[#7789] 3DS Import , Mesh not correct since Blender 2.44
There is a problem importing 3ds files where I cant find a way to check if the
transforms are applied to the vertex locations or not.
Since 2.44 I made the importer assume they were not since you can manually
remove transformations, but not reverse.
Nevertheless most 3ds files have the matrix applied, better not give a bad
import by default.
Did some research and other 3ds importers (lib3ds for eg), have the same
problem and just assume the transformations applied.
3dsMax imports both correctly so there must be a way to tell but I could not
link it to the 3ds version or other mesh options.
Added an option to workaround this problem in rare cases where its needed.
- KX_GameObject.cpp & KX_Scene.cpp, clear the dict before removing the
reference in case there is a circular reference.
