Question by weltraumimport · Dec 16, 2018 at 02:38 PM · unity 5shadersunlit

Make Unity Unlit Shader use normal maps.

Hey everyone, I've been trying to make a toon shader for a project of mine and wrote a Ramp Shader as Unity Unlit Shader. The Ramp is controlled by a fake Light object in the scene, so I wanted to try and add a normal map on top of the Main Texture and Ramp Texture but I have no idea how to approach this as Unity Unlit Shaders are... unlit and therefore are apparently not able to take normal maps? Any advice on that?

That's not how that works. An unlit shader is specifically created without lighting information and a normal/bump map REQUIRES lighting information. There is no way to use a normal map without lighting, if you were to write a shader to accommodate for your custom light, you'd basically just be writing a lit shader. So a better question. Why do you think you need an unlit shader with a normal map?
