Shader menu

C4D : all versions , all platforms.

Plugin shaders do not appear in the standard plugin menu, they appear in the texture menu. (some call this the shader menu)

To find the texture menu, create a material and click in the texture field. A menu pops up, which shows you a list of all the shaders you have available, incuding standard and plugin shaders, as well as any textures you may have loaded.

Your new plugin shader is in this list, and when you click on it, C4D will add it as a shader, to your material.

Also , this solution may apply.

NOTE : Post Effects (like white lights) show up in your render settings.
