[Solved]Why cant I export materials while a simple cube can?

[TheOwl]

If I just create a simple cube and put a different color for each face and export as an OBJ, the exported model contains all of the 6 materials as you can see below.

Now if I create a complicated model. The materials exported is only one! I need to export all of the materials I made, is there something missing or this is a limitation in SU?

I got it. See this:

Since that link doesn't directly point to your answer and someone else searching here may want to know, the materials don't appear because you painted them onto the back faces in your second example. The OBJ export only shows materials on the front faces.
