Unity shader stories - Creating a two colour gradient
In this tutorial we will show you how to create a two-color gradient in shader code, without requiring textures. This technique is particularly useful for creating more visually engaging backgrounds for your 2D games than simple solid colors.
We run through how you create the gradient effect by using the UV coordinates to get our object mapping and instead of outputting a texture we output the colours at each vertex and let them be automatically interpolated for us.
At the end I include a bonus little script to show you how you could animate these from within your C# project to create a basic day-night cycle.
