	The root bone was in its own ignore list. The rig keeps the root motionless instead.
collider.disabled	Mapped	The collider component was disabled. Rigs that list it get nothing, as on the source.
collider.transform.unresolved	Warning	A collider could not be tied to a transform. Rigs referencing it do not collide with it.
physics.collider.unresolved	Warning	A referenced collider or collider group was not in the file.
physics.excludedTransform.unresolved	Warning	An excluded transform could not be resolved.
collider.radius.negative	Warning	A negative radius was clamped to 0.
collider.global.dropped	Dropped	The collider was marked global, for other avatars' bones. Basis offers only hands, arms and feet to others, so this one stays local.
collider.insideBounds.dropped	Dropped	The collider kept bones inside it. Jiggle colliders only push bones out.
collider.bonesAsSpheres.dropped	Dropped	Bones As Spheres has no equivalent.
collider.capsuleRotation.snapped	Approximated	The capsule was rotated off an axis and was snapped to the nearest one.
collider.taper.dropped	Approximated	A Dynamic Bone capsule with two radii. One radius was used for the whole length.
collider.planeRotation.dropped	Dropped	A VRChat plane collider was rotated away from its transform's Y axis. It now faces Y.
collider.planeAxis.dropped	Dropped	A Dynamic Bone plane collider faced its X or Z axis. It now faces Y.
vrm.collider.capsuleSnapped	Approximated	A VRM capsule ran off an axis and was snapped to the nearest one.
vrm.collider.inside	Dropped	A VRM collider held bones inside its shape. It now pushes the opposite way.
vrm.collider.planeNormal	Dropped	A VRM plane collider's normal pointed away from its transform's Y axis. It now faces Y.

Constraints

Code	Severity	Meaning
constraint.unresolved	Warning	The constraint could not be tied to a transform and was skipped.
constraint.disabled	Mapped	The component was disabled and drove nothing. None was written.
constraint.locked	Mapped	Locked was off. VRChat ignores that in play, so the Basis constraint is locked.
constraint.retargeted	Approximated	The constraint drove another transform. It was written onto the transform it drives.
constraint.noSources	Warning	The constraint has no sources. It was created anyway.
constraint.source.empty	Warning	A source slot had no transform and was dropped.
constraint.source.unresolved	Warning	A source could not be resolved and was dropped.
constraint.source.overflow	Warning	Sources past the sixteenth sit in an overflow list that is not read yet.
constraint.source.weight.normalized	Approximated	A lone source below full weight follows fully on Basis, which normalises source weights.
constraint.worldUp.none	Approximated	World Up Type None leaves roll free in VRChat. Basis uses the scene's up.
constraint.weight.clamped	Warning	The weight was outside 0 to 1 and was clamped.
constraint.solveInLocalSpace.dropped	Dropped	Basis constraints solve in world space.
constraint.freezeToWorld.dropped	Dropped	No equivalent.
vrm.constraint.rotation	Approximated	A VRM rotation constraint copies a delta from rest. A Basis one follows the rotation itself, offset so the authored pose holds at rest.
vrm.constraint.aim	Approximated	A VRM aim constraint states no up direction, so the scene's up is used.
vrm.constraint.roll	Approximated	Nothing in Basis copies rotation about one axis, so this became a rotation constraint limited to it.
vrm.constraint.noSource	Warning	The constraint names no source. It was created anyway.

