Hi Yes, polygonoffset methods are presents in ShadowMap class only, but I use a technique derived from StandardShadowMap which redefines the polygonoffset variables and here we have no methods to set.
However, I've tried polygonoffset tweak and the final result is much better even if not "perfect" in all scenes. Thanks for your suggestions. However I will try the new robert's technique also in next days. I still have to try the the GL_CULL_FACE option in my models...
