Hello, based on my testing, the plugin doesn’t seem very friendly with Arnold.
When using thumbnails, specifying the use of the Arnold renderer always fails.
Is this the case?

Hello

 Arnold renderer always fails

What is mean “fails”?
What version of 3ds max and Project Manager are you using?
Could you please describe more about the problem?

When rendering Arnold material thumbnails, instead of generating sphere thumbnails, flat, solid-color thumbnails are produced. With ‘use custom studio’ enabled, and only an Arnold area light used while specifying Arnold to render the model thumbnail, only a flat black image is generated (using default lights or V-Ray area lights works normally). These issues do not occur when I specify V-Ray as the renderer. The software I used for testing is 3ds Max 2025 with Arnold 5.7.8.0 and 3ds Max 2023 with Arnold 5.7.7.0. The plugin version is 3.37.86.
