i have made some weapon models and modificated another downloaded from google sketchup. I can use it on red orchestra ostfront? and i can do this on red orchestra hos?
So in the end it doesn't really make sense to bother with google sketch up, learn the real thing
I model with sketchup as its easy and fast but i use 3ds to uv map and export it to whatever file format is needed. Simple as that.
Probably biggest problem is going to be that u might have invicible lines somewhere inside your model. Otherwise i haven't had any other problems. And no hassles for me.it won't be very well optimized and you'll always need extra steps. just do it in the best environment possible and avoid the hassles.
with udk 3 u shouldn't have any problems tho.
