I want a 2d terrain in Unity that can be edited in Scene view. I have come across a github repository which nearly serves my requirements, but I am not sure what exactly I can do to make it have another texture on the top layer to create an illusion of the platform.
I have searched extensively and didn't find any methods to do this. I am not looking for Paid solutions like Ferr2D, Zippy Terrain 2D Terrain Creator etc.
I want the the terrain to be able to have curves and splines etc.
