Cycles Development Updates

[Voidium]

seems like non of us saw this coming, but I’m happy for once to have guessed wrong

[lsscpp]

For this and for the future, we definitely need some sort of CyclesLeaks® site!

Thanks you, I got the branch to build but got errors in Cuda and Optix kernels.
Nice WE for testing.

Cheers, mib

Daaaaaamn… hype was worth it

yw, I tried building it too, but got infinitely stuck on hpdf_destination.h
Prolly just a one time thing.

Hi, I make a new thread about CyclesX for testing.

Cycles-X

Hi, today the Blender Foundation published the next step for Cycles, work name Cycles-X with a new architecture, kicks tile rendering and better performance. More information: Blendernation overview: Test builds of Blender 3.0.0 cycles-x branch are: https://builder.blender.org/download/branches/ Technical presentation docs of CyclesX: https://docs.google.com/presentation/d/13Zo2gafKyIFEyZCBucEfFHrrrwz9RBQoIImC6nBCgEE/edit#slide=id.p My first test render are very fast but view port render …

I guess there are other Cycles development in the next month, at least I hope so.

Cheers, mib

cycles is 10 years old
That means I’ve been using blender for 10 years. Wow what a journey.

Guys, I hope you don’t mind that I’ve moved the recent Cycles-X related posts to the new dedicated thread about that. I think Cycles-X deserves its own discussion. Come join us there:

Hi, Cycles development goes further:

https://developer.blender.org/D11088

I will check the patch on top of CyclesX, if I can get it to work.

Cheers, mib
EDIT: Cant get anything meaningful out of it.

Does anyone have a performance regression when using Optix vs CUDA? I was experimenting with 2.93, (we are still on 2.79), testing out both Optix and CUDA, and Optix was around 30-40% slower then CUDA?

I thought reading around that CUDA was supposed to be slower than Optix. Maybe its the scenes we do.

[Voidium]

Optix is slower then Cuda if you are using a 10xx graphics card or lower, it needs those RTX GPUs to take advantage of their RT cores / Tensor cores.

Some pretty impressive test with the experimental texture caching branch.

Tiled EXR / texture caching support?

On a brand new windows laptop (meaning it’s sat on a shelf for 2 years with no driver updates) OIDN produces a blank image in 2.92, 2.93, 3.0, and cycles-x. I’ve run windows update and nvidia driver update and it’s still happening.

[silex (Jakub Jaszewski)]

Better detail preservation sound great. NLM denoiser might eventually be obsolete.

On a sidenote - any news about new rendering developer? Seems like Cycles-X stole the spotlight so far.

[Ace_Dragon]

I believe the new render engineer starts in June, so we are a few weeks out from his first commits.

[captainkirk]

I’d love to see that on an animation and see how stable it is.

[brothermechanic]

Wow
Please, write how to do that? What is pre-filtering?
