CPU/thread performance drop with Corona Triplanar

[pokoy]

Same here - won't switch until v10 is good to go without headaches.

We'll have to wait til we know we have a working fix before we decide on hotfix or not :) Once it's out, tested, proven to work and cause no problems, we'll then be in a position to decide what to do with it.

We are also having a lot of rendering speed problems with  10.1. Will files be affected in any way if we revert to 9.3?

Depends on what was used in the scene, if it is anything new in Corona 10, then reverting will not give the same results. For our information while we investigate possible performance issues, what is the hardware configuration of the machine(s) experiencing problems? Also, is the Triplanar map used a lot in those scenes that are having issues? Thanks!

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.

TY for the info!

Hi,

I also have the same issue happening. Interestingly, it happens even when the object is not isolated.

I started this thread: https://forum.corona-renderer.com/index.php?topic=40872

Until the devs fix this, try setting blending to 0 in corona triplanar.

I currently work on a simple with a single Triplanar map with Blending Amount set to 0.0 but the rendering uses only 60% cpu power.
The only fix I found to have 100% cpu usage is to totally getting rid of the Triplanar map.

I noticed the same thing the other day.

The same problem here.
I have very simple scene where wall material has CoronaTriplanar. If it's on then I have ~60% of cpu usage. When off then it's 100%. Blending value doesn't change anything. I tried 0,0 and 0,5.

Are you able to send over a scene? Instructions on how to do this can be found in my signature.

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:

Please test it and share your results with us.

Now it works like a charm :)

That's great to hear, thank you! If you notice anything unexpected, please do let us know.

Hello corona team,

I want to ask the same question as @alexyork did in my thread about chaos scatter:

Would the devs consider pretty clear bug fixes like this as something you can roll out into a Corona 10 hotfix? New features and tools certainly make total sense pushing into dailies, but if something's found to be a bug and doesn't conflict/require anything new from a daily/new core then it would be a huge benefit bringing it to the current version of Corona instead of having to push into dailies/full new version (which takes time to be released, tested, HF released etc.). It'll be a looong time before we're moving to Corona 11 final + HF, presumably, since C10's only just been released.

would it possible ?

Best regards

Will there be a hotfix for C10 with this applied?
