I'm never wasting my time trying to help others... the comment/uncomment bug is weird !
ok, if you need help, don"t hesitate, 3D rotations are not always easy to fix for such a project. just a last thing to try : use values like 90.001 (or 90,0 180,0, 180,001 instead of 90, in order not to have an integer). Just give it a try, I remember that I had such a problem one time I fixed that way... cheers
