increase indirect light


Recommended Posts

if you select your main light source (mrSpot, etc.), then go to the Mental Ray Indirect Illumination rollout, check Manual settings, and increase your Energy of that light. This will brighten the photons emitted this light. Also, you can decrease the decay of that light the same way. Increasing number of photons will also brighten the scene, but at a rendering time cost.

You can increase the final gather scale in the renderglobals to a value higher than 1. You could also set the color gain of the IBL node or the camera's environment color higher than 1 as well. If you increase the energy of the lights it will only effect photons and not final gather. Although you are only adjusting final gather you may still need to turn down the intensity of the lights a little bit because the overall lighting will be brighter.
