Hello
I used the collider actor to move the iMeshWrapper object and thus all
of its children iMeshWrapper objects.
But as I told you. If I load on of those six mesh objects that face the
problem it is suddenly impossible to move the iMeshWrapper by the
collider actor.
If I don't load any of those six mesh objects then there is no problem
and I can move the iMeshWrapper.
So if I now use the iMovable of iMeshWrapper to move mtbWrapper then
there is no collision detection any more.
And I guess I need a collision detection in order to slide the mesh on
an uneven ground.
Was that clear enough?
I know my english is not the best :/