Avatar descriptor

Code	Severity	Meaning
descriptor.unresolved	Warning	The descriptor could not be tied to a transform and was skipped.
descriptor.noSource	Mapped	A humanoid rig without a descriptor. An empty Basis Avatar was added.
descriptor.autoSetup	Mapped	The animator, human scale, renderer list and mouth position are left for Basis to fill in when its inspector is first opened.
descriptor.visemes	Mapped	All fifteen visemes carried across, position for position.
descriptor.visemes.count	Warning	Fewer than fifteen viseme blendshapes were listed. The missing ones are unset.
descriptor.visemeMesh.missing	Warning	Lip sync was set to blendshapes with no mesh assigned.
descriptor.visemesUnset	Warning	Nothing named the visemes or blink. Assign them on the Basis Avatar by hand.
descriptor.lipSync.unsupported	Dropped	Lip sync was not blendshape based. Basis drives visemes from blendshapes only.
descriptor.eyeLook.disabled	Mapped	Eye Look was disabled, so blink is unset.
descriptor.eyelids.none	Mapped	No eyelid setup or no blink shape chosen, so blink is unset.
descriptor.eyelids.bones	Dropped	Eyelids were driven by bones. Basis blinks with a blendshape.
descriptor.eyelids.lookUpDown	Dropped	The looking up and down eyelid shapes have no equivalent.
descriptor.viewPosition.sideways	Dropped	The sideways part of the view position. Basis stores height and forward offset.
descriptor.animationLayers	Dropped	Custom animation layers were assigned. Basis has no playable layers.
descriptor.expressionsMenu	Dropped	The expression menu as a structure. Its toggles are rebuilt as Vixxy controls; see the menu codes.
descriptor.expressionParameters	Dropped	Expression parameters as a list. Vixxy controls carry their own state.
headChop.disabled	Mapped	The component was disabled and hid nothing. None was written.
headChop.head.ignored	Dropped	An entry named the humanoid Head. Basis scales the Head itself and ignores such entries.
headChop.condition.dropped	Approximated	A head chop bone was scaled away only in VR or only on desktop. Basis scales it away in both.
headChop.target.unresolved	Warning	A head chop bone could not be resolved and was dropped.
contacts.dropped	Dropped	VRChat contacts were found. Basis has no contact system.
raycast.dropped	Dropped	VRChat raycast components were found. Basis has nothing that fires a ray into animator parameters.
vrchat.buildSettings	Mapped	Per-platform overrides or impostor settings. They instruct VRChat's uploader and carry no behaviour.

Menu toggles

Code	Severity	Meaning
expressions.menu	Dropped	The menu's contents, counted by kind. Toggles and radials are rebuilt; the rest is not.
expressions.parameters	Dropped	Expression parameters were declared. There is no parameter list to recreate.
expressions.puppets	Dropped	Two-axis and four-axis puppets. Each drives two parameters at once.
expressions.togglesResolved	Mapped	How many animator layers were traced from the menu and how many became controls.
expressions.assetMissing	Warning	A menu or parameter asset the descriptor names is not in the project. A build tool's output under Packages/ is left out of a unitypackage export; copy that folder with its .meta files.
expressions.assetNotText	Warning	The menu or parameters sit in a file stored in binary form. VRCFury saves a built copy's menus that way, and only its own project can save the file again.
expressions.assetUnread	Warning	The file is text but holds no menu or parameters at the file id the descriptor names.
vixxy.rebuilt	Mapped	The count of menu toggles rebuilt as Vixxy controls, each with a menu item.
vixxy.notSimple	Dropped	The toggle animates over time or drives something a Vixxy control cannot hold.
vixxy.nothingToSwitch	Dropped	The toggle switched nothing that exists on this avatar.
vixxy.values.normalized	Mapped	A two-state control used a value other than 1. It was written as 0 and 1 so Basis presents a toggle.
vixxy.commsMissing	Warning	No HVR Avatar Comms on the avatar. Vixxy controls initialise through it; add the HVR.Networking prefab.
vixxy.puppetEnds	Approximated	A radial puppet blended through motions between its ends. A slider interpolates in a straight line.
vixxy.builtinGuard	Approximated	The layer also waited on a VRChat parameter such as IsLocal. The control switches whenever it is used.
vixxy.materialBlock	Approximated	The control sets material properties on a renderer with several materials. Vixxy sets them per renderer, so all are affected.
vixxy.targetMissing	Warning	The control switches an object that is not in this avatar. That object was left out.
vixxy.componentSwitch	Mapped	The toggle switches PhysBones or renderers on or off. The control drives their jiggle rigs and renderers.
vixxy.componentSwitch.dropped	Dropped	The toggle switches a component that is not a converted PhysBone or a renderer. That switch was left out.
vixxy.rootActivation	Warning	The control switches the avatar root, which Vixxy refuses. That object was left out.
vixxy.overlap	Warning	Two controls set the same object, blendshape or property. The control used last wins on Basis.
fx.layersUnread	Dropped	FX layers nothing read, by name. Only menu-steered layers and layers that play on their own are read.
fx.controllerMissing	Warning	The FX controller the descriptor names is not in the project, so nothing was traced. Same cause and fix as expressions.assetMissing.
vixxy.rendererMissing	Warning	The control sets a renderer or blendshape that is not in this avatar.
modularAvatar.hierarchy	Mapped	Modular Avatar components that rearrange the hierarchy or meshes. Left to Modular Avatar, which applies them at Basis build time when installed with the Basis NDMF platform.
modularAvatar.menus	Dropped	Modular Avatar menu and animator components. See Modular Avatar.
modularAvatar.togglesRebuilt	Mapped	How many Modular Avatar menu toggles became Vixxy controls.
modularAvatar.vrchatOnly	Dropped	Modular Avatar components that act on VRChat's own systems.

