Specular & Diffuse controls in the LIGHT

Usually, when lighting, I need to create lights which are either DiffuseONLY or SpecularONLY, or some variation (strong spec, weaker diff; strong diff, weakspec). Also, it’s very useful to have the spec. exponent as a control on the light. It may be more ‘correct’ to have these associated with materials, but very often, to achieve the desired look, you need to control these parameters per light. Please tell me there is a way to do this in touch… :neutral_face:
thanks for any help,

No, the Phong MAT does not currently support this feature automatically.

If you have access to a GLSL shader writer though, it’d take him no time at all to extend the Phong MATs code (that is outputted via the Output Shader button) to incorporate this type of behavior.
