Hello, just me or does s/px-counter always stay at 0% until completed.
Like, it doesn't advance towards 100%, it just turns from 0% to 100% on completion, even on longer renders.

It does for the denoised passes when the denoiser is set to "denoise on completion". It shows how many samples have been denoised, instead of how many samples have been taken.
Ill check if it can change it so that it behaves the same as the octane gui, where it shows "SamplesShown/SamplesTaken/SampleMax"

Thank you Chris for RTX support , that was fast :-)

Will it be possible to render the new "Grooming Hair" with Niagara Physics in Octane for Unreal ?

Here is a test I did , but Octane does not Render Hair Strands right now , the Unreal Pathtracer did , but it is not as strong as Octane.

Chris - the plugin is really awesome I love what possibilities lie ahead

But the lack of ability to handle opacity mapped textures is a downer....It just kills it.

I know we can do Octane materials, but would be sweet if it could turn it over on the fly automatically.

We try to match the materials as close as possible, sometimes conversion conflicts though and we have to make choices. However I think that water should work, and is probebly a bug.
Are you using a subsurface material for the water? Could you share your material with me? or PM me a screenshot of your material set up? Blend mode/Shading model?

Hi,
I think I have an issue with the Cuda cores in my second graphics card.

I've installed a new graphics card into my system. The main graphics card is a Titan RTX which works fine, it uses all the Cuda cores when rendering. The second one is a Nvidia RTX 2060 Super which doesn't seem to be using the Cuda cores when rendering. Please, some help will be appreciated. I might be doing something wrong.

The second graphics card was installed later, so I don't know if I have to re-install the cuda drivers again?

Thanks in advance

Update:
When turning off RTX acceleration, the second GPU works fine.
