Baking occlusion for rust and dirt

In a texture workflow aside from using Ambient Occlusion to add gravity to things and pick out all the little details, we can use occlusion as a foundation for dirt and rust on things. I am going to take my doors here, which I have cloned to make a pair and run an ambient occlusion bake as well as a color and then in Photoshop start to erode that away to make naturally occurring places of dust and maybe some rust and a few other things. What I have done then, aside from cloning the door and mirroring the Z frame over, is to put a ground plane underneath. This way it kicks up occlusion on to those doors, but in a front or ortho render it will flatten out entirely. I am going to make a new camera, choosing panels>Orthographic>New>Front and then I will focus in on those doors. I'll turn on my resgate and make sure in this new camera, which I'm going to name doors, that I change that film gate. Here under Fit resgate, I will make sure it's vertical and I'll zoom in and be ready to render…
