Hello,
I need some help implementing refraction into my VFXs in UE4.
Been beating my head against this one for a while, since I’ve always attempted to add some amount of refraction to my other VFX but I never got it working properly and in this case, a black hole, it’s pretty much a requirement.
Case in point: I want to make a refraction “swirl” for this black hole VFX which is an ambient VFX i’ve been working on for my game.

Reference would be the very soft refraction which occurs on league’s black holes:
How would I got about creating a very soft refraction like the examples above?
Is there a cheap way to fake refraction?
Or is there some other kind of trickery going on?
Thank you in advance!
