Got a light into the game now.

I can't edit the shape or reassign the texture in the Map editor anymore like I was used to do when importing shapes before.
It is like the reimported item is fixed (kind of read-only).
Looks like I have to create the mesh geometry and the texturing properly in Blender already before the initial import...
And if I try the item editor, Maniaplanet absolutely wants me to save a crystal...
