Spaghettis were talking about Ambient Occlusion in the renders, and I wanted to see what modo's results were. Rendering with AO is simplicity itself - change the Color Output in Render Properties from Shadertree to AO - that's it!
I rendered with AO one of the spy bots as well as a printer I modeled to see what they look like. Mind you, these are all default settings - I was interested in the default results before I started messing things up.
I think they look pretty alright, but now I want to tweak the settings. I like how the detail (albeit grainy) in the printer looks good, but with the default settings you lose some of the lines/separations between parts.
