Title: IPR refresh often at change of tonemappng paramaters
Post by: Stefan-L on 2024-11-17, 10:51:04

as titile says,
in 13 daily i often see that the full ipr refreshes, even if i only change a tonemapping operator in vfb,  like white balance, exposure, acis or lut settings etc.

hop that can be fixed for release

Same Issue also with different Cinema versions. Downgraded corona because of that. Impossible to work with.

i see now even LIGHT MIX changes trigger a total refresh of the scene (parsing....)

- so IPR is hard to use at all,
- the sense of light mix is broken in this version (v12 rc2)

I am not sure what you mean about V12 RC2.... do you mean Corona 12 Update 1 Release Candidate 2, and not Corona 12 Release Candidate 2? Also, does this apply to the final released version (of whichever one you mean, Corona 12 or Corona 12 Update 1), since any Release Candidates are superseded by the final releases?

"in 13 daily i often see that the full ipr refreshes, even if i only change a tonemapping operator in vfb,  like white balance, exposure, acis or lut settings etc."

the same in Corona 12 update1.
How is it possible that such an important thing is not tested before the release of an official version?

I'm not sure, which version others are using, but I'm using Corona 12 update 1 and I can confirm this issue.
Hope this will be fixed in a hotfix :)

Same Issue also with Corona 12 Update 2. I am again downgrading to C11U2.

Hello corona team
 
Meanwhile it is 8 months since the first post about this problem.
In Corona 13 RC2 it is still there.
Please can you explain why this is still not fixed.
Thank you.

It doesn't make any sense to use the Release Candidate version or report issues in it. Please update to Corona 13 and let us know if the problem is still there: https://my.chaos.com/download/build?product=Corona&platform=Cinema+4D

Don't know if it's a "bug" or by design but it happens only when the render camera has a Corona Camera Tag.
It's the syncing of the tonemapping parameters / stack from the VFB to the Corona Camera Tag that triggers the IPR refresh. Delete the tag and no more IPR refresh.

Hello Maru

I tried Corona 13 and it's the same. It also was in corona 12.
@ John: If i delete the camera tag, i lose the corona tonemapping controls, for example no more DOF settings...
One trick is to delete the white balance in the tonemapping controls, then it works. But if i i check bloom and glare, IR refreshes again.
