yes, it is the very same I made for shade-c, I just commented out the shadowmapping related parts (I modified the original shade-c terrain shader what I found a bit illogical in connection with its skin arrangement, now it is much more easy to use. and it was too slow because of its high quality features I removed partially, but I made several separate but compatible shaders to enable choosing the desired complexity).

shade-c 0.91 applies variance shadow mapping, its shadow area positioning is okay for 3rd person cameras by default, but I need a very free rts camera, where it behaves very badly. finally I could achieve an acceptable positioning, but in some cases black artifacts appear that can be eliminated if shadow fade-out is not used. moreover it requires further post-processing to get smoooth shadows on terrain (it is very pixelated in some cases on higher terrain slopes), and better shadow edges. but probably it is not so easy, and maybe has a bad effect on performance, so I don't know what I can achieve... currently it is okay for a shooter in a flat world with sharp (but not pixelated) shadow edges.
