Which way do you mean, because neither seem to work correctly for me - im sure im doing it completely wrong

also the same thing happens with bounce, it's either access denied. or if i put it in the normal compile window, nothing seems to happen

ta for your help

example...

http://homepage.ntlworld.com/simon_elliott3/vvis.JPG

when i do that the compile process window is just blank :/

Thanks for trying to help me leperous, but i still can't get my head around this glview thingy, whenever i try to run it it either doesn't seem to do anything or gives me a list of parameters which don't make a whole lot of sense to me. im sure its staring me in the face, but its bugging the hell out of me.

first i noticed the leaf problem was after i installed a projecter and used the project decal entity, i've since deleted it but im still having the problem.

I've updated my image to show the way i have the expert tab set up - thanks to your tutorial. could you please point me as to what i'm doing wrong now

my compile window
