Maya mental ray全局光照和焦散进阶视频教程The Gnomon Workshop – Global Illumination and Caustics in Maya & mental ray

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.
