Is there no need to pre-populate gpu cache since the option is gone now ?

[lee_griggs]

It is not necessary now.

5.6.6 is brutally slowing down my material editor...!

If you use denoisers the Framebuffer has sometimes black frames, no way to use GPU...! CPU is only possible without denoisers. Is there a way to rollback to the previous version of arnold?

Cheers

Multiple problems with the latest arnold, crash after crash in different circumstances.

Easy to roll back - first remove the app with Windows (MaxtoA) and then install the previous one from here:

Thx - after rollback - it´s working again!

Were you able to send CER reports for any crashes?

Which denoiser? OIDN can use the GPU for denoising. What GPU and driver version do you ahve?

[WojtekOgrodnik]

That was the last thing on my mind - urgent job had to be done...
I should be able to replicate easily at some point.
All the crashes were happening on existing scenes, first one when opening standard material editor - instant crash.
Another when using active render and advancing from one frame to another (everything static, only the camera movement was animated).
Another one when batch rendering...
Tried to use different denoisers and rendering without them.
All on GPU.
Gave up and rolled back to get the job done.

[Stephen.Blair]

The GPU denoising with GPU rendering is a known issue. For reference, it's logged as ARNOLD-14560
GPU denoising unable to run while GPU rendering. That's the ticket number to look for in future release notes.

Hi Stephen,

it started when I opened the material editor, 5.6.6.6 unable to use it, roll back to 5.6.5.2 editing was okay, still way slower as scanline,, but okay to work. Rendering in 5.6.6.6 was full of random crashes on gpu and black saved renderframes with both gpu/cpu. In 5.6.5.2 both cpu/gpu FB was fine. This time I saved the files on a local harddrive, so I am not sure if the black frames were saved incorrectly because of the network.

[WojtekOgrodnik]

Noted, but I rendered files that rendered fine in a previous version (and still render fine after rollback). Never had any issues with denoising and rendering (both gpu). Also - never had any issues with arnold render view with denoising and running on gpu - with going between animated frames. This version was crashing.

[WojtekOgrodnik]

Had the same experience - black frames in an animated sequence - saved to local disk.

The Slate Material Editor? I'm not seeing any difference here. What's slowing down? The preview renders?

[rsparwasser]

ME is absolute unusable, neither in node or alternative editor. It’s slow when opening, maybe it’s the calculation of the thumbs. Picking from scene is slow. Any change is slow, Laptop fan is getting crazy 🙂 If you use the colorpicker, the mousecurser will freeze for a second or two after releasing the mousebutton. I have the same on a different pc, so I guess it is not based on hardware.

nothing in 5.6.2.6 ! 

cheers! Arnold is cool!

Ok, I see that 3ds Max QA just logged a bug for this, so they hit the problem too.

Thanks for reporting the issue.

[giuseppe.schiralli]

We identified the cause of the regression, and working on fixing it.

You also may notice that the rendering session is slower to start. Same problem.

There's no workaround for it.

Sorry for the issue.

[ingmar.wittmann]

The latest update is unusable. My latest scene that was working fine with the last version, is now crashing when i open the material editor.  Rendering animations with GPU is not working....
How about testing?
