Error during merging meshes from imported .glb

[Mercurio]

Hi there,
i’ve an error while attempting to merging different meshes of the same imported .glb object.
The .GLB object is composed by 20 different meshes, but when i use BABYLON.Mesh.MergeMeshes i got this error: Error: Cannot merge vertex data that do not have the same set of attributes

You can try on this PG: https://playground.babylonjs.com/#HBRF92#61
See line 140.

It’s clear that the mesh object has something wrong, but i can’t figure out how to fix it.
Any idea?

Thank’s!

Basically, you can only merge meshes who are compatible together meaning they need to have the same info for instance (position + normals + uv1).

In your case it looks like some might have different combinations so we can not merge them or we would need to invent missing datas.

looks like few meshes have a 2nd set of uvs and other don’t.
