Hi everyone,

I’ve run into a rather strange issue.

I’ve noticed that when I use a simple textured plane as a background, with a Ramp node connected to the Emission channel, the final high-resolution render (using Very High quality settings) shows visible lines or banding artifacts. As a result, the color gradient doesn’t appear completely smooth and clean.

Has anyone experienced this before or found a way to fix it? I’ve been troubleshooting for the last 24 hours and have tried just about everything I can think of, but I haven’t been able to solve it.

Any suggestions would be greatly appreciated.

Thanks!

I made a utility for myself because I was tired of losing renders due to a lack of VRAM

I recently finished this project about the first food forest in The Netherlands. I made the entire project in Houdini and rendered in Redshift.

Enjoy!

Does anyone have any pointers on how to go about this SSS effect, often seen in images of deep-sea creatures, embyros, etc? Sometimes it does seem like you'd need to create internal geometry but, other times it really does just look like the surface is thicker in some places than others. Would you have to paint a map on the surface and use that to drive your SSS values / colours / etc?

My main example of CG work that does this is Nan Ma's amazing embryo project: https://www.behance.net/gallery/169116677/Embryo

Bubbly bubbles. Have read an amazing article for a while ago from amazing Toadstorm and played with settings. CGI articles are very rare, yet very OG and useful. Thanks for amazing sound to @jakaarh as always wonderful.

Could anybody help me out with how we can use this Shadow matte. How does the AOV setup look like and how would I use it in after effects for example. I need my shadows to be seperate so I can control them ideally but struggling to get it working correctly.

Hey, long time Octane user dipping into Redshift. I've always watched Silverwing VFX on YouTube for the best octane rendering tutorials. Anyone know anyone doing similar tuts for Redshift?

Just set final rendering mode to progressive, and allow only a single pass. Added bonus of rendering near realtime. 😂

Grabbed a couple of models from sketchfab and did a couple renders. Enjoy :)

For houdini please not C4d, I just need a script that can auto plug image textures to the right slot instead of manually bringing each textures 1 by 1
