[Max] Feature Requests / Re: Improved support of max colour management

« Last post by piotrus3333 on Today at 10:48:06 »

From my point of view, the Agx color management is quite seducing. Nice highlight falloff, colors OK, i like the desaturated aspect as will on high values.

I most of the time use your AgX matrix (thanks) + custom 1D curve made with Lutcalc, and it works quite well.

I also tend to have little photoshop editing at the end, so i like to have my colors right in the render, and i find it very hard to finetune them in the VFB.

So i thought of finding the nice color setups with a lut in Resolve, and then bake them with AgX in one single LUT.

are you using Corona Image Editor?

[C4D] I need help! / Re: Corona VFB vs Picture Viewer

Thanks for this James, I have checked the scores and my colleagues Mac should only be twice as fast. The issue here is that he seems to get faster renders through Corona VFB than PV whereas I don't. I am wondering if I am doing something wrong?

At least I know from those results you have posted it definitely isn't anything to do with only having 32gb RAM which I suspected.

No worries man, i didn't take your message as critique. I realize that my previous message probably sounded too defensive, but that wasn't my intention at all. I just wanted to explain reasons behind my setup and make it clear that my way of doing it is not the only correct method. If your method works for you better, then it means it si correct for you, but it never hurts to learn alternative workflows and have them in mind for situations where you might struggle with your usual setup.

Regarding tutorials, i don't think that Corona struggles in that regard, there are tons and tons of learning material out there, you just need to be able to distinguish more serious stuff from usual fluff. Most of what's been discussed in this topic has little to do with Corona anyway, but is more broad knowledge of 3ds Max and 3D in general. Learning material about this is widely available in all shapes and forms. Albeit it's not necessary directly connected with Corona, but it shouldn't be hard to translate the concepts between different renderers.

[Max] General Discussion / Re: Gamma Correction Tone Mapping Operator Removed - Bring it back!

« Last post by piotrus3333 on Today at 10:27:58 »

if "avoiding user mistakes" is THE strategy - was anything done about Tone Curve after this thread:
https://forum.corona-renderer.com/index.php?topic=40616.0

an updated tooltip or something?

No

well, there you go.
where is a sensible limit of protecting users from "breaking color management" (the non-existent one?) by adjusting gamma.

anyway..

+1 for Gamma operator, it should be there.

Have you checked the Corona Benchmark scores? There is a few different Mac Studios to compare from but here is the M2 Ultra with 64gb ram.

[Max] Bug Reporting / Re: CoronaMultiMap seed changes with animated camera

« Last post by romullus on Today at 10:21:12 »

If you are able to provide simplified scene where the issue can be reliably repeated, i think that would be very helpful for the team to identify and maybe fix the issue. https://support.chaos.com/hc/en-us/requests/new

[Max] Bug Reporting / Re: CoronaMultiMap seed changes with animated camera

« Last post by dzintas on Today at 10:07:18 »

Shouldn't happen, AFAIK 0 in Corona is just another valid seed, unlike in some other programs where seed 0, or -1 means random seed on each evaluation.

Splitting and moving the messages to bug reporting board.

Thank you for cleaning up my mess, and clarification!
Tried changing to some specific seed value, and as you mentioned bug still happens. Maybe less but just could be a different pattern.
Then its maybe problem with my setup. It's tyflow animated object, exported to vray proxy.
Maybe vray proxy part causes problems? It's building shaped boxes with a lot materials for facades, roofs, etc. Plus color variations for diffuse, with multimap that causes problems.

It would be nice to have your resolve/fusion workflow to see how you manage to create those LUT's... ;)

Between the -1.2 string, the "log" option in the vfb lut, the AgX ocio and DCTL (that i managed to install in resolve+fusion), the custom color correct node, well...it gets a little confused ;)

So when i color edit a 32bit image with Agx and dctl, i have trouble exporting to a lut to have the same result in the corona vfb

well,
feel free to ask the Corona Team why things are so convoluted with luts in CIE and frame buffer: https://forum.corona-renderer.com/index.php?topic=40988.0;all

if you're on 11.1 - you can use Gamma Operator 0.455 before LUT operators and the rest of invisible gamma transforms is cancelling itself out. no need for string option and this would work in CIE as well.

Fusion exports luts only for closed domain of 0-1 float, same as photoshop and most lut tools.
Easy way of doing that in Corona is Highlight compression 999 (Reinhard tonemapper x=y/(y+1)) - it acts as your log encoding - raw render is compressed into 0-1 range and lut can access those colour easily.
So in Fusion after creating hald image you need to apply reversed Reinhard on it, convert to arri logC3 and then AgX DCTL >>> and you have a lut that does Reinhard to one of AgX DCTL displays.

what are you trying to create exactly? a macro from Fusion is of no use if you do not know the math behind.
