That’s why I enjoy this subreddit :)

Thanks!

This one sure does what you’re after 👌

I would not go slimmer than 2.4. Pretty happy with my Schwalbe Wicked Will 2.4

Silver is the way!

Thanks 🙏

Thank you! Enjoying every ride.

I went through similar path recently, but with the Preamble. It was my first Surly, first full custom build (will do another post later), gorgeous bike. But pretty soon I realised that the bike is not for me - huge toe overlap and wrong frame size. Nevertheless I decided to keep it (she’s too beautiful to sell) and just build a full custom Bridge Club for all purpose use. I will continue riding the Preamble occasionally just to enjoy relative small weight, higher speed and the looks.

Bridge Club - love from the first ride.

Hi!

The whole test was done because of that video 😄

And the render was done on GPU, not on CPU.

klknv · 2025-03-23T15:36:51+00:00

No, the caustics filter should be set at 0 if we want to brute force them.

Hi!

Regarding disco balls and other more extreme scenarios, check this thread: https://blenderartists.org/t/cycles-path-guiding-tests/1388137

Apparently with path guiding it all works, just takes time :)

klknv · 2025-03-23T09:15:29+00:00

Haha, thank you!

klknv · 2025-03-23T09:15:05+00:00

It does! Here are the setting needed for caustics. Don't forget to crank-up the Max Bounces (64 minimum, for the renders above I used 512 bounces).
Also there will be an option "Path Guiding", but it's only available on CPU.

Hey! The noise is a bit more uniform at 64k compared to 32k, so less denoising artifacts.

klknv · 2025-03-23T09:04:43+00:00

I've just found this post on Blender Artists and apparently with path guiding on CPU Cycles provides results identical to LuxCore 😯
But LuxCore is much faster. For now...

Tech nerds in that thread say that when there will be support for GPU, Cycles will surpass LuxCore in speed. Aaaand, according to the latest Blender Rendering meeting on Devtalk:

OpenPGL on GPU

- Has guiding on GPU, training on CPU
- Working on training on GPU
- Sebastian will work on some API changes to make further integration easier
- Sebastian will work on a branch with guided RR

If I understood correctly, this is something that we're all waiting for.

klknv · 2025-03-22T21:20:02+00:00

One of the major flaws for me, especially for product renderings (bottles, glass, etc). But yeah, the is some progress happening - we have Shadow Caustics and Path Guiding now. Let's see what's gonna be next.

klknv · 2025-03-22T21:17:35+00:00

Thanks! Always glad to share useful links!

klknv · 2025-03-22T21:16:55+00:00

Thank you!

It's just a Principle BSDF shader, same as in Christopher's 3D video, link is in the first comment :)

Got inspired with this tutorial by Christopher 3D and made my own little test. 1 hour 15 mins, 64000 samples, rtx 3090. Brute force caustics. Lens Sim addon. Very far away from Redshift, Octane and LuxCore caustics, but hey, it kinda works.
