In this lecture, Frederic Durand demonstrates a variety of techniques for using indirect illumination within Maya and mental ray. Indirect Illumination with Final Gather is arguably the most useful lighting method in mental ray and in this lecture Frederic demonstrates how to light using fill lights, bounce lights and IBLs (image based lighting) with an emphasis on the artistic and technical challenges that Final Gather brings to the table. Final Gather creates a very natural non-directional illumination. Artistically, it is sometimes difficult to give character to this type of lighting. Technically, it is difficult to master, as it is known to create blotchy patches of light in still frames, or flickering noise in animation. Production proven solutions show how to balance the different settings of Final Gather to minimize artifacts, promote fast rendering times and achieve artistic control. Compositing is addressed as an integral part of any lighting workflow, as it helps to work more efficiently, while rendering in passes is critical to successful lighting strategies. For those interested in mastering mental ray, this title offers invaluable techniques from an experienced industry artist.
