Well, I have 3 meg of RAM....but the polygon count of the scene I'm having problems with is nowhere near what I usually do....it's really a simple scene....I've rendered much more complex scenes without these kinds of problems.....as for the textures, I doubt they're a problem.....the vegetation is what's causing the long render time (as always happens) but the textures are the same.....

And for some reason I didn't get the sample scenes when I downloaded it....either that or they're somewhere I can't find.....
