Join Aaron F. Ross for an in-depth discussion in this video Faking GI with an Arnold ambient occlusion filter, part of 3ds Max: Tips, Tricks and Techniques.
- [Instructor] Previously in this weekly series,…I demonstrated how to save render time…by disabling global illumination diffuse rays…in the Arnold renderer.…Instead I used an Arnold sky dome…to provide an even, ambient light.…That movie was titled…Approximating Global Illumination in Arnold.…This week I'll build on that technique…by adding an ambient occlusion light filter.…Here's the image rendered without the light filter…and here it is with the light filter applied.…
So I'll switch bath and forth between those two images…a few times so you can see the difference.…This is actually the original use case for ambient occlusion…way back in the 90s.…A flat even wash of illumination is added to the scene…and the distance between surfaces determines how much…of that ambient light is blocked or occluded.…The result is darker shading in the corners of rooms,…the crevices in and between objects…and anywhere the ambient light would be blocked.…
The rendering is not as realistic as global illumination,…but it's much faster.…
