Getting used to bsky, so I guess it's time to write a bit about myself...

Hi! I'm Mr F.

I work on my game, Faded (see pics).

I wrote Bakery, a GPU Lightmapper: assetstore.unity.com/packages/too...

I also wrote a lot of other stuff: ndotl.wordpress.com/cv/

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...

Bakery v1.97 is live on the Asset Store!

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...

Following up on the previous post on GPU utilization and performance, and to provide a practical example, I expanded a bit on a topic discussed in brief: vertex shader exports and their impact on p…

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

Github access - Bakery GPU Lightmapper: 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! 🙂

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?)

Mr F @guycalledfrank.bsky.social · 28d

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 😋
(video from RTPreview for fanciness, but it looks the same when baked)

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

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

Mr F @guycalledfrank.bsky.social · Sep 2

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.
