I’ve had this problem for years now across many versions of sketchup and 3ds max, so I’m guessing it’s just systemic, but most of the time when I download a sketchup model and import it into 3ds max, the textures are about 50% destroyed. As in, you can’t even fix them. The geo’s UVs are broken.
I’ve tried exporting to collada file and that’s about the same.
I will say that these days I’m having to re-save the skp file to a v8 because of the issue with importing 2013+ files into 3ds max (my version of 3ds max is 2015) so not sure if it’s been resolved in newer versions of either software.
