I am currently making a mobile game. In it, I have to spawn meshes dynamically. I made most parts of the game in unlit mode cause it would give a better performance. But the problem is in unlit mode, the meshes I spawn dynamically appear to go inside each other. I.e. they appear like they don’t have a boundary.
So I added a distance based shading to add a little more detail to it. They now look like this. I wont be using a single colour but textures later.

anything else can you suggest to add in it to give it more individuality so that its vertices and sides are little more prominent.
