Nice!
How are the blobs applied though? Are they computed inside the receiver's pixel shader? In a loop? Or multipass with blend? Or deferred? Or...

Totally normal skinning

RTPreview was also updated for compatibility:

Better performance, colored transparencies, better light probes, presets, rotatable volumes and lots of other things.

Continuing on the topic of GPU utilisation and performance, as a practical example, I looked a bit deeper into the impact of vertex shader exports on the cost of a drawcall and wrote another blog post with some observations interplayoflight.wordpress.com/2025/09/21/t...

Github access is here if you have the Store one: geom.io/bakery/wiki/...

So, I’m preparing the new Asset Store version (v1.97) for Bakery. Current changelog is here: docs.google.com/document/d/1...

If you can test the latest github version (which is basically what’s gonna land on the store), just to make sure nothing suddenly broke, that would help a lot! 🙂

Video Game Blurs (and how the best one works) How to build realtime blurs on the GPU and how the best blur algorithm works - "Dual Kawase"

Another stunner.

Additional important note: Light Filter meshes still receive diffuse lighting as any other lightmapped objects. Not visible on my video because I'm using a simple multiply-blend shader, but you can sample lightmaps on them (make a dusty stained glass?)

Important notes:
- It tints all direct/indirect rays, but doesn't scatter them. For that try Bakery's SSS feature instead.
- Works with all directional modes, light types, GI, probes, volumes.
- In Shadowmask mode, as masks are assumed grayscale, only R channel is used

So it works now!
If you have Bakery, can you try getting the latest github patch and using it?
Add "Bakery Light Filter" component to an object to make it act like stained glass 😋

Oh boy, got the textures hooked up

Hacking around some translucent colored shadows for Bakery & RTPreview...

Slides from my SIGGRAPH 2025 and CEDEC 2025 talks “Fast as Hell: idTech 8 Global Illumination”, are now publicly available through the Advances in Real-Time Rendering in Games course. Lecture recordings will be available soon on the course's YouTube channel.

Yeah... mostly to prevent any floating issues when re-transforming vertices.

A validation script should probably check for renderer.bounds.center?

Hi, thanks! :)
All your shaders need to do is here: geom.io/bakery/wiki/...

... I didn't mention ZWrite Off, as it's "obvious", but yeah... good point - will add it to the docs now.

It's really impressive, more people doing terrain generation should know about it!

Did you know that GetWindowRect returns -32000 for a minimized window position?
And it's not mentioned in msdn docs.
Well, now you know.
