Mesh.GetVertex (Get X Y Z)

Mesh.SetRotation Mesh.GetRotation.x, Mesh.GetRotation.y + 0.1, Mesh.GetRotation.z

Mesh.update

Mesh.GetVertex (Get X Y Z)

There is no change

It's not a bug

GetVertex returns vertex position in local space.

SetRotation only changes the matrix of the mesh.

If you want the rotation to have an effect on the vertices, you have to multiply the vector from GetVertex by the mesh matrix (mesh.GetMatrix)
