Overexposed RawReflect

[dj_buckley]

I'm not even sure this question makes any sense but ....

If my main render looks good in terms of lighting/exposure/materials/tonemapping BUT my Raw Reflect pass is horrendously overexposed - what (if anything) does that tell me about my lighting/exposure/materials?

I think the Raw Reflect render element just shows which materials are reflective, and how reflective they are, so if it's white, it just means that the reflection color of the visible materials is set to white (I may be wrong as I sometimes mix different render element names, but that's how I think it works).

Maybe you should use the element "CESSENTIAL_Reflect", which will look correctly exposed.
The raw component instead, should be saved at 32bit (linear) and composed using a mask that tells it how much visible it should be on the different objects. I used it a lot in Vray but now in corona I usually don't need to work much in post! :)
