Creating an ambient-occlusion rendering pass with custom materials
When we're running an ambient occlusion pass in this scene, we often need custom materials, rather than using an override on everything. What we'll see a lot of times is that an override works well on the matte surfaces. But doesn't do so well on glossy surfaces. And definitely not on transparency. In this scene, what we're seeing is a darkness around the surface mount cans on the bridge. And those are metal and shouldn't get additional darkness on them like that. We're also seeing that the glass is either catching occlusion, or completely obscuring what's behind it. We need this glass to be more transparent. And so we need a different material. Lastly, the Terazzo floor is gathering too much darkness in the occlusion. And although it should have occlusion in the corners, it doesn't need to spread out as much. I'm going to release the override and make some custom occlusion materials, which I'll apply here in the scene. I'll press M for my material editor. And f10 for my render set…
