Using irradiance mapping, part 1
In this video, we're going to start demonstrating just how quick and easy it can be to set up a basic global illumination solution using V-Ray's irradiance mapping engine. To help us with this, we have loaded our GI_Room_Interior_Start file from the Exercise_Files folder. We've chosen an interior setting to test our GI engines as this represents by far and away the biggest challenge when it comes to getting a clean and believable global illumination solution. The plane gray material we have added to our geometry will increase the difficulty level for us, because, well, now it will help highlight, or show up any of the unwanted noise and blotchiness that can, and probably will, be present in our GI solution, at least as we are working to create it. Now we have no materials, no textures, no areas behind which we can hide these GI flaws. We will be using this same scene to build basic GI solutions for each of the engines we will examine in this chapter. This means we'll have the ability…
