Render stuck on 100% C4D Octane PMC Tweet

[HOLYSABRE]

I was attempting to render a simple scene using 4048 samples on PMC, but the render would stay stuck on 100% on the Render to Picture Viewer. I attempted to render the same scene on Path Tracing and it completed using same amount of samples no problem but when I attempt to do it with PMC again it stayed at 100%
I figured maybe id give it some time and it will complete, but no. It reached 100% within id say an hour at the most so i let it run for another 2hrs and nothing, still stuck.
Any info would be great on how to fix this, for the scene looks a lot better in PMC. <3

PS: Found out what the problem was, I was using denoiser with PMC. Denoiser doesnt work with PMC. Someone correct me if im wrong.

I can confirm this is true. If denoiser is active PMC render gets stuck at 100% screenshots attached.

I thought I'd leave this here as info for others

AI Denoiser does not work with PMC, please switch to Path Tracing.

HI Guys,

First post here but need some help. I am having the same problem, the render reaches the number of passes but then doesnt go to the next frame. Any advice please?

I tried in standalone,C4D and C4D network rendering. Using direct or path tracing, denoising on or off.

Any help would be appreciated.
Thank you
Karl

Hi Karl,
without screenshots and logs is quite difficult to help.

Please share some screenshots of your settings and Live View, then go to c4d menu Script or Extensions/Console, (Shift+F10), and share a complete screenshot of the panel, thanks.

Thank you for the quick reply Beppe,

I have attached the screenshots you needed. The issue of rendering to 100% and then staying there happens on the single machine and also when networked. Thank you in advance.

I couldnt figure out how to add the images... SO here is the link https://we.tl/t-fhO9WhfPcG
Thank you

Hi,
you need to disable AI Denoiser, unfortunately it is not supported with new Ampere RTX 30X0 GPUs in 2020.1.5 SDK, due to an issue with cuDNN library.

The devs are working on new plugins versions based on 2020.2 SDK, and will be published as soon as possible.

Since it is a completely new version, with a lot of new features, it will need a little bit more time than an usual update.

In the meantime, if you need to render with AI Denoiser active, you should need to use a 2020.1.5 plugin, to export your scene to Standalone 2020.2-RC4 in .orbx format and render from there, with AI Denoiser active:

Hi Beppe

Thank you for letting me now. Hopefully 2020.2 plugin will be released soon. I couldnt find 'Standalone 2020.2-RC4' on the downloads page and the link you referred to doesnt work?

I am using the Enterprise version on the main AMD64c 2x RTX3090 and have 3 machines with dual RTX 2080ti as enterprise slaves. Would you advise for the time being only using the 3 pcs and excluding the main one to network render? Or is there a link for Standalone 2020.2-RC4?

Thank you
Karl

Hi Karl,
2020.2 is in RC(release candidate) state, so it is not available from the Downloads section, only stable versions are published there.
You need to download both Standalone and Render-Node installers from 2020.2-RC4 release note discussion:

I had the same problem using PT and the C4D Stage object. The first frame rendered and finished fine but from there on the renders stuck at 100% and wont save the passes. The clock kept running and nothing happened. Turning off the stage object solved the problem.
