Join Dariush Derakhshani for an in-depth discussion in this video Irradiance mapping, part of Learning V-Ray for Maya: A Professional Reference Guide.
In this video, we'll be taking a look at the Irradiance map engine with VRay's GI.…Go ahead and open GI_Scene_Engines, my file that came with our videos.…And you'll see a scene set up like this with renderCam as the primary camera.…In the render settings, you'll want to go into the Indirect Illumination tab and…keep your primary bounce at Irradiance map, but go ahead and change the secondary…bounce to None. So we have a single Irradiance map bounce.…
Now, we'll take a look at a non-GI render of the scene and we'll go ahead and render this.…We can see that the distributed render is helping with the Irradiance map…calculation, as we wait for that calculation to be done.…We'll get a single bounce solution that gives us a lot more illumination in our…environment when compared with the non GI render that we see here.…We get light into our box and into our sculpture with a pretty nice amount of detail.…
As a matter of fact, we get a lot better detail out of the Irradiance map than we…do from a light cache, but not quite as accurate as a brute force.…
