Along with the first tip of closing other programs, add your project to Render Queue - close C4D - open again and start the Render Queue without opening the project. Go out for a coffee while it renders. ☕

Thanks, I learned some new stuff! I never understood what "Russian Roulette" was, and I was always afraid to mess with it. But I just finally figured it out (a bit), and basically it tries to optimize how reflection, refraction, etc passes are handled. I had a very simple scene with a bunch of planes with an alpha channel material to cut them out. I needed a Transparency Depth of 6 for the occasional time when several were overlapping. The renders were going pretty slow until I upped the Russian Roulette setting to 0.1 and that alone sped up my render time by about 5x (without any noticeable difference in quality)!

Boosted my 3090s Performance literally 400%, thank you so much cant believe it!

if you really want to speed up RS in Renderview in System Tab - put memory limit to 60-70% and put GPU memory realise to 60-90 sec also Hardware Raytracing in Globals is slowing down quite much time to first pixel in IPR I'm avoiding this until putting to render farm, also good alternative for complex scenes is In Renderview/View/ IPR Undersampling set to 2-3 for example

CG Shortcuts has my favorite tutorials. Is there any chance we could expect a new settings tutorials based on M Series Macs? A lot of this is no longer applying to what I'm doing since things like oPtix and the Rendering Engine "Prodction" vs "RT" are only available for NVidia?

Apparently Apple built these in part to get a larger share of the 3D modeling and rendering market, maybe it makes sense to throw users a bone? If I never used another Windows machine in my life I would be pretty thrilled lol.

The greatest time-saver tutorial, huge thanks

[roscodottv]

Great tips as always Dave, def agree autosampling is a winner!!

[nadinec]

Thank you for the tips! They helped me to significantly decrease render time

[BoldBreak]

Great video. It is worth exploring the unbiased sampling by turning off automatic sampling when you're getting closer to the final render. This allows for precise control over certain areas of the render.

[DeibydPerez]

This has helped me a lot. Thank you very much for your time and for sharing.

[Vmshipe]

Very helpful! Is there a way to save all these settings for Redshift so you don't have to set them up every time you open C4D?

[olano]

thanks for sharing that in such a great and easy to follow manner

[ryan.massiah]

The RS Material database tip is very useful.

[pushcreativity]

I have always used Irradiance Point Cloud as my secondary engine, and 512 as my bucket size. After watching your video I changed them to Brute and 256 and reduced render time by about 20%. I just tried that on an exterior scene and the render times went up, so Brute force or Point cloud I would suggest are scene dependent.

[mehmetyigit]

and u can use decrease trace depth. espectially if so many reflection or refraction materials in your scene.

[kudjo]

Can you make a video going over how to handle RS displacement and tessellation correctly when using Megascans Quixel assets? It is absolute hell as the default values are never just 0 or 1 in the range mapper, also depends on the scale of the Megascans asset (small boulder vs mile long cliff face). I can literally NEVER get my displacement for Megascans rocks or whatever to look exactly like it does on Megascans site, is always rounded off slightly or looks bloated.

[samnhatvu]

Thank you for such good tips and excellent explanation video!

[frankwerner]

In A Nutshell

1. Close All Apps (especially After Effects)
2. Set Progressive Passes To Something like 32 - 128 (should be your default)

Works every time for me :D

[_FASADO_]

In the render preferences, how come when I disable my CPU to only use my GPU it doesn't let me render, and I even get "licensing errors" codes and the Maxon app pops up ?

[mmd]

Hello, how do I remove watermark "redshift" in render view in c4d 2024? Thanks
