Title: Corona Map Output - Use photographic exposure mode in Color mapping
Post by: johan belmans on 2014-06-25, 10:56:21

Hi

Corona Map Output doesn't work with "Use photographic exposure" mode in Color mapping.

My backplate in the direct visibility override slot was still affected by colour mapping.
When I disabled "Use photographic exposure",  the backplate wasn't affected anymore.

cheers

Johan

Edit: I made use of Alpha 7 RC 1 build

You have to re-render in order to see the changes. It does not propagate in realtime.

If it, even after re-rendering does not work the way it should, then it's indeed a bug :)

Hi Rawalance

yes, I re-rendered

Another thing, but this is maybe not a bug:
-If I do not use "photographic exposure mode" but the default color mapping with the "Corona Map Output without the Affect colour mapping unflagged", if I change the EV value, the back plate is slightly affected as well. This is not what I expect when I try to match lightning conditions on my model with the backplate.

Secondly (more a feature request):
- Show  the values of the color mapping by photographic exposure  aswell in the frame buffer, just like the default colour mapping.
