Firefly Filter 50, 25 and finally 10. All the time better and render times are just the same - 6 sec / frm.
Next to test is the Denoising, I lowered it from 0.3 to 0.15
No visible difference at all. So I keep it 0.3 since the more you have it ( smaller number) the more it eats out skin details…
Now I bring in motion blur.
First 30 samples / 5 motion blur sub frames:
Totally noise free and crisp clear, but 3 x rendering time.
I lowered the samples from 30 to 20 so it rendered 1/3 faster.
But I see some noise at the hair…
From this on I am shooting at the dark. If you have any ideas please share them here? I can also send you the scene as PM.
I made small changes just by hunch.
First I lowered the path tracing / max bounces from default 4 to 3.
I cannot see any visible change in quality, at least with this shot where I have just one distant light and no white floor etc. to bounce from.
I also raised the Samples per pixel per iteration from 3 to 5.
I hope this helps with the noise at hair…
Unfortunately, raising the Samples per pixel per iteration to 5 or even to 10 is not helping at all, it gives more noise…
So back to 3 with that on the next test :P
Samples per pixel per iteration back at 3.
I tried to drop the motion blur subframes to 3. No good, noise at hair:
Motion blur back to 5.
Render time 9 sec / frm.
Now we a re good BUT the reflection in the eye is pretty bad.
FireFly from 10 to 1.
No help for the eye reflection noise…
So back to 10 with next test…
So this far I made it myself. Now I would love to get so help from gurus. How to fix the eye reflection issue? How about blurring the reflection of bright noisy light with Roughness settings of the eye material?
I tried with Denoising 0 (max) but it did not solve the noise on eye reflection, and its also a poor solution to max this out since we loose so much of the skin detail.
Back to 0.3 with Denoising. Now I really need your thoughts :)
Please increase the total number of samples to 256 and set the denoiser weight to 0.2. This will increase your render time, but I’m curious to see the result.
I used 50, since 50 samples x 5 motion blur = 250 total samples, or did you meant something else here?
I think you did since this one did not solved the noise on eye but it blew the rendertime :D
Here is the roughness reflection idea.
The ball have default OmniPBR surface with Reflactivity / Roughness 0.25
Totally noise free.
If we could have this kinda soft reflections on eyes, it could be some kind of a solution…
roughness map influence is missing with this. I cannot tweak that.
I found the setting from CC4. But the roughness I setup there is not effective in Omniverse.
Here is the video showing this:
In the end there is visible that there is 2 different reflections of the light. Even if I raise the roughness from material setting the other reflection stay sharp…
Thank you for sharing this detailed experience. I’d like to share my experiences and its result as my settings with you.
My graphic card is RTX 3060 (12.1GB) so I can’t increase some settings because of rendering time. I wait mostly 100-120 hours rendering time for almost 11.000-15.000 frames but the result is ok for me.
Please look at that, maybe it will be useful for you.
For Path Tracing Mode
Frame rate: 60FPS
Sample per pixel:20
Path Trace Sample:10
Enabled motion blur
for the lightning:
Outside: Noon_Grass environment and intensity mostly between 1200 - 1400 for outside
Inside: Rectangle light, intensity 800-1000
When I use these settings, I have almost satisfied results with my Graphic card.
If you didn’t try these settings before, please try.Regards
