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.

Please try version 3.37.90
Thanks for your feedback.

Thank you very much for your proactive improvements. Your team has done a great job. After my initial testing, the material thumbnails work fine after rendering the specified Arnold rendering thumbnails. However, the model thumbnails still don’t work very well. I will conduct more tests later. The testing software is 3ds Max 2025, Arnold 5.7.8.0, and the plugin version is 3.37.90.

Try version 3.37.91
Please note that if textures are not found, you may also get black renders. In some cases, relative paths will also not be accepted as valid.

The plugin has been updated to 3.37.91, and there are no more errors. Thank you very much for your team’s efforts, you’re doing a great job.
