normal mapping tilemaps

Hi forum, sorry if this is the wrong spot.

I'm looking to add normal/bump maps to my tiles in Unity 2018.3. I have a custom surface shader that makes use of a bump map, and its working fairly well on its own. But when I set the TilemapRenderer material to my custom surface shaded material, I can't find a way to control the normal texture per tile. It seems like this might just not be supported. I did find this, but it seems pretty limited. https://github.com/Unity-Technologi...pping/Material/Shader/NormalMappedTile.shader

I'd really like each tile image to have its own normal map.
As anyone done this? Is it not possible yet?

My surface shader is pretty much a toon-shader plus a hatching shader. I'm going for a game with a cartoony-sketched vibe. It looks like this, when applied to some sample test art.

(for anyone curious, this shader is pretty much 100% stolen for this paper, http://hhoppe.com/hatching.pdf)

Any help would be greatly appreciated.
Thanks, world.

Thanks for the quick response I hadn't thought of trying to atlas the texture. So that'd mean that all my tiles share the same texture, but differ in UV coordinates. I will research that when I get home tonight. I'm hoping its as simple as a code tweak... or do you think its more involved?

 

I copy pasted shader and material from github, it doesnt work. Sprite atlas of normals is the same as sprite atlas of tiles. Why?
