Nvidia and Alias|Wavefront today announced a new Cg plug-in that integrates real-time shaders into Maya 4.5. The Maya Cg plug-in lets Maya 4.5 users create shaders for DirectX-based platforms, such as PCs or Xbox, and view them in Maya's OpenGL viewport. The plug-in supports the CgFX file format (.fx) and provides interface controls and semantics to users and developers for editing shader effects in real-time. Since the CgFX format also supports both DirectX and OpenGL, developers may encapsulate a series of fallback techniques for rendering any effect.
The new plug-in is free, and available for download at the link below.
