1. Rendering with material without radio flag sometimes caused scanline errors. The 'rad' value for rendercore loop wasn't reset in all cases 2. The color didn't truely match the color when using 'radio tool'. Cleaned up a few old lines in rendercore loop... accidentally one calculation was done double. 3. When adding new radiosity block, 'max iterations' is set at 120. this prevents noobies/experiment from going into radio-solving with a long itteration time (it exits at convergence < 0.1)
