[Katinor]

Same issue as both above.
UniVRM: v0.118.0
Unity version: 2021.3.35f1
Windows version: 11

This is also happened in 2021.3 LTS, which is mentioned as required version.

[Pacmard]

Having same issue on v0.119, I guess its a subject to be fixed in 0.120? Any workaround for now?

[ousttrue]

Thank you for your report

at Assets/UniGLTF/Runtime/MeshUtility/MeshAttachInfo.cs:23

Mesh.bindposes = Bones.Select(x => x.worldToLocalMatrix * dst.transform.localToWorldMatrix).ToArray();

Has the gameobject used for skinning been deleted?

workaround

Please try disable instead of remove.

at Assets/VRM10/Runtime/IO/Model/ModelExporter.cs:306

skin.Joints = skinnedMeshRenderer.bones.Select(x => nodes[x.gameObject]).ToList();

Has the gameobject used for skinning been deleted?

workaround

Please try disable instead of remove.

[Katinor]

Tested again.
Same issue in v.0.119.0
Unity version: 2022.3.6f1

Exporting VRM by using object imported from VRM was fine. Issues above are only when I make VRM from first.

Deleting Skinned Mesh Renderer didn't affect.
It caused an error when I deleted bones (GameObjects under armature).

v.0.112.0 didn't have this issue.

Using several assets is normal during making an avatar, and deleting GameObjects with Renderer or under armature happens often for optimization and production convenience because not all components are necessary. Please reconsider this issue.

I was performing testing on the unedited avatar prefab, so nothing was disabled or deleted, hence I don't know where this comes from.

Using some older versions works just fine

I'm having the exact same error on a fresh prefab as well.

why should it matter anyways? shouldn't it be able to see that some reference is missing and ignore it like any other unity exporter tool, VRchat's SDK does for example. I may try to edit the code myself and see what I can come up with, but it's been years since I've done C#, so don't wait on me.
