Sometimes you may need a vray material to provide its own and there is a way to do that. If you make a vraylight material and assign a map to the color channel, you achieve a self-illuminated material in VRay. A VRaylight material looks practically identical to a standard material with self at 100.

A vraylight material emits a small amount of light with its multiplier left at the default 1.0. By increasing that value, you can make it throw off more light, though it additively brightens the color map you have assigned. This may be undesirable in some cases. You can make it give off more light without it brightening the map by right clicking the object and selecting VRay-properties. From there, you can increase the “Generate GI” value.

Many of you out there have probably run into the problem of needing motion in a GI lit scene. Usually this results in splotchiness and noise that swims around. V-Ray 1.50 has come up with a solution to address this. You can pre-calculate, and blend your irradiance maps together with the following steps.

First, make an with motion in it. I’ve made a simple reactor simulation for this scene. Here are the steps for creating that:
