I'm using a 1024x1024 texture, I think thats about as big as I can comfortably get without causing too many problems for other cards - thats why I was thinking about joining different terrains.. so I dont have to stretch it anymore, or use a bigger texture size.
My base texture (the first texture) is stretched across the whole terrain.. this is the one with the combined lightmap - so in theory.. YES, you could add things like bomb blasts and skidmarks directly to the texture - although, remember its stretched !.. so its not gonna look as good as it should.
(I think 1 pixel on the actual texture = 4 or 5 pixels on the landscape)
Also I seem to remember the other guys saying something about not all cards support directly writing to the texture. :(
