RenderTexture MiniMap Not Rendering Terrain

I’m using a camera above my character with RenderTexture (as per Unity3D docs example of a use of RenderTexture). It works great, except that my terrain is not rendering? Culling is set to Everything and that works with all other layers, but not terrain.

How can I get it to render the terrain correctly?

Found my own answer here, apparently you need to be careful of the Shader you use for the camera (this should be mentioned in Unity3D docs and is not).

The above link led me to an answer, follow the Unlit/Texture trail …
