if you download my editor, or this demo: http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=430852#Post430852 , you can get some terrain shaders. they utilize vertex or pixel lights, switchable by commenting/uncommenting a #define line. in next update I will provide shader model 3.0 terrain shaders, having more instructions available, so they can work with 8 lights (maybe the shadowmapping demo already features it, I don't remember). but they lack normalmapping.
