How much memory is available? Look up higher in the Arnold log

00:00:00  1477MB         |  GPU 0: Quadro K2200 @ 1124MHz (compute 5.0) with 4096MB (432MB available)

00:00:00  3085MB  |  GPU 0: GeForce GTX 1070 @ 1746MHz (compute 6.1) with 8192MB (4053MB available)

using default setting,512M

If you restart Maya, do you still get the same error?

If so, can you post a full Arnold log (verbosity level Info) as an attachment? Or send it support@solidangle.com?

Here is the log file.arnold11-gpu-fail.zip

Thanks. Unfortunately that doesn't tell me enough. Maybe you can send me the scene (or ass file). Ideally, a simplified version of it. For example, if you remove most of the geometry, do you still get the error? If so, then send that version.

It seems the "Force Texture Cache Flush After Render" function cause this problem，but I'm not entirely sure. Here is the scene fileGPU_error_ASS

BTW,optix denoiser works sometimes,but if I get the error message,I need to restart maya to try make it work again.

Optix doesn't do a great job at recovering after some errors. Its a known issue and something we're working on trying to improve. For now though, if you get that error message you will need to restart Maya to use the optix denoiser again.

[linzhen369]

Thanks for the reply,I think the biggest issue is sometimes even I restart maya,it still not work.

[Stephen.Blair]

Thanks. It renders and denoises ok with kick on the command line.

Now to try in Maya...

[declan64SRL]

It seems like to me optix isn't being initialized correctly for some reason. Could you try selecting you GPU manually and seeing if that works.

Render settings -> System -> tick the "Enable Manual Device Selection" and select your GPU

[Stephen.Blair]

It renders and denoised ok in Maya too.

I don't use Force Texture Cache Flush After Render, because that was for the Maya Render View, not the Arnold Render View.

[linzhen369]

OK,I will do some test later.thank you for doing this.

[linzhen369]

Yes,I'll try it later,thanks.
