Advice needed: EVAC-style plasma procedural background

Unity Engine
1

If any of you have EVAC for iPhone, you will know the menus have as their background a kind of procedural plasma effect… I was wondering if any of you know of any online tutorials about how to achieve that kind of thing in Unity?

I was thinking of doing it with a simple vertex coloured mesh, and changing the vertex colours over time, but I’m pretty sure it wouldn’t look anywhere near as nice as Evac’s effect.

Any advice would be gratefully appreciated!

This looks very simple. Just use a Particle System that moves very little. Large round blobs that mix. It will look exactly like what you want.

That’s the one, yes. Ah, particles, hadn’t thought of that, thanks! But how they mix is beyond me - I’m a complete beginner at shaders, is there one particular shader that will be a good starting point?
