[Solved] Photographic Exposure doesn't update

[karlingermano]

Hello,

I experienced even in the daily builds but now in the final release too that if I use CoronaCam with Photogrpahic exposure in the VFB (I replace the simple exposure with it) it just won't update when I change any parameter in the Cam (like ISO, ss or F stop).

Am I doing something wrong here?
Override isn't checked in the Cam tone mapping tab, and Simple exposure just works fine.

Thanks for the info,
Manó Karlinger

Hello,

Unfortunately I cannot reproduce this issue, could you please send over a scene where the photographic exposure is not working?

Thank you in advance,
Kris

Never mind, I was able to reproduce it with the Basic photographic settings in Render setup.
We've got it logged, thank you for reporting it!

@Karlingermano - just to make sure I understand the report right. Is this what you mean?
1. Rendering from a Corona Camera, default settings (no override, etc)
2. In the VFB, the simple exposure operator is removed and the photographic exposure operator is used instead
3. When you are changing the photographic settings in the camera, the brightness of the rendered image isn't changing <--- this is the issue
Note: when using IR, changing the camera properties does affect the exposure. The issue is only with final frame rendering and after the rendering is stopped.
