Please download and follow along with the examples and experiment - always the best way to learn!
Today we're going to be using the things we've already learned about Math and Vectors and applying them to a very powerful input node in the Unreal Material Editor - World Position Offset.
Hopefully that gives you a few ideas for how we can control our Vertex offsets and animations and inspires you in your effects work - recently Unreal has started developing tools for baking Vertex animation (such as fluid or cloth simulations) into a Texture and reading that back like a flipbook, which is incredibly exciting for the future of Vertex animation.
