Using Amplify Shader Editor I have created a cool low poly shader for unity's default terrain (SRP). Thought some people might like it, if there's any interest ill chuck it on the asset store. It's flat shaded, uses splat maps, custom highlights and shadows and has an outline effect. If you want to recreate on urp/hdrp its something along these lines: Uses the tangent cross product of DDY/DDX to generate normals Light direction and world normal to lerp between highlight and shadow tone And a Fresnel to get the edge effect.
