do us a favor, edit your first posts and use suggested
then do favor to yourself and start with something easier, like car or another not animated object with low polygon count
you will have more problems with cube rotation than you can handle now, so start learning with tutorials, then expand them, and after a half of year, you could do imports and animations
there is no other way, or you just give up on developing, because you take more than you can handle now
ok i inderstand that but i must do this job it s my project of end education
