Arnold Render Settings Dialog Malfunctioning

[dhardy21]

I installed Maya 2024.1 which came with MtoA 5.3.2. Whenever I'd like to change the render settings, the options appear squished and therefore inaccessible.

 MtoA 5.3.2 Squished 

I tried updating Arnold to 5.3.3.1 and Arnold would not load.

Render settings window without ArnoldLog after updating to 5.3.3.1

I've also tested loading in some 3rd party renderers and there are no issues.

This issue also happens in Maya 2022.

I've tried uninstalling and reinstalling Maya 2022, Maya 2024, and Arnold multiple times on different computers.

All tests were done in Windows 11.

Does it happen with new Prefs?

[dhardy21]

Yup, I deleted my prefs and the issue still persists.

MtoA is loaded in the plugin manager? What does it say in the script editor when you try to load it?

When using 2024.1 and MtoA 5.3.2, here is the console output:

Arnold creates all of the shelf menus when using this combo. The only issue with this configuration are the squished render settings.

What error does it give when you try to load 5.3.3.1 in the plugin manager?

Here is the output when I try to load MtoA via the pulgin manager:

[thiago.ize · Accepted solution]

The log messages you are posting all show that it's loading the ai.dll (the arnold library) from your htoa installation instead if your mtoa install. The htoa installation has a different version of Arnold than what mtoa libraries expect and so it fails.

Thanks Thiago!
