Arnold Sky lags big in C4DR25 and C4D2023

[Kidmograph]

Hi there, I'm working with the Arnold Sky (Physical Sky) and I can barely select the tabs to manipulate the values.

It hangs each time I click a tab for about 5-8 seconds (mainly the MAIN tab)

I noticed this lag in the last 2 updates.

I'm using C4DtoA 4.4.0 and using CPU as I'm working with Toon shader.

Any help is very much appreciated. 

Thanks

Only physical sky, nothing else slows things down?

Can you get an Info-level Arnold log for some IPR rendering, so we check that?

[Kidmograph]

Thank you Stephen.

Yes, only the Physical Sky. No matter what other object I select, when I select it back it keeps hanging. The console don't show any errors, where I can get more info?

If you're rendering, then an Arnold Info-level log should show something (not necessarily errors, just information and progress...). The verbosity level is in Render Settings > Diagnostics, and the log goes the Extensions > Console

What if you disable the material and shader previews? (Preferences > Renderer > Arnold)

Tried to save a log and a text file and they're empty. Also the console won't show any activity. Please find the attached screenshot. Sorry for the noob issues here. I can make a file collect and send it to you. Thank you.

Just to clarify, this lag happens when you select the Arnold Sky object, before displaying its attributes in the Attribute Manager, right? Even if no render is running.

Had a similar report recently, but was not able to reproduce it.

Hi Peter. Yes. This big lag only happens while selecting the "main" tab on the physical sky. Not even using the IPR, just selecting the tab. It's a lag of about 10 seconds! very strange and really makes my workflow super slow. Happy to share the project, but it's indistinct.

Also I wanted to roll back to previous versions but there is not an update available for C4D 2023?

Thank you in advance.

Unfortunately not, 4.4.0 was the first one supporting C4D 2023. Hopefully I can figure out soon what's going on and fix it in a next release.

[Kidmograph]

Alright, thanks. How about C4D R25? Is there a way to get an installer at least 2 version older?

Sure, previous installers are here: https://arnoldrenderer.com/download/archive/

Actually it would be interesting to know which version introduced this problem.

[Kidmograph]

Thank you. Somehow didn't find them yesterday.

I will try to go back a few and see what version started with this issue.

[peter_horvath]

I've been able to track the issue down and fix it. It will be available in the next bugfix release, soon.

[Kidmograph]

Oh really? That's amazing to hear, thank you so much! Looking forward to it!

The fix has been released in C4DtoA 4.4.0.1. Please give it a try and let me know if it works as expected now.

[Kidmograph]

Will do it right away. Thanks!!

[Kidmograph]

This works great. Thank you so much Peter for your hard and fast work!
