    Hi, I've made various shaders, have a reasonable understanding, but can't get Unlit working inside
    SubShader{
    #pragma surface surf Lambert
    Gives the standard lighting..... which works ok

    I've tried replacing the 'Lambert' part with....
    "nothing at all" -> magenta error render
    "Unlit" -> Gets ERROR -> #pragma surface needs function name and lighting model:

    I tried adding "Lighting Off" underneath SubShader{ ....but its still lit.

    UNity describes models here.. but doesn't say how to do Unlit / flat color
    https://docs.unity3d.com/Manual/SL-SurfaceShaderLighting.html

    How do you turn off the lighting please ?

    Surface shaders (shaders using #pragma surface) are explicitly for lit shaders. If you want an unlit shader use a vertex fragment shader, which is what's created if you right click in the project window and select Create > Shader > Unlit Shader.

    Just wanted to add more info to bgolus answer.
    So as u already have understanding about vertex/fragment shaders, its worth to mention that surface shader in unity is just a parametric wrapper of fragment and vertex shader. So you can even investigate the actual fragment and vertex functions in surface shader by selecting shader and click "show generated code".
