[Max] Daily Builds / Re: Chaos Corona 12 for 3ds Max - Daily Builds Discussion

« on: 2024-06-28, 12:15:40 »

Hopefully, this hasn't been reported yet.
Since I moved to RC12 I have a Corona material with a multimap connected to diffuse and set to work on MatID....then another Multimap set to mesh element in order to randomiza each different ID. Well, everytime I reload the scene....most of the nodes are disconnected from the second multimap.
Hopefully the image will help to understand.

Anyone else the same issue?

Thanks a lot!

Atmospherics on 3dsmax Common settings may be the culprit, try to disable it and see whether things change. :)

I have managed to get a 8k render with no crashes by deleting each single render element. So, I guess, the issue is related to the file size.

How much RAM is Corona using? During a 8k stereoscopic image, doesn't go above 170 GB
 How many render elements are in the CXR? It crashes with 27 and with 2, same, no difference.
What is the file size of the CXR? The 6K is about 8gb with 27 render elements, the 8k version crashes (and doesn't save any autosave) even after 2 passes.
What happens if you do not save via Max dialog, just render to the VFB and manually Save CXR? I don't use the save in 3dsmax, I always use the save cxr from the vbf. It crashes as soon as I press stop (when the cleaning-up starts).
Does it happen if the image is not stereoscopic? Yes.
And as always with crashes, which version of Corona and which version of Max? Max 2022 with Corona 8 daily build Feb 02 2022), but it's happening with the official version 7.

After many many test, I really think it's a Corona or Max limitation on handling big files. I even tried to disable all the Forest Packs, same crashes with no message.

Hope this helps.

This is a very annoying issue.

Thanks

I think I have narrowed down the issue. I have tried different sizes....4k fine, 6k fine, 8k Corona crashes.
Is it possible Corona has issue with big cxr files? I have 256 GB of Ram....I wouldn't expect such a limitation on the render engine.

ANyone?

[Max] I need help! / Crash when click stop and no autosave

« on: 2022-03-09, 12:03:56 »

Hi all,
I have been having this issue for a while now.
I have a big scene to be rendered 8k x8k for a stereoscopic vr image. I have many Forest Packs and I have decided to double my memory ( I have now 256GB of Ram).
Now I can render the scene and through the night Corona managed to get the image to a good 2% noise (more than enough). Then I clicked stop (no denoise active) and Max crashes out with no notice.
I thought I could rely on the autosave, to my surprise, Corona managed to save only 0kb cxr.....so, no chances to get the image done.
This has been happening many times, I have tried with different secondary solvers, the problems seems related to Corona buy I might be wrong.

Any idea?

Thanks in advance for any help.

« on: 2021-12-20, 12:50:27 »

I am rendering a scene with some people walking. As long as I don't activate MB all good. As soon as I activate it, the rendering will crash.

Any clue?

thanks a lot! :)

[Max] I need help! / Alembic sequence and Motion Blur

« on: 2021-12-16, 12:37:24 »

Hi all,
I am rendering a series of fountains made with Phoenix. When I renderer them as particles, everything looks good, Motion Blur is spot on.
The problem arises when I export them as alembic sequence. No Motion Blur at all and I guess it's down to the fact Corona doesn't render Motion Blur with changing topology.
So, my question: is there a way to store the velocity channel (from Phoenix) into an Alembic sequence?

Thanks a lot. :)

[Max] Resolved Feature Requests / Re: Max 2019 Fluids - add rendering mode like Arnold Surface

Just basic features, forget about foam and Motion Blur, which are essentials for a production use of the liquids. :(

Hi all.
Foam and splashes available in Corona are awesome!
I was wondering....does anyone know a workaround to make the wetmap working with Corona?

thanks a lot!

Hi,
it's been mentioned phoenix foam and splashes will be supported on the next daily build.....I was wondering, when are you planning to release it?

I apologize if this has been already requested.

Kindest regards,

I have realized the white spots only appear when rendering within a region......I think this is something it was already mentioned.

Thanks

It's shallow water on top of a glass structure.
I know it's a complex scene to calculate. I have tried with just the water, without any glass underneath and the issue stays the same.
It doesn't seem a material/object related issue.

thanks for your interest.
