What it is
Sebastian Lague's short Coding Adventure video explores ray marching with signed distance functions in Unity, rendering smoothly blended and fractal-like shapes. It is a visual walkthrough with linked project files and learning resources.

Shaders can definitely do this. It shouldn't even be hard. Sebastian Lague has made a video about this (among other things) that you can find here: [this video] However, I don't know how this places with colliders. I suspect you're going to have to modify that separately; but it shouldn't prove too hard.

Hi i seen this video by Sebastian Lague on ray marching. Link: [this video] At 3:19 mins. [LINK] I want this merging effect but for 2D sprites. Please can someone instruct me on how it can be made or the steps to make it.

You can achieve that effect by using ray marching and signed distance fields. Not sure whether that would be a worthwhile cost for your use case... [this video]
