Hello World: OctaneRender 4 is here

[vijay]

Could you please a quick test to eliminate out of memory error?. Set the resolution to 4 x 4(denoiser usage will be less than 10 MB) in the film settings node and then enable denoiser. We do handle when denoiser can't allocate memory, so ideally it shouldn't be crashing but just logs an error message.

nope, still crashing yet.

I have sent you a PM for figuring out the issue. If you could do it, that would be much appreciated.

What is minimum samples recommended before denoiser is enabled to get clean, sharp and detailed image and not blurred our by the denoiser ?
Also will Adaptive Sampling work with denoiser?

Thanks

I did some tests with v4 yesterday and am posting a file for review. It includes different settings and speed comparisons with 3.08.

I readily admit that I didn't ensure equivalency of settings beyond the samples...and that certainly could have a big difference. Obviously v4 is currently a very early build and hasn't been tuned. Also this is just one sample...different scenes could yield dramatically different conclusions.

A few observations...again with lots of caveats:
- 3.08 was much faster in my tests. Over twice as fast in one test.
- The denoiser is promising but it doesn't seem to remove all noise and doesn't seem to have any impact on fire-flies.

Yes, it works with Adaptive Sampling. I don't think there is a min recommended number of samples. This would depend entirely on your scene, how many and what type of materials (SSS, displacements, glossiness etc.), textures, number of lights/polygon emitters... etc etc. Just like before, only you can get a cleaner image much quicker.

I think there still needs to be a lot of various training scenes fed into the AI to learn from, it will continue to get better over time. Performance and VRAM usage will apparently be looked at and profiled.

Try to set the Blend option to 0.3-0.5 and set the minimum to 1000 at least.. you can decide the amount of Denoising withthe Blend Otion and use HIgh res textures for a cleaner and sharp result always

There is no difference in waiting for 1000 samples on min 10 or setting it to min 1000 afaik. I think the end result is the same, the only difference being that there is no time spent on denoising until the threshold is reached, then interval updates kick in. (I may stand corrected)

There must be a reason why they put it there then, frankly all these 60-100 samples denoise test are way too far from reality but the interval is to tell octane how long it has to wait on every denoise which I don't actually get why.. you can see the voice 'rendering' changing to denoise each 20 sec or the interval set

Sorry, but every time I enable AI Denoising OCTANE crashes.
Even with benchmark scenes.

Which GPU driver do you use for this version?

I've got 1080Ti + 2x1070.

Hopefully denoiser wont create flickering in animations since every frame it can denoise a bit differently .

thanks this is a great comparison. Looks like it is cleaning pretty well octane weakest points like DOF in glossy reflections
