Arnold 5.3 - GPUs not detected

Just downloaded and installed the new Arnold 5.3. I wanted to test the GPU rendering beta feature, though for some reasons it does not detect my graphics cards (see picture attached).

Could it be a drivers issue? Maybe I need the latest ones installed?

Thanks in advance!

One more thing.

No need to wait for the content creator drivers for the GTX cards.

I am using the GPU render with my GTX Titan X at home (I have three of them), driver version 419.35.

OK! Got it to work as well, just that a lot of features are not supported on GPU, yet.

@Jp Varen There's no Arnold GPU on macOS. Arnold GPU uses Optix 6, and there's no Optix 6 on macOS. So Arnold 5.3 for macOS does not include any GPU rendering code.

@Pietro Di Nicola Please ask a new question. This question was about MtoA and the drivers not showing up (no error messages). MAXtoA is different has its own specific issues, especially with locale if you are not using the English locale and the decimal separator

Sorted!

It was the AreaLight, which is not supported in GPU mode. As soon as I added a skyDome Light I got the scene rendered properly. :-)

Well, I hope that after the beta we'll have the area lights supported.

Okay, now I am at the point where I have managed to make everything start the way is supposed to.

I have enabled the adaptive sampling, as suggested in the documentation, set the values as advised and Pre-Populated the GPU caches.

The render view starts the render process without complaining and without warnings, which is good.

Unfortunately said window remains black the whole time, no matter what I do. Actually when I change things (again, exposure, light intensity and so forth) I get this warning: "Warning: [gpu] closest_filter ("_renderViewDefault@closest_filter") not supported on the GPU".

That warning makes no sense at all, because I have set the filter on "Box", not even Gaussian, let alone "Closest".

I am officially out of options.

@Mauro Sanna That warning is because the Render view has a special AOV it used for object selection, and that aov uses an unsupported filter. You can ignore the warning, it won't affect the actual render

@Stephen Blair

There are no AOVs active at all. I get the warning no matter what. That's fine, it's just a warning after all.

@Mauro Sanna It's a hidden AOV that the Arnold Render View uses. You won't see it in the list.

I have the latest driver and now it detects the two Quadro M5000 cards.

Unfortunately as soon as I launch the interactive GPU render I receive different error messages, depending on its mood. This is the most common one:"GPU render stopped because a previous error".

What previous error it is talking about God only knows.

Also sometimes it freezes Maya for a bunch of seconds and then it crashes the whole app.

Then there are times where I only get this warning (which is just a warning, so nothing problematic in Maya universe):"Warning: NVLink is not enabled on all selected GPUs, ray and hit stats are disabled".

Also sometimes I manage to make the render view start... Something... Though I only get a black screen and nothing changes, whatever I change (exposure, intensity of the light, even on a simple scene made of just a sphere, a plane and an area light).

Not a great start if you ask me.

Do you have the right driver, like Stephen showed you ?

If you have a GTX 900 card, the driver is not out yet, you'll have to wait a few days.
