More cool stuff from Knives, resident CTRP tool/resource locating maniac!
This little tool called SpeedTreeRT can use a special actor to create millions of trees in any Unreal level and manage to keep the FPS high. I'm not sure if the demo can be used just yet, I don't have 2004 yet so I can't check it out, but perhaps one of our other Unreal mappers would find it interesting. Seriously, the tree effects marvel those of Far Cry.
Here's a pic showing how huge the forests can get:

And another pic showing the ridiculous detail in the trees:

I think this would be very useful for the more forest-y regions of the CT universe, like Guardia Forest, Denadoro, and especially the Prehistoric era.
Enjoy!
