Dynamic Floor

I started playing with a dynamic floor material for a prototype of a game. But I liked the effect so much that I kept working and improving it. Watch the video too see what it's all about.

INFO:

It's easy to add grid influencers (up to 1024) which is the material parameter collection limit.
The material uses a custom HLSL node though because otherwise I wasn't able to loop through the material parameter collection.
The grid makes use of unreal's mesh instancing systems which makes drawing the cubes a lot more performant then every cube being a separate object.
