Eat 3D – Shader Production – Writing Custom Shaders with CGFX
FileSonic -,- Filepost -,- FileServe -,- Torrent
In this DVD, Instructor Luiz Kruel guides you through writing your own shaders, primarily with the CGFX shader language in Maya. Luiz starts off with getting everything set up in Maya and then writes a simple Lambert shader from scratch. From there Luiz builds upon the Lambert to create a Fresnel and Phong shader. Once the Phong shader is defined, Luiz begins to add textures like diffuse, specular, normal, and cubemap. He then demonstrates how to manipulate UVs and even how to do vertex animation. Luiz then goes into such techniques as blending textures and colors, creating a car shader and pulling everything together to create a full character shader with SSS. Finally, Luiz demonstrates how to take what you have learned into UDK to create a custom shader using the standard material nodes.
