There are some limitations with the model exporter, but at least all map channels are exported
One thing that I think is not right is that the model is broken apart when multiple materials are applied. You will get a mesh for each material. Once I manage to support exports of parent/child (nested) models, I am worried you get too many subobjects...
I have written a doc on the issues and how to correct them, but it's only roughly 50% complete. Any feedback from experienced modellers is appreciated.
Let me know if you have problems with it with the software you use or have screwed up exports. The export code must be as good as can be before import is even considered, so the more you guys test the faster I can work on a solid import function.
