Join Adam Crespi for an in-depth discussion in this video Overview of ambient occlusion and specularity, part of Maya: Game Prop Creation.
In this chapter I'll look at Ambient Occlusion and Specularity as a way to add…realism and detail to a model.…We can model high-res objects and use the occlusion from them on low-res pieces…to look like they have more detail.…In previous videos, I have painted in things like rust and dirt and wear, such as on the gas pump and tools.…In this video, I'm going to take things like my shutter here and my Toolbox that's missing its…handle and use the Ambient Occlusion as a foundation for dirt and rust.…I'll do this in two different ways.…
For the Toolbox I'm going to put a ground plane under it and render the occlusion into the UVs.…What we will get there is black on the bottom, which is okay, but more…importantly, occlusion that rises up the sides of this Toolbox in a place that…we naturally see rust if this was left out.…For the shutter I have modeled a high-res shutter, and while the poly count on this…is ridiculous to use in a game,…it provides a terrific high-res source to bake occlusion.…I can then put that occlusion onto a low- res box, and it will look like that shutter.…
