Realtime Shader Basics

Realtime shaders are designed primarily for games and interactive media development. Using realtime shaders allows artists to apply in-game shading and effects to characters and environments from directly within the Softimage interface, without having to involve developers.

Support for two sets of realtime shaders is provided with Softimage — one set is designed to operate with an OpenGL® display and the other designed to operate with a DirectX9 display.

The extent to which you can use realtime shaders depends on the graphics card and/or drivers on your machine. For a list of graphics cards that are certified for use with Autodesk Softimage, see the graphics cards certification page at

This section provides an overview of using realtime shaders in the render tree and discusses some concepts and features that are common to both OpenGL and DirectX realtime shaders.
