How I did the caustic lighting in Unreal Engine 4 with light function.

Hey, finally ! A new tutorial video, I hope it's useful for you.
Basically, I'm showing you how I used the light function inside of unreal to create these caustic lighting effects. It's really easy, but the trick is in the material function and playing around with the panner function and the scale.
It could be greatly enhanced by playing a caustic animation instead of using a still but I haven't looked into that yet. I'm curious if any of you guys have ? Cheers, Fabrice.
