FX Composer is a powerful integrated development environment for shader authoring. With support for DirectX and OpenGL, HLSL, COLLADA FX, and CgFX, as well as .fbx, .x, .3ds, .obj, and .dae formats, FX Composer provides true cross-platform functionality.
We strongly recommend that you read through the Quick Tutorial (linked from FX Composer's new Start Page), as well as the User Guide (also linked from FX Composer's Start Page) to get a good understanding of FX Composer's extensive capabilities. These include Shader Library integration, ShaderPerf analysis, animation support, COLLADA support, scripting, effect and project wizards, customizable toolbars and layouts, and much more.
The release also bundles mental mill™ Artist Edition, which allows you to author shaders visually by connecting nodes. You can export shaders from mental mill™ Artist Edition to FX Composer, where you can apply them to real-world geometry and perform more complex operations.
