In this RenderMan for Maya tutorial, we will learn the successive steps of creating a photorealistic soap bubble shader. From a reference picture to the finished shader, these videos will show how to choose the shading models and surface parametrizations to use. We will go over the math and physics involved and how to derive a shader implementation. We will address the issues caused by using raytracing as well as animation within the shader and support for use of the shader with Maya's particle system. Software required: Maya 2008 and RenderMan for Maya 2.
