Reducing render times by 92%! Denoiser showdown

Blender tutorial showing you how denoisers like Nvidia's Optix can reduce your rendertimes.

EDIT: Since recording, Blender 2.9 was released with denoising included in the default installation (no need to install anything extra), and it supports all hardware! Find it in Render Panel: Sampling: Denoising. Optix (faster) is for compatible Nvidia cards only and OpenImageDenoise (slower) works with any CPU.

Since the recording Blender 2.9 was released with the denoising shown in this video included in the default installation (no need to install anything extra), and it supports all hardware! Find it in Render Panel: Sampling: Denoising. Optix (faster) is for compatible Nvidia cards only and OpenImageDenoise (slower) works with any CPU. Have fun ;)

And with blender 2.81's AI denoise node (intel's openimagedenoise based) we're all saved!!! Great work as always :)

[blenderguru]

Since recording this video, some big news was announced:
1. Optix Denoiser might actually make it's way into Blender officially, removing the need for an addon. (nice!)

watched this video in 2x to make rendering 6272% faster

After denoising, don't forget the filmgrain.

I'm not even an animator or artist, I have never used Blender in my life. But I seem to always watch videos of yours that I come across. You do a great job at making me interested in changing career paths into this industry.

Man, I just read your "This week in 3D" mail for this week... That donut looks insane! I began to learn how to use Blender with your first blender tutorial and I haven´t even downloaded 2.8 yet because I want to do it when your new tutorial comes out! Thank you so much for making this videos free for us :D <3

This is an incredibly well timed video for me, as I was literally today and yesterday trying to fight blender's denoiser to not destroy textures. Now I have some new strategies to try. Thanks!

Someday it'll be nice to get back to Cycles, but for now, I'm loving the 2-6 second render times with EEVEE.

Nice! I immediately thought of the trail neat photo denoiser I've used, didn't know they had one for video as well. Also had no idea how good it really is as far as denoisers go

[lukeswain]

+1 for Neat Video plugin. This plugin is simply the best on the market right now. We were able to render 12+ animations via Octane, and with the samples down to as low as 1500 in some shots.

Then a quick denoise, and it was like we had rendered at 25k.

Finally! My laptop has been struggling with renders even though it is pretty good. Denoising is so bad, I couldn't fix those marks, so I had to use huge amounts of samples. And my laptop was burning.

[mohsh]

Blender 2.81 will have INTEL's denoiser. It's supposed to be better than Optix.

Man, what a lot of work to present the the edited comparison content in this video! Hugely impressive.

[davekite]

Thanks! - That's a really great look at denoising - it's good to hear the ups and downs (so much of AI raytracing tech is sales talk these days). Also good to hear the comparisons you've mentioned - it'll be fascinating to see how this all settles in few years (to think I used to ray trace on workstations 20+ years ago and we'd wait the night a basic image... ! )

[JackLe]

5:11 your hear grew considerably through that little transition there.

[MultiMirs]

What's amazing is that you can use the denoise node in the compositor not just for 3d renders but for 2D Real Life Images too! :O

[karagosi]

Thanks so much Andrew i used almost three days to render single animation with duration of 13 seconds for my Youtube channel, this trick is all i wanted. Can't wait to use them for my next videos.

[alexisprojects]

I appreciate all the work you do for the side by sides. You don't get enough credit for that sometimes. Thanks for the info, especially on glass, the white pixel fly aways drive me nuts, so I'm looking forward to these possible solutions.
