Starting from version 133 normal map creates artifacts on my scene with the GLTF model with SkinnedMesh, with morph targets and MeshPhysical material. Interesting fact that on version 135 it looks correct, and from 136+ (including the latest at this moment 156.1) with artifacts again. Can somebody tell me what can cause this and how I can fix it? The only thing I changed in the setup during testing is the three.js version.
Have you tried running BufferGeometry.computeTangents on the geometry of the skinned mesh? There were a couple of threads on this topic in the past few months that address a couple of different causes of this issue and fixes for each, ill try to dig them up if the above doesn’t solve…
where did you export the model from was it Blender? any chance you can make a minimal live reproduction in codepen / js fiddle / codesandbox and or share the model here?
