I see the light mapper has more properties and features in b10 (by looking at the videos), but does enlighten get ANY faster at all? I've followed the hints people have posted (made the terrain have it's own light map parameters object, that sets the resolution and color resolution to 0.1 each), but I'm not seeing any speed gain. I can't set the terrain static, because then it looks like the trees are floating in the distance as the terrain is then basically flat shaded. Enlighten has been in "Enlighten - LightTransport" for about 10 hours now, and it appears to be about 1/3 complete. I have a quad core i7, and bumped it up to "high" cpu usage, and it is indeed devouring tons of CPU. I also have 24GB of RAM. So I don't think it's a resource issue.
