Paint shader

Hello guys i want to make something like at video. When car hit the ball the color paint the road. How can i make that ? Is it possible to make with shader graph ?

You have to find out a way to store the painted areas and then render it with a shader (for example). It can't just be done with a single shader as you need the data stored, so you need to save it somehow, in a RenderTexture or by some other method that is fast enough for your game.

It is not trivial so I would suggest looking in asset store or googling on topic like "splatoon like paint effect" etc. There are a few threads on this forum too.
