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