Thanks for the nice comment. These two images are renders using Terragen 2. Renders like this at 1024X1024 take me (on my old 2-core computer) about 2 hours. Converted to jpg for a skybox, they are the same as any jpg image regarding resources I imagine. You will have to ask the mapper experts about this to be sure.
BTW, I sent a full set of renders to JohnnyE this weekend for the skybox. If anyone else wants them, let me have an email and I will send them over.
The announcement regarding UDK4 came at a good time for this map, hoping now to make serengeti the first 3rd party map for urt-hd using the new engine.
Been working quite a lot with udk3 and hope I can import my materials/mesh into the new platform. I'll post a couple of screenshots of the map in UDK3
Model and model material is placeholder only at this stage and I really don't want to give too much away at this early stage but here's the promised screenshot
