Yeah, this is from a video tutorial in “ParticleIllusion Fusion Volume 1,” my Creative Cow Master Series DVD which you can get here:
https://www.creativecowtraining.net/
I did use a mix of pIllusion and AE – but in this case it wasn’t displacement maps (or not exactly) – it was the effect in AE called Caustics (Effect > Simulation > Caustics) which is a more complex effect that uses the same priciples of displacement mapping.
You can see an in-depth, 3-part tutorial explaining displacment mapping by clicking on my head, which brings you to a page with a bunch of my tutorials.
