Concentric Hypnotic Circles


I’d like to create a material in UE4 with concentric rings that constantly shrink towards the centre. Just like in this video HERE.

I imagine I would use a sine wave for this maybe but I’m not sure how to begin.

Any ideas on technique for this goal would be much appreciated. Bonus if you know how to achieve the same effect in Niagra.


Here’s one of my material functions. Shouldn’t be too hard to alter it to make solid rings:

Wow! Thanks so much.

Do you think you could share the values of each of those scalar inputs? I’m having a lot of trouble dialling them in.


@TheJamsh , Pretty please?

Also bumping in case anyone else has a method they’d like to share.

@TheJamsh One more bump for those values just in case you missed it.
