The Gnomon Workshop: Global Illumination and Caustics in Maya & mental ray
Lighting and Rendering Series Vol. 4 with Frederic Durand
Software used: Maya, Nuke | Project Files: Included | 1.30 GB
In this lecture, Frederic Durand demonstrates a variety of techniques for using Global Illumination and Caustics within Maya and mental ray. Global Illumination and Caustics rendering techniques use photons as the method to create natural lighting phenomenon. Photon based lighting allows light rays to bounce and create complex effects that are not possible with other rendering methods. The training begins with an introduction on Global Illumination theory and quickly moves into how to control the basic GI render settings. Fred shows how to balance accuracy, intensity and photon emission to create fast, production quality renders using Global Illumination alongside of Final Gather. The technical and artistic challenges of caustic lighting are covered in great detail. Materials such as glass, shiny metals and translucent plastics are used as case studies. 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 any successful lighting strategy. For those interested in mastering mental ray, this title offers invaluable techniques from an experienced industry artist.
