Hi.. sorry to be unclear... I'll check that script out. I meant I think raytrace/idl/pixel sample setting are double what they should be for a simple render and run slow. Here the settings are at half but with another light added... I need to tone down these lights as this looks pretty bright for a 50% gray surface. Maybe all lights should total 100% white at 100% intensity and not go over that... I'll try cutting the lights so they total "1.0".
