Ok after doing some heavy google work, I was able to get the full kitchen interior inc. materials into blender.
I exported a small part of it into DTS and packaged it into a static shape just to test it, and it worked surprisingly well!
Now this is cool n all but I'm pretty concerned in that even if you exported sections of it at a time, there would be major fps issues as there are a LOT of polys :/
I'm going to try exporting some of this together, and see how it goes.
also, if i remember correctly there was a button that automatically converted tris to quads, can someone post what it is? - alt j
