I added some objects like cube, sphere and a cylinder on different positions with different rotations.
Then exported it as an *.obj file.
The problem here is, that the transformations are not included in the *.obj file.
I read this:
Blender Manual latest - Wavefront OBJ
There is no support for mesh vertex colors, armatures, animation, lights, cameras, empty objects, parenting, or transformations.
Ok. No transformations are exported. But is there a way to do that? A little trick that helps me to get the positions and rotations of the objects?
