I know! I know! I'm a day late! Cut me some slack, or yell at me for being a day late on Discord, that's fine too!
Anyways, this months patreon reward is a voxelization shader.
The way this shader works is by picking 3 points within each triangle on the model and then generate a cube there, and snaps the cubes to a grid in the world. (Think Minecraft)
Because of the way it works, I recommend that you adjust the Grid Size and the Voxel Size together, otherwise you'll end up with intersecting voxels that look bad. (this is of course assuming you change from the default size, which is fine.)
Here's the shader, enjoy, and don't make the voxel size too large! (Overdraw hurts frames)
