Brecht Van Lommel (brecht) added a comment to T53038: Principled shader clearcoat roughness inconsistent change from 0.0177 to 0.0178..

Right, the fixed 0.25 roughness is definitely a hack, hopefully we can get rid of that too.

Pascal Schön (VanCantus) added a comment to T53038: Principled shader clearcoat roughness inconsistent change from 0.0177 to 0.0178..

Maybe also the fixed roughness of 0.25 for the G term can cause some issues. Disney didn't really say in their paper from 2012 what the purpose of this hack was, but only that it's "found to be plausible and artistically pleasing". I will try at first to change only the D term to GGX without changing the G term (which means keeping the 0.25 roughness here) and look if this causes more problems and if so, I think we should go with having a consistent roughness throughout the whole clearcoat calculation. By doing so, we wouldn't need to have a distinction between clearcoat and non-clearcoat in the Microfacet BSDF anymore.

@Brecht Van Lommel (brecht), yes, I see this like you do. I don't think that we get a real benefit out of the GTR1 distribution. The difference (especially because clearcoat is only applied with a pre-factor of 0.25) should be pretty low and can thus be neglected. For me it seems ok to switch to GGX, but I will at first try to compare both versions today before adding a patch.

rob (blenderpedia) added a comment to T53068: AMD Threadripper not working well with Blender .

@Brecht Van Lommel (brecht), we don't have threadripper at the studio, only Ryzen 7 1800X.

Some other questions / ideas to troubleshoot the issue:

  • Make sure all Windows updates are installed.
  • Disable any possible power saving setting in BIOS.
  • Disable any possible power saving settings in Windows itself.
  • Disable HyperThreading.
  • Check whether Blender detects proper number of CPU threads.
  • Get Ubuntu LiveCD and see if there will be a performance issue on Linux.

@Sergey Sharybin (sergey), is there a machine with a CPU like this in the Blender Institute?

rob (blenderpedia) added a comment to T53068: AMD Threadripper not working well with Blender .

The first time i tried to render the scene was unpacked. After hanging for hours i started using all the benchmark files on the blender website and comparing this with my intel system. On this point i saw a significant difference between the threadripper and my intel sytem. Not on the small ones like the BMW, classroom, but the production benchmark and my own scenes. In my opinion most of the threadripper tests where done on these scenes, and not large scale RAM scenes.

@Brecht Van Lommel (brecht) I'm not sure he did the OpenMP test as you described.
The video showed him changing threads in the UI as opposed to a command line command. Is that the same?
Rob, can you verify that you ran this in command line?

Intresting result when doing a blender internal benchmark test. I used an 11 GB ram scene on my 4770K and threadripper workstations.

@Joel Godin (FloridaJo), the GPU is not involved in the synchronizing objects stage, so I doubt it's causing issues here.

It doesn't look like it's the CPU.
You may want to see if it is a GPU bottleneck.
GPUview is the tool for that, a description of it is here;

Which parts of the render are slow? The video shows just the synchronizing objects stage, is BVH build slow too, and path tracing?

Hello Rob.
Can you go to this page and follow the instructions for installing the Microsoft Process Explorer

Indeed, please explain clearly what you mean by "not working" and provide us steps to redo the probmem. Does it crash, does it not save the file, does it render black, .. ? Does it happen with the default scene or only a specific .blend you are working on, etc. Are you using the GPU or CPU for rendering?

Thank you very much, Vuk. Just tried it and it works. This should get me by while I save up for a new GPU. The main thing I need is the viewport render preview which I use a lot and the CPU is just not fast enough.
