I've made a god quality model of a outdoor terrain, loaded into truespace, then wanted to export it with Truegene. But then it simply said to me:
'cant create face'

So what do i do now? (I used alot of vertices...)

oh. ok. Solved the problem myself: I found out that Truegene obviously cannot handle more than ~16000 vertices. Made a lower-poly-version of the terrain. From 17000 to around 12000 vertices with the polyreducer of Truespace.

How does it look in game? Can you post some shots?
