You don't care about general resolution, the trouble is on skin color e not on rendering quality.

All render lights setting are the same on better quality, low quality is only for fast test.

This two rendering are just to show the main scene, which seems (to me) with a good general illumination. (resolution setting is better then those following for skin tests, but not the best possible, so don't say any word :) )

I use IDL, Gamma Correction and EZSkin for all final renders.
