>> By the way lighting has nothing to do with it… << Lighting has everything to do with it because for any given RGB value assigned in the material editors, increasing or decreasing the light source will change the rendered value of the assigned material. If the lighting is too hot it will not fall within the legal NTSC color space. The formula determines YIQ values from RGB and then relates them to legal NTSC color space. Y = Luminance. I/Q is NTSC's color wieghting distribution. Gamma is also effected by Lighting because depending on the light level in the scene, the assigned RGB value will change when rendered to a different RGB value. Which makes calculating YIQ based on RGB values in the materials editor pointless without considering lighting and gamma. I'd like confirmation that the Gamma formula in Foley etc. is the actual gamma correction formula used in 3DS.
