It seems my 2024 Everything Procedural Conference talk about Layer-Based Procedural Generation is no longer marked as "for kids" which means functionality is now enabled for e.g. commenting or saving to "Watch later".

So, I made a hair shader that doesn't require any specially made meshes or textures.
Initially I made this work by sampling many normal directions rotated around the hair strand direction, but I eventually got an approximation working that doesn't rely on multi-sampling.

I finally found the time and energy to make a new blog and write a couple of posts. This time I wrote about PBR content and game development principles. Both posts are quite different so hopefully people find something interesting on either one of them.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.
The effect presumably comes from the absence of S-cones in the fovea.
