Title: Change Material parameters globally
Post by: Alex Abarca on 2014-02-17, 06:16:22
When changing lighting conditions...Let's say from HDRI or sun. You might need to modify your your diffuse color settings based on lit environment. It would be killer if i can adjust all my diffuse channels by certain percentages to compensate for lighting conditions.

Perhaps change Reflection, Refract, AO params as well.

This could be done via script, but I see no point in putting it inside the renderer. It would just clutter the UI. Changing all materials because of lighting is also a bad workflow, realistic materials should be largely independent of lighting

That just means you have done your materials wrong in the first place. So learn to make them right. If you change lighting, and your scene is too dark on bright, then you compensate with exposure adjustments, not materials. That just does not make any sense. If Corona had implemented additional settings to compensate for various wrong workflows of various users, UI would have thousands of buttons.

Yeah that's what I meant, I remember preparing a script in mental ray to correct these values, but OK. I was just thinking.

No, they were done right... what I actually meant is that models might come from purchased repositories, and your lighting workflow might be different from the models you  purchased. Or perhaps a person works in an office where there are several vizzies and you want to correct their reflect, AO, refract.

Anyhow I was just stating possible additions to the software, but maybe I should sushh...:D
