Yeah, I'm sure it's been covered but I can't find a thread that talks about the properties settings. Specifically

Shadow Blur Radius, Shadow Samples, Shadow Min Bias.

I have it set to 30% intensity and a dark, orange-yellow color on the defuse and yellow on spec. Just not sure about the shadow settings. Any help would be greatly appreciated.
