Small addition to yesterday's post for correct pixel-grid lighting 💡
Updated the grid stay consistent even with rotations.
Explanation below 👇

We need to create our own TRS matrix, by ignoring the 3x3 scale and rotation part. We use that to go into 'Kind of world-space'.
Scale is still going to be weird. Don't think there's an easy way to separate scale from rotation in the TRS inside shader code.

💡☀️Working on the pixel-art cell shading for #BoneToPix & The Bleak Divine

A short thread on how I got lighting data to work on *art* pixels instead of *screen* pixels 🖥️

👇🧵 #MadeWithUnity #GameDev #PixelArt

Fragment shaders work on screen pixels, not texture pixels. In pixel-art styles 1 pixel in your art is going to be rendered over a bunch of screen pixels

That means you'll have different data for different parts of a texture pixel-> so you won't get the neat per-art-pixel look

The solution is to snap our data to an art pixel-grid.

We're gonna need to align both vertex positions and fragment positions to our pixel grid.

First, the vertex snapping, in the vert shader:
