Thank you, Gentlemen.
We'll keep going with the solutions suggested by maru until any solution comes up from the engine itself.

[Max] Bug Reporting / Refractive Surfaces Blackout
« on: 2025-08-22, 12:06:52 »
Hello,
We came across an unusual bug that actually happened to us twice in different scenarios.
When there are specific surfaces in the scene using refraction, they sometimes seem to obscure the camera and fill the alpha entirely, even though they don't occupy the space nearby.
This also happens with displacement off. It feels like the refractive surface casts some sort of infinite "death ray" that will obscure the view once the camera passes through it. It can be "fixed" by applying a normal modifier, but the main reason behind is still unresolved.
In this particular file, the problem happens at frame 16. Previews are in the attachement.
It's much easier to simply open the attached file and check.

[Max] I need help! / Re: Corona 13 + Vantage Animation
« on: 2025-06-17, 17:00:06 »
When I initiate a live link in VRay, I can adjust some Exposure, Filmic Tonemapping settings, create a temporary scene sub-state in Vantage. Then after I press "Render in Vantage" button - it keeps these settings, to my adjusted exposure settings are maintained.
In Corona I try to do the same, initiate the Live Link, adjust, create sub-state. Then I need to stop live link and press "Vantage Anim. Export" button as suggested. But after i adjust output settings, my previous exposure / tone-mapping vantage settings are reset, and i end up with overexposed output, with no way of controlling it.
Unless there's any other way?

I’ve created a request in the Ideas Portal as part of the broader topic of file output handling.
Feel free to vote here: https://chaoscorona.ideas.aha.io/ideas/CMAX-I-170
Maybe it’ll help move things forward...
Cheers

Thanks, Tom. One last thing - how can I modify and adjust color corrections in this process?
When I press "Vantage Anim. Export" the output window shows up, blocking the access to any other adjustments. I'm happy to check the documentation but i'm not even sure where to start. VRay workflow seems to be different.

Hello, I'm trying to render an animation using Corona 13 and Vantage - the problem is i have no idea how to do that. Your annoucement video just shows the output, but there are no resources showing the process.

Thanks, Tom, I added the idea here: https://chaoscorona.ideas.aha.io/ideas/CMAX-I-170
It would be amazing to get that, because we do love using Corona, but seems like this limitation affects so many of its features.

Hi,
Thanks a lot for a great (and pessimistic) answer!
Looking at your thread link, the issues were already there 6 years ago - that doesn't give me much hope for them being fixed either in Max or in Corona.
Funny thing - over 50% of our trouble using Corona would disappear if it stopped relying on Max file output. It’s been a consistent pain: render elements paths not being updated, PNG output error messages, and now this.
Makes me wonder - all these industry standard render elements are there: Velocity, WorldPosition, they even added Cryptomatte - only to be crippled by weird CXR-only methods, flawed output, etc.
Seems we have to investigate and simply move to V-Ray or other solutions.
Thanks again.

[Max] I need help! / EXR Output with Network Rendering
« on: 2025-04-11, 17:29:45 »
Hello, I'm trying to come up with a workflow for rendering animation and outputting EXR files.
During this task I came across multiple problems, I'm not sure whether they're on Max or Corona end.
My requirements are simple: 16-bit for most of the render elements, 32-bit for Velocity, WorldPosition, ZDetph and UVWCoordinates.
However, it turns out, it's almost impossible to get this setup when rendering either with Pulze or Deadline. When rendering locally, it's great - I'm using Manual "Add" Render Elements dialog inside EXR save options. I can add manually all passes and choose their bit-depth separately. When rendered locally I get Multilayer EXRs that meet my requirements above. However, as soon as I try submitting to ANY network solution, passes don't get saved - I end up with Beauty only.
I thought, maybe setting the depth-bit to 32 and checking "Automatically add render elements" checkbox could help, and it does - passes are included in the EXR but suprise! All of them are forced into 16-bit, even if main setting is set to 32.
So my only option for network rendering is to produce separate EXR files for each pass and in 32-bit depth, which bloats the disk space a lot. Is there really no other way? Looking for some suggestions, thanks in advance!

This is already known, and guess what - it is already fixed. Shall be part of the upcoming hotfix.
Can't wait for the hotfix then, thanks!

Hi,
Lightmix color drag-and-drop is already fixed internally and shall be in the upcoming hotfix.
Hi, Aram
Many thanks for the reply, this is great news.
There is one more inconsistency with previous versions: After turning the denoiser on in Render Settings, it doesn't turn on in the Frame Buffer, but has to be checked manually. I think old behavior made more sense.
Cheers

Aside from the feature talk, some changes in the VFB UI took the usability backwards.
In previous versions one was able to copy the LightMix color swatches just using the right click (or even simply by dragging one on top of another? not sure about that)
It's tedious going inside the Color Selection popup every time and using the eyedropper tool.
I'm not against refreshing the interface, but it would be nice to keep the functionality :)
