Arnold Procedural rendering display issue.

[66175545]

Please tell me, while rendering with Arnold Procedural, I found that Arnold Procedural can't adapt itself to undulating planes, such as terrain. Is there a way to solve this problem? Another problem is that Arnold Procedural is particularly unstable, crashing 8 out of 10 times in the test, which defeats the purpose of it (fast and resource-saving).

The shapes inside the procedural are raised by 45 cm. You can see that in the viewport by looking at the procedural. The bounds are above the pivot point of the object.

Or if you open the ASS file in a text editor, you can see that the matrix of the meshes have 0.448 in the Y axis.

 matrix
 1 0 -0 0
 0 1 -0 0
 -0 -0 1 0
 0 0.448663324 -0 1 

Attached a modified ASS file, where the meshes are placed in the origin.

About the crashes, does it crash in the IPR window, when you change settings of the Arnold Scatter? Can you reproduce the crash with some simple steps? So far I could not make your scene crash.

Your test scene renders on the GPU, does it also crash when you render with CPU?

Thank you very much for your careful reply, it was an oversight on my part, thanks.

I wonder if it has anything to do with video card memory? My graphics card is an 8G 3070, 64G of RAM , CPU i9, sorry I can't test this at the moment, I just wanted to give feedback on the problem I'm having. Thus bettering the Arnold experience.

Could be if you render many instances on the GPU. If you set the log level to Debug in Arnold Render Settings > Diagnostics, you should see the memory usage in the log.

Ok, I see, thank you very much for your careful reply.
