Title: Reolading exr in frame buffer for tone mapping
Post by: ACGI on 2016-07-20, 20:49:00

Hi All,

Apologies if the topic has been discussed already, I couldn't find anything about it.
I am tryng to reopen few exr renders in the frame buffer. My only goal is to change the tone mapping.
Is this someting that can be done?

I have read about resuming a render but I didn't take the further steps and seems like I can't do it since I didn't save the extra passes for the denoising.

Regards,

Giacomo.

I guess my exr is no more linear so not sure I can reverse engineer that but I hope so.

It is only possible to continue rendering using a special Corona EXR (https://coronarenderer.freshdesk.com/support/solutions/articles/5000501975-corona-exr-format) saved using the "save vfb" option in scene settings, or from an autosave. It won't work with a "regular" EXR. If you have a Corona EXR saved, you can use the "Resume from file" option in scene settings, and then stop the rendering. This will give you your EXR for further post processing.

There have already been requests about the ability to load images into VFB, so I am sure this will be added in the future.
