Brightness compensation button in material setup

[astudio]

I think it will be useful to have an option for automatic darkening of diffuse depended from glossy value.

Just to keep overall brightness of material the same. This may be some button. Don't need - don't press. Is it possible at all?

This would be good for work with clients. It's very hard to explain to constructor the theory of lighting, when he will ask: "I asked only polish, why it is brighter now?"

There is never be photoshop in VFB, you ask things all in one, it is impossible, more than that - it is not convenient. This thing you should have realized in first years of learning CG

Yep, render to elements, compose in compositing software. No need for rerendering, nor for magic buttons in material.

Yes. It was stupid request. Just delete it.
