Fixed a shadowmap rendertexture NRE caused by an incorrectly ordered null check (didn't cause any actual issues, just an error message). Also did some minor performance tweaks to the shader to make it use keyword toggling for the softness falloff exponent. Added a dirt material to the demo ground plane to better represent real world conditions.

We think that is more than fair. :) We also would greatly appreciate it if some sorrt of credit was given if you do indeed use these textures in a published game. Other than that, keep on creating and have fun. :)
