[Max] General Discussion / Re: Corona 12 a lot slower on old scenes

« on: 2024-07-17, 12:48:42 »

Update:
Like suggested, I merged in the "old" corona 11 into a brandnew scene and setup corona12.
The rendering times went down indeed. We now have:

scene 1:
Corona11: 27:21 min
Corona12: 40:16 min
Corona12 (new file): 36:37 min

scene 2:
Corona11: 6:25 min
Corona12: 7:30 min
Corona12 (new file): 6:40 min

It renders faster now compared to just open the old file.
However, we are still a lot slower than corona 11.

Any more suggestions?

You are getting different rays/s values indeed. This may be a silly question, but are you sure it is not related to thermal throttling? There is currently a heatwave in a lot of countries.
If not, then we would be interested in checking your scenes: https://support.chaos.com/hc/en-us/requests/new

.
Workstation is watercooled and CPU temps never ever go above 65°C.

Could you try to reset render setup and re-create it as faithfully as you can? It's possible that some settings got corrupted when loading a scene created in previous version and now it negatively impacts render speed. I didn't compared Corona 11 vs 12, but i did quick comparison to Corona 9 recently and the latest version was significantly faster.

Will give this a try tomorrow and report it.
To be sure, I will merge it all into a new blank scene.

[Max] General Discussion / Corona 12 a lot slower on old scenes

Hi everyone,

we just upgraded to corona 12 and did some test renders with projects from this year, all done with corona 11.
What we noticed is a huge increase in rendertimes, when rendering with corona12!

scene 1:
corona11: 27:21 min
corona12: 40:16 min

scene 2:
corona11: 6:25 min
corona12: 7:30 min

scene 3:
corona11: 4:40 min
corona12: 7:29 min

This basicly happens with every scene we open. All tests are done on the same PC (Threadripper 3970x), with same rendersettings.
Did anything changed from corona 11 to corona 12, so that old scenes need to be adjusted ?

Attachted are two screenshots. (had to blur the image, sorry)

Any help is greatly appriciated, because this increases are huge!

Thank you
Markus

On Chaos Scans, a Chaos Scans license is a Chaos Scans license and not tied to a particular render engine - this means if you own a Scans license from V-Ray Premium, it will work with Corona, and if you own a Scans license from Corona Premium, it will work with V-Ray. Same with Phoenix, and Player :)

Thats good to know. However, a corona/vray bundle would be nice, as I think, there people like me, who own and use both.
Also, as I wrote above, a unified CHAOS RENDERNODE would be good, but I know, you would make less money :-P

The biggest bummer is, that you now have to pay for rendnodes.

Corona WS + 5 Rendernodes was 349,- . Now it is Corona Solo (322,80 ) plus 538,80 for the rendernodes. Thats an increase from 349,- to 861,60! Or did I missed something. ( I am not talking about the granted offer for longerterm user).

As Corona and Vray is one family, I really hoped, that AT LEAST, when I have to pay for rendernodes now, the rendernodes are usable for corona AND vray !!!

And as Benny said, do we get any bundles vray/corona, as with the premium versions, we have to pay twice for some products ?

Or does the corona Chaos Scans gives access to the vray Chaos Scans too?

Lots if unanswered questions in my eyes.....

[Max] Daily Builds / Re: New Corona Physical Material (PBR) playground!

« on: 2021-06-23, 15:32:14 »

Hi

i am wondering, why isnt the corona converter converting the 3dsmax Physical Material to a Corona Physical Material ? These materials get skipped.

Also is it possible to convert a Corona Physical Material back to a legacy one for backwards compatible reasong? That would be really good. I know you would loose some feature...

[Max] I need help! / Lots and lots of white blotches with new caustics

« on: 2019-07-25, 10:38:35 »

Hi guys,

i have an issue with the new caustics, getting tons of bright blotches in my rendering (see attachment).
I dont use any refractions caustics in the scene. Also the "Generate caustics from environment" is unchecked.
There is no HDRI used, which could have bad exposure.

Did anyone encounter something similar? As there are not really any parameters to tweak the caustics, I am a bit out of options :(

Thanks for any help
Markus

I know it has been a while since something was posted here. But what is the status on IR with DR?
Is this still something you are investigating or did you dropped the idea completely?
