I wanted to do a little joke unit to try out the s3o format a bit and for a short spoof movie but now I'm stuck. After solving the usual beginner problems I now don't know what's wrong:
My problem is that the unit itself is fine in Upspring but not ingame. That is the unit shows up (i.e. I have given it a radius and so on) but the UV mapping has gone mad...
Here a screen from Upspring:

And ingame:

I don't know what's causing this. Well maybe one thing: Do s3o models have to be "closed" (you know - the same thing you need to have proper stencil shadows)? Because one part isn't and right now that's the only flaw I can think of...
Thanks in advance!
