Maya 2022 crashes - MASH instancer with StandIns ARNOLD GPU rendering

[Hampf2702YP5UH]

Hi there,

Maya 2022 crashes most times when using MASH instancer with StandIns. But only with Arnold GPU rendering. No imager is added. CPU rendering works fine. Crashing is independent from number of StandIns/Instances or number of distriburted objects.

This is the error message

// Error: [gpu] an error happened during rendering. OptiX error is: Invalid context (Details: Function "_rtContextLaunch2D" caught exception: Validation error: No child set for transform node)

GPU 0 had 22724MB free before rendering started and 18358MB free when crash occurred //

I'm Working with a Nvidia RTX 3090 now, two weeks ago I had exactly the same problems with my old 2080ti.

Arnold MtoA 4.2.3 Arnold Core 6.2.1.1

Nvidia Studio Driver 471.11

Any ideas? Is anybody facing the same issues?

Thanks.

Can you post a simple scene that reproduces the problem?
To attach, rename the file from .ma or mb to .txt

The first file ist the Maya file, the other files are ASS files which are needed for the StandIns.

You must play a little bit in the Arnold Render View and turn on 3D Manipulation. If it's not going to crash increase the number of points in rge MASH distribute node. If it's still not going to crash add the denoiser optix (add imager) in the Arnold render view. Now a crash is for sure.

Another strange behavior is that from time to time the Instancer boxes in the viewport do disapear the visibility button ist still checked (Mash_Instancer). Then you have to press this button deveral times until you can see the boxes in the viewport again.

I think the number of crashed depends from the number of aiStandIns integrated in the Mash network.

Thanks for your help.

Thanks for the files.
I haven't had an Arnold GPU error yet. Currently, I'm up to 100K instances.
Maya has crashed twice, after I closed the Arnold Render View and tried to click stuff while Maya was not responding...
