steps to reproduce (it's funny, i thought the first time i installed it worked...)
1) make install
2) choose car: select eg ferrari spider
3) ustunts exits with "Error: cars/ferrarispider/wheel.glb does not contain any data"
seems that the permissions on several cars subdirs is set wrong?
drwx------ 3 root root 216 Aug 9 11:47 ferrarispider
drwxr-xr-x 3 root root 216 Aug 9 11:47 ferrarispider
this happens to some other car-dirs as well: diablo, ferrarif40, jeep, porsche911, porsche928, subaruimpreza, tford...
it is correct on f1 and lego, though.
can anyone approve this?
