> ## Usage

> LightDiffuse[i] = float4(r, g, b, a)

> ## Valid Enumerants

> r, g, b, a: floating point values

> ## Description

> Specify the diffuse intensity of the light. See the GL_DIFFUSE description on the OpenGL glLight manual page for details. See the Diffuse member of the D3DLIGHT9 argument to IDirect3DDevice9::SetLight method.

> The standard reset callback sets the LightDiffuse[i] state to float4(1, 1, 1, 1) when i is 0 and float4(0, 0, 0, 1) otherwise.
