so i made my map model in c4d now i have both a c4d file and a .3ds file. when i open them both in cinema 4D they look fine, but whenever i import the .3ds into 3ds max it looks all screwed up and it is untextured. what is the best way, straightfoward, to get the map model i made in c4d into 3ds and keep its quality and remain textured?
