Irrlicht Engine

Hi !
I am new to Shaders .I just started learning nVIDIA's Cg Shader language . But in the documentation of Irrlicht only GLSL and HLSL are written.
Is anybody using Cg(C for Graphics) with Irrlicht ?

Cg is more or less the same as HLSL. You can use your Cg shaders without any changes or with only small ones, depending on the used feature set. This works fine for directx. If you need OpenGL, you have to write a GLSL version of the shader too, as Irrlicht does not currently support Cg.
