Hi!
Yes, you are right that mtbWrapper is the type iMeshWrapper!
Well, moving mtbWrapper by MovePosition and SetPosition of the iMovable
of mtbWrapper both work with all of the mesh objects as children.
But in that case I unfortunately loose the functionality that the
collider actor represents.
I don't catch the meaning of why it didn't work with moving the collider
actor.
Any idea?
