Particle Systems in Godot - Part 2: 3D Particle Systems
Hello Godotneers! In this second part of our particle systems video series we are going to explore 3D particle systems. We're going to learn the basics of how particle systems work in 3D and how we can build effects like fire and rain. We'll have a look at particle attractors, how to make particles collide with the environment and how to use sub-emitters to create more complex effects like rain splashes. There is also a project for you to follow along, so fire up Godot and have some fun exploring particle systems in 3D!
