I want to create a shader that will make spheres/circles look like a blob when colliding.

I don't understand shadergraph at all, but I tried to follow intersection shader tutorials.

The problem is that no one does intersection with another object with the same shader.
Also I want the spheres to be transparent.

I tried calculating vertices to achieve the same effect, but it's a total overkill. I know it should be possible with a shader.

How can I achieve this effect?