Authored motion

Code	Severity	Meaning
motion.baked	Mapped	An animator layer that plays on its own was rebuilt as authored motion.
motion.switched	Mapped	A menu toggle animated over time, so it was rebuilt as a motion the control switches on.
motion.notLooping	Mapped	The clip was not authored to loop. It plays once and holds its last frame.
motion.motionTime	Dropped	A state scrubbed by a parameter through motion time. Rebuild it as a slider by hand.
motion.notRotation	Dropped	A layer playing on its own animates something other than rotation, which a baked motion cannot hold.
motion.rotationOnly	Dropped	The layer also animates something other than rotation, which a baked motion clip cannot hold.
motion.noFolder	Warning	There was nowhere inside the project to write the baked clip, so no motion was written.
motion.nothingToBake	Warning	The clip turns nothing that exists on this avatar.
motion.pathMissing	Warning	The clip turns an object that is not under the avatar root. That part was not baked.

VRM expressions, face and metadata

Code	Severity	Meaning
vrm.objectUnreadable	Warning	The expressions, licence and eye offset are inside the .vrm and could not be read. Press "Extract Meta And Expressions" in the file's import settings.
vrm.licence	Mapped	What the licence says: title, author and who may wear the avatar.
vrm.licence.restricted	Warning	The licence forbids changing the avatar, or limits who may wear it.
vrm.expressionsRebuilt	Mapped	The expressions became one Vixxy selector named Expression: Neutral, then one choice each.
vrm.expressionsDriven	Dropped	Viseme, blink and look-at expressions were left to Basis, which drives those itself.
vrm.expression.materialValues	Mapped	An expression's material changes were written on the renderers that use the materials it names.
vrm.expression.materials	Dropped	An expression changes a material no renderer on the avatar uses.
vrm.expression.materialShared	Dropped	The material shares its renderer with others. Vixxy sets a property per renderer, so that part was left out.
vrm.expression.continuous	Approximated	Expressions VRM lets the wearer apply at any strength. A choice is all or nothing.
vrm.expression.override	Dropped	The expression blocks or attenuates blink, gaze or lip sync while worn. Basis keeps those running.
vrm.expression.shapeMissing	Warning	The expression names blendshapes that are not on the mesh. The mesh changed after it was authored.
vrm.visemes	Approximated	The vowel expressions filled five of the fifteen visemes. VRM names no consonants.
vrm.visemeCompound	Dropped	A vowel expression moves several blendshapes. A viseme names one, so it was left unset.
vrm.visemeMeshSplit	Dropped	Vowels sit on more than one renderer. Basis reads all fifteen from one.
vrm.blink	Mapped	Blink was taken from the avatar's own blink expression.
vrm.eyePosition	Mapped	The eye offset became the Basis eye position.
vrm.eyePosition.noRig	Warning	The avatar states an eye offset, but the rig is not humanoid with a head mapped.
vrm.firstPerson	Dropped	Renderers marked to hide from the wearer. Basis hides the head bone instead.
vrm.lookAt	Dropped	VRM 0.x look-at components. Basis drives gaze from the eye bones itself.
vrm.lookAt.expression	Dropped	The avatar aims its eyes with expressions, not eye bones, so its eyes do not follow gaze.
vrm.lookAt.range	Dropped	The avatar limits how far its eye bones turn. Basis turns eyes up to 25 degrees for every avatar.

Rig

Code	Severity	Meaning
rig.noAnimator	Warning	No Animator with an avatar. Set the model's Animation Type to Humanoid.
rig.notHumanoid	Warning	The rig is not a valid humanoid.
rig.missingBones	Warning	Bones the Basis validator requires are missing from the humanoid mapping, Chest and Neck included.
rig.bonesComplete	Mapped	Every bone the Basis validator requires is mapped.
rig.recommendedBones	Warning	A shoulder is unmapped. Basis places it from a fallback table and its validator warns.
rig.eyesMapped	Mapped	Both eye bones are mapped.
rig.eyesMissing	Warning	One or both eye bones are unmapped. Basis calibrates gaze from both.
rig.jawMapped	Warning	A Jaw bone is mapped. Basis does not drive it, and the window offers to clear it.
rig.twistBones	Mapped	How many arm bones have a twist child Basis will pick up.
rig.twistBonesAbsent	Mapped	Arm bones without a twist child. Basis applies no twist there.

The rig section

The report also checks the humanoid rig against Basis's IK: bone mapping, eye bones, twist bone names, and a mapped Jaw bone. These are model import settings; the window offers to clear the Jaw. See Rig check.
