Hello!

I created a simple scene that shows my problem. There is a blue wall, this color is on brass reflections and table. If I would like to change color in photoshop of the wall and all of blue reflections, there are plenty of solutions for example color range.



Using CESSENTIAL_Reflect I have every reflections, brass, wall, table. It is possible to render only blue wall reflections on every objects and materials? Decompose reflections? To have blue color mask directly from render. Or I am over engineering it? Do it in photoshop and go away ;D?

It should be easily achieved with mask propagation of reflections for masksID, although glossy reflections and bumped surfaces would be harder to control a bit in post, also you will need to render it with really low noise threshold 2%-3% and on high resolution (example below with IR low quality, you can see seams, but overall works): https://coronarenderer.freshdesk.com/support/solutions/articles/12000066916-how-to-use-masks-with-reflection-refraction

You will need to test this with Corona v6 Daily build.
