@Ceciliabr That's interesting, I've been wondering for a while why some textures don't import with .obj files, and now I know! Can you recommend some specific software to do these conversions? I'm not sure what to search for.

On a related note, I also have trouble with .3ds files downloaded from the internet not importing textures, even with .png and .jpg texture files. I've read that you have to zip everything in one file, which I've tried, but it still doesn't work. Any tricks on how to make it work?

Thanks so much!
