I’m curious in Unreal 4 how to perform the visual effect as if the space is collapsed towards the center as in the following figure. I’d like this effect to take place at a certain location with a certain radius.
What I’ve achieved is pretty far from it: apply post-processing material where the uv of any point in the circle is replaced by a point on the circle, shown in the following figure, which looks ugly.
Any suggestion is much appreciated !
