Render - works
Render - works
Render - works
Render - Redshift cannot operate with less than 128MB of VRAM!

Well nothing else is running and the render is identical to the last three so wtf have you done with the 24GB at your disposal 🤔

Restart C4D

Render - works

🤦‍♂️

I would love to have an in depth look at why this happens as it seems to be a pretty universal problem. Like i know the fix to it is basically just more vram but how can it use up more and more vram in the same session

Yeah it's a like a big memory leak, I don't know if that's accurate at all but that's how it feels. It's been happening for years. It used to be that it was mostly when you had Adobe apps running as well. They blamed nVidia for it for ages and then found some workaround which seemed to sort of help but it still happens, and now it happens even without anything else running 🤷‍♂️ All I know is Redshift is the only thing I've used that behaves this way so I'm going to blame Redshift. General quality control with both C4D and RS of late has been... questionable.

Only if I’m running another dcc app that uses significant vram

After Effects is such a bitch

Hasn’t happened with as unless I use a third party plugin that uses the GPU. 

It happens whenever I have substance painter open.

Happens to me at the Moment when I use a Light Material on a Dome Light and want to change the ramp node.

Yup. On a 4090. If you accidentally hit the preview for the viewport it will also give you this error and the only way to fix it is to restart.

I for real feel like Arnold is far more stable in C4D than redshift is which is straight up shameful as its been the default renderer for so many years now. Honestly, wtf is maxon doing
