Tempest, I know this is coming in late, but I definately have a solution for you on that forest thing. I use it all the time. Follow Rosh's tut closely because he uses the same technique I use, just never on grass. Create a terrain and enter the editor. Don't load a new terrain though, just run your mouse over the spikes button and pull it to the right until you find the right setting for you. Exit the editor. Apply the right map and render. Voila! Have a good one! Schnaps
