Message:

From Wojiech Lewandowski, "There was a bug in ShadowMap? camera view matrix computation. View matrix was wrong when light was directional and shadowed scene was not centered at zero coord. I fixed that and also modified cast distance to much smaller value. With former range it was possible to generate shadows with lowest LODs. "
