Hey #IndieDevHour! 👋

Previous thread with the start of the tutorial for per-texel cell lighting:
The main trick for this one is doing a 1:1 mapping of texels in our main texture to texels in the dithering lookup
Then bring it into the [-1,1] range and scale it.
The sampled offset is used in the CellLookup
Make sure your dithering lookup is set to wrapped for this to work

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

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:
