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...

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! 🙂

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 😋

The terrain above is based on an erosion noise implemented by clayjohn and Fewes in this Shadertoy:

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

Using Bakery realtime preview by @guycalledfrank.bsky.social to check area lights... to be baked into volumes for Light Volumes by @sim.red ... to THEN be used to provide the walls, fog and avatars in #VRChat with realtime light information from the screen.

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

Questionable UI, but Decalery now allows you to project receiver's UV1 (for the normal map) to the decal, while moving original decal's UV1 to UV3 (for color/gloss/etc maps).
Basically cheap forward-rendered normal-mapped decals.

Basic trigonometric IK, but it's satisfying when it finally works.
Previously I wrote an overly complicated position-based solver, but it was buggy and wasn't worth it 🥲

Added de-ringing option to L2 light probes. Unlike Unity's "remove ringing" checkbox, this one is actually a slider you can tweak to remove less/more. At max value it gets almost close to L1, but seems to fix ringing/negative values completely.
Oh, I also made L2 work for APV.

So previously Bakery had 2 light probe baking modes: L1 and Legacy (=L2 but via convolving in-engine rendered cubemaps). L1 was 1st-class citizen, since it also works for dense 3D texture volumes (no way anyone's reading 9 textures).
Well, now L2 is finally a "native" mode too.
