Custom model not exporting properly

[MissingTexture]

So I worked on a model for a CW Ryloth map I am doing, and it looks fine in XSI:

When I export it, then bring it into SWBFmshviewer, it ends up like this:

I then import it in another XSI window and only this is there:

What happened exactly and how can I fix it, without having to make a new model & texture from scratch again?

Try my new meshviewer. The old one can not triangulate as far as I know. If my displays it correctly, you just need to triangulate the mesh

Thanks Anakin, I just needed to triangulate the polymesh. Didn't know it was necessary for the model to be triangulated

.msh supports multiedged polygons and i think ZEEngine (battlefront) too. But ZETools goes just up to 4-edged and the old meshviewer does only support triangles as far as i know. My viewer can display theoretically limited but unlimited to it's size edged polygons, but since zetools does not export i cannot test it so it's theoretically and to be serious you should never go over 4-edged

I see, thanks for the advice Anakin!
