I imported now all my platforms into blender, but now they're missing their textures and YouTube tutorials say, that I have to import texture files (which I don't have) into blender, too. I think it's just an unprofessional way to edit the texture of 200 different parts... My plans are to cut platforms and merge all parts together when I imported textures... If you have done something with platforms in blender, please tell me how you have done that!
