No VRM found

Error message

No VRM found

What it means

clipFromVRMAnimation(vrm, animation) takes both parameters optional on purpose, but if vrm is undefined it warns 'No VRM found' and returns undefined — you cannot build an AnimationClip from a VRMAnimation without the target VRM rig. The animation parameter is then never even examined.

Solutions

1. Ensure the VRM is fully loaded (await the VRM loader) before creating the clip.
2. Check the model-load path for a silently swallowed error upstream.
3. Guard the call site and skip animation setup when vrm is absent.

Example fix

// before
const clip = await clipFromVRMAnimation(vrmRef.current, animation) // vrmRef.current may be undefined

// after
if (!vrmRef.current) return // model not ready; skip or await model load first
const clip = await clipFromVRMAnimation(vrmRef.current, animation)

if (!vrm) { /* model not loaded yet: skip or await */ }

function isLoadedVRM(v: VRMCore | undefined | null): v is VRMCore {
  return !!v
}

When it happens

Trigger: Calling clipFromVRMAnimation(undefined, anim) after the VRM model failed to load, is still loading, or the variable was never assigned; wiring animation loading before model loading and not awaiting the model.

Common situations: Race between model load and animation load in onMounted; a model-load failure swallowed earlier so undefined propagates; refactoring that renamed the vrm variable.
