[Max] General Discussion / Re: Single vs DR render passes

« on: Yesterday at 12:29:00 »

Hi,

We would like to investigate this issue further.

Can you please send us a ticket along with your scene and some repro steps?

Hi, just made the ticket.

[Max] Bug Reporting / Re: Very slow geometry phase 10x slower than old pc

I am also checking on this. It is crucial to get info on whether dual CPU systems will be better optimized or not.

Here is a sample of this issue. DR at higher passes numbers has double the amount of noise compared to a single render.

Hi Tom, all nodes have the same hardware, except a dual CPU, but that one is never the master. We`ve set the sync interval to 90 sec. Everything lower messes the nodes when rendering 6k renders. Approx. each node does 1-2 passes in 90 seconds, so it`s not 20-30, which would result in a higher pass cumulative count after each sync interval. Nodes/master are separate from the day-to-day work and only render one render at a time. This is something that has been happening for a while now, and we use DR only when we are in a hurry to render 1-2 6k render due to this issue. It would be great to hear exp. for other forum members who use DR.

[Max] General Discussion / Single vs DR render passes

« on: 2024-05-16, 15:35:55 »

Hi, I`ve wanted to ask this for a while now. When rendering an image to 3% noise, a single machine render takes around 60 passes in 6k resolution, but for a DR-rendered image with eight slaves, it takes more than 200 passes to reach 3% noise. This is not isolated case, it happens in all situations/3d environment. Is this a known fact?

Thanks,
Hrvoje

[Max] General Discussion / Re: UHD Precomputation for multiple cameras

« on: 2024-04-10, 13:27:24 »

You can use a single cache for multiple cameras. The only risk is that the quality of the cache generated from camera A will be a little bit worse than if it would be generated for camera B, but that should not be any major issue. It should not cause any rendering slowdown or other problems.

Since you mentioned sea waves, if it's an exterior scene (like a beach) without interior elements or areas illuminated by strong GI, maybe the best solution would be to use path tracing as both the primary and the secondary solver? The UHD cache is mostly useful for interiors.

Thanks, will try that for the next animation. We made a hdcache for each camera in the end since we were in a hurry. Thanks!

No one? Devs?

Hi all, this might be a noobish question, but we are about to render a big resolution, so we want to make sure we do everything correctly. Is it possible to use the same HDCache file for multiple cameras of an exterior animation with only moving people and sea waves, or do we need to make an HDCache for each camera independently?

Hardware / Re: Dual Epyc 9654 experience?

« on: 2024-03-14, 11:11:15 »

Hi maru, yes we can share this scene, but it happens in all the project i am working on, tested this on 20+ different projects/3dsmax files and in every case it is the same: the geometry phase takes 10 x longer? also compared this with a friend (ryzen 5900x) and his geometry phase was arround 12 x faster (same scenes/projects, tested this with over 10 diff max files) so share?

It would be great to sort it out, and it would help others decide whether to go with 9654/9754. Can you please share the scene with Maru to sort it out?

Yes please, even a simple scene is better than no scene.

Maru, any news on this?

Hardware / Dual Epyc 9654 experience?

« on: 2024-01-16, 10:03:52 »

Hi, Is anyone here running a dual Epyc Genoa system, preferably 9654 or 9754`s? I wonder if the scale is better than with EPYC 7702`s 1 CPU vs. 2 CPU systems.

[Max] General Discussion / Re: Corona 10 - Corona Render Assets loading very slow

« on: 2023-10-25, 16:03:06 »

Will this be incorporated into a new 10 hotfix?

Does it work better for you in V11 dailies?
We won't be releasing any new V10 hotfixes as V11 is planned to be released in about 1 month. :)

We can`t really test dailies due to current office workflow, but this is a major issue.

[Max] Bug Reporting / Re: CPU/thread performance drop with Corona Triplanar

« on: 2023-09-25, 13:31:05 »

It's been a while but we have just released a new daily build of Corona 11 with a fix for Triplanar map performance issues. You can find it here:
https://forum.corona-renderer.com/index.php?topic=40442.msg217142#msg217142
 
Please test it and share your results with us.

Will there be a hotfix for C10 with this applied?

Reverted to 9.3, everything works normally. Render nodes are all single and dual 7742 epycs, performance dropped to roughly 25%. Scenes have triplanar maps, all are cleaned with sini forensic so no errors.
