Max 2023 + Vray 6+ RC
« on: August 05, 2022, 06:21:08 AM »
Whenever we add a RC object to our scene it renders fine locally. When we submit it to the render farm using RP Manager and Deadline it fails to render. Something is happening were RC doesn't allow for rendering with Deadline.

What Deadline version do you use ? What error did you get ? If possible, please post a screenshot.

Thanks.

If that helps, i did a quick test here, using latest Deadline (10.1.23.6), RailClone 5.2.6 and V-Ray 6, and it renders without problems.

Currently using 10.1.22.5. Didn't realize a new version of Deadline was out. Let me see if that fixes it.

So something still isn't right. Created a test scene on my machine with teapots and Vray6. Renders fine locally. Submitted to Deadline and renders fine. Add FP and or RC to scene. Render locally inside 3ds Max renders fine. If I submit to deadline and have the render farm try and load the scene to render and fails to "load file". I even submitted from my machine and turned my machine on to render via deadline. Scene fails to load even though it renders fine directly inside of 3ds Max 2023 on my machine. I have updated all of our plugins to the latest versions of Vray, RC, FP and Deadline that is currently out.

Thanks,
Austin Reed

Please,  try this:

- Open your scene locally.
- Open Rendering->"Scene Converter".
- Select in "Current Preset": "RemoveInvalidLegacyElements"
- Click "Convert Scene" and save.
- Submit it to Deadline.

It seems problem is caused by an old Mental Ray material plugin, which was added automatically to scenes by previous Max versions.
It was removed from Max when Mental Ray was deprecated, but old scenes and materials may include it yet. In this case, it was added to the scene by the materials used by FP and RC presets.

For some reason, scene loads fine in Max 2023 locally, but Deadline detects the issue and triggers an error. I could find it in the render node logs:

Code: [Select]
2022-08-09 10:06:10:  2022/08/09 10:06:06 WRN: [19832] [22748] Missing dll: mrMaterialAttribs.gup - mental ray: material custom attribute
I could reproduce the problem in a scene without FP and RC (collapsing them to a mesh).

I would suggest you report this issue to the Deadline support. Probably they can fix it.

This was definitely the cause of our pain! Thanks for the help on this :). Do you plan on removing Mental Ray materials from your library assets moving forward?

I'm glad the problem is solved.

In the past we considered to remove this gup from our scenes.
But that would require to upgrade the files to a recent Max version (2018 or above), breaking the compatibility for customers who use old versions.
