Gnomon releases AO in Maya & mental ray

Tuesday, January 6th, 2015 | Posted by Jim Thacker

The Gnomon Workshop has released Ambient Occlusion in Maya & mental ray, the fifth in Disney and DreamWorks veteran Frederic Durand’s series of guides to the fundamentals of lighting and rendering.

An invaluable guide to mastering mental ray
In the video, which lasts 225 minutes, Durand demonstrates a variety of techniques for indirect and direct lighting using Ambient Occlusion within Maya and mental ray.

He begins with an introduction to AO theory, then moves into how to control the look of AO lighting, using the built-in shaders mib_fb_occlusion, mib_amb_occlusion, mib_fast_occlusion and mib_bent_normal_env.

The video also explores advanced concepts like environment lighting, refraction and transparency to ensure accurate results from complex situations; and explores the need to render in passes for compositing work.

Previous videos in the series covered light and shadow, direct lighting, final gather, and GI.
