May I ask what is the difference between absolute coordinates in mesh and regular coordinates in babylonjs

[HiGreg]

Ahh. You’re right. There’s absolutePosition, but not vertex data. See this post for getting absolute vertexdata:

@splash27

BABYLON.VertexData.ExtractFromMesh(box).clone().transform(box.getWorldMatrix());

Note there is also a “forceCopy” option in Extract that might help avoid the .clone(), but I’m not sure.
