Thanks for answering.
I've read the manual (most of it) like half a year - a year ago. I followed the tutorials but I couldn't find anything about terrain normal mapping. I *guess* NM and parallax for terrain entities are not native to 3DGS which wouldn't be a problem if I could find anywhere custom shaders to d/l. Still it would have been best if I didn't need to add/write extra shaders.
About specs, I don't understand what you mean, I simply want to make a RTS and find a good balance of speed/no of textures per terrain, to use. I want small objects to be normal mapped and parallaxed instead of entities.
