MapBuilder currently utilizes only the (modified) water effect, and shadowmapping matrix calculations from shade-c (shaders are totally rewritten), everything else is removed. the new exponential shadowmapping is simply better and faster than the old variance shadowmapping.

in fullscreen I can get now over 30 fps, positioning the camera as seen above (maybe triple buffering, or using shader model 3.0, or loading the level from wmb - except grass - boosted it, I don't know), using 10000 grass models animated (using only ambient, but the shader enables using diffuse, specular and emissive too), with self shadows, without shadow cast by grass. I'm now satisfied with it later I will make a demo of this shadowmapping separated from MapBuilder.
