Small update:
I was playing around with trying to replicate how bump mapping is done in CloD in order to use some new bumps for the modified terrain textures. Here's what I came up with (Ali, please tell me if this is wrong, as it's a bit weird, but actually seems to work)... Firstly, I extracted a normal map with crazybump- and then the red channel of the normal map, I put into RGB of the modified bump. The green channel of the normal, I put into the alpha channel. Then I saved out as DXT5 (there was a little bit of trial and error in this). Anyway, I tested this new bump out in CloD's evening lighting. Here are some pics...
(please ignore the white empty parts, there's no texture in there yet)
There's still quite a way to go with these textures, but I should proably say, I'm becoming pretty inspired to push ahead now. I'm quite happy with the way things are looking already. The bump map is working (even though I might be doing something wrong there), and I generally feel that the terrain is starting to be lifted to quite a nice level graphically. In motion, things are really starting to look great.
Ok, back to work,
