Materials don't export with mesh

[ssenpsl]

I'm a newb with this program looking to save a lot of time in modeling by using this to get me close and then finish it up (hair, clothes, etc) in Maya. I've successfully made my character but when I export her in either fbx or obj the textures folder is empty. Anybody have an idea of what I might be doing wrong? One time out of 4 trial characters the textures appeared but now I can't get it to do it again. Please help.

Well, I figured out how to go in and copy the files that it would have used for the materials so it's a non-issue now. Loving the program, can't wait to see the additional options coming in the future.
