Chaos Corona 12 for 3ds Max - Daily Builds Discussion

[maru]

Just curious - anything changed between RC1 VFB and previous daily ? On 3990WX, VFB was always laggy/unresponsive, especially when zooming in, moving around the image at higher resolutions etc.

VFB 2.0 (previous daily) solved that for me, it was super snappy and responsive. Installed RC1 yesterday and VFB feels thesame like always did. Zooming in or out takes sometime 2-4s. Panning inside the image at 100% zoom is laggy and whole max freezes.

I was not able to reproduce it, definitely no 2-4s freezes and no Max freezing. Maybe it's scene-dependent? Could you share a scene with us (archived with all assets) here: https://support.chaos.com/hc/en-us/requests/new

Hello Corona Renderer team,

In the latest changelog of v12RC2, there is a bug fix for Scatter mentioned:
"Fixed issue with missing icons in Max 2025."

Is this fix only for Max 2025, or are previous versions also affected? I had this bug in Max 2022 and 2024.

Thanks in advance

In version v12RC2, I can't use it
Sample scripts available in MaxScript
CoronaRenderer.CoronaFp.exportScene @"C:\Corona\myscene.scn"
I want to export the scene through the script, but it seems impossible to achieve

Hi, can you explain what exactly you would like to achieve? Export a scene to Corona Standalone? Or Vantage? Or maybe something else?

[Frood]

Just checked, it's broken. And it has been already broken in RC1. It is just about the standalone (Edit: and vantage) export function of the Corona interface. A correct call (with all needed parameters) would be for example

Code: [Select]

CoronaRenderer.CoronaFp.exportScene @"C:\Corona\myscene.cdo" 0

All you get since RC1 is

Code: [Select]

-- MAXScript Listener Eval Exception:
-- Unknown system exception
-- MAXScript callstack:
-- thread data: threadID:10096
-- ------------------------------------------------------
-- [stack level: 0]
-- In top-level


I think adding that vantage button broke it. Daily 0706 did it correctly.


Good Luck

Yes, I would like to be able to export to vantage through the export function, and script a button, just like Vantage's toolbar in max
If you need to modify the scene, you can use this button to refresh the export and reload the scene in vantage

I was able to repro this issue and have logged it in our system for our devs to review. Thank you for reporting this.

Most of the corona and Native 3ds Maps are not supporting in Vantage. Like Tile Map, Color Correction, Corona tile map.
Even Material Texture and color not accurate on vantage like on 3ds Max corona renderer .

Hi, the fix should affect 3ds Max 2024 too, and may affect earlier versions. Feel free to test and report back.

Hello everyone,

Tried corona renderer 12 and since the release of 07-06-2024 and for both RC (1&2), I found out that the Intel denoiser isn't working as it had to in the previous versions (even for corona renderer 12 pre-releases). The result is kind of blochy and isn't acceptable at all. Even Nvidia AI denoiser, which is a fast preview denoiser, is giving more interesting results than the Intel one, nonetheless it is a fast preview one and can't be effective.
I send your two tests one with version 11 and the blochy one with version 12. I've made other tests on other scenes to avoid any interference due to the file itself, same result.
I hope this can be resolved in future release.

Greetings.

This is confirmed and we are investigating. Thank you for reporting this!
(unrelated to the root issue, but please note that rendering just 1 pass and denoising it does not make much practical sense - most likely the base image quality will be always too low)

Hi everyone,

I've been testing Corona 12 for the past few days, and have one request, is it possible to have the Corona smiling face emoji back? It was really helpful to understand when we are rendering. Now every time I have to check if the interactive render is running or not.

Thanks in advance

[romullus]

+1 Yes please, bring the smiley back. If you think that yellow smiley is clashing with new corporate Corona philosophy, then maybe replace it with spinning Corona logo, but some sign of rendering progress would be highly appreciated.

[brr]

+1 bring please the smile back, or give an option to activate it in system settings.

Not removed for any reason other than rewriting to QT changes how this could be done - and unfortunately, for the release of 12 we'll have to focus on other things. But we do aim to bring it, or something as an indicator that stuff is happening, back. I see no reason why it shouldn't be as charismatic and fun as the old one was, when it does come back :)
