Welcome to this series on procedural landmass generation. In this episode we add mesh colliders to the terrain and get a character walking across it.

$Coding Adventure: Rendering Fluids Weve succeeded in the past to make a bunch of little balls behave like a fluid, but can we now make them look like a fluid too? In this video well explore a few different techniques, and also attempt a simple simulation of foam and spray to liven things up!
