@Eitan Traurig (EitanSomething) If you want to do some triaging, please do it properly. this is not even the proper projects at all.

@Julian (MotoFckr9k) not sure how you even get any transparency in that file? Your texture alpha channel is not linked to the alpha input of the shader node... Once this is done here I do get proper transparency on re-importing FBX file.
