Toolbag model preview error

Doomathon

Hi, I am making an AK-47 and using Ddo2 with Skyshop to preview the model. It worked fine in TB2 before, but the preview window in Skyshop only renders half the triangles it seems (see screenshot). I was wondering if this is a Ddo2 issue, or a specific map issue maybe? My video card is fully updated.

I appreciate the assistance!
