Fire Simulation in Geometry Nodes Made Easy with Blender

Описание

Today, We are creating a fully procedural Fire simulation using Blender 3.5 Simulation Nodes. Starting from a few points, we add some velocity to move them up. After that, we add some curl noise to give it some noise, and then after a few calculations, we create an age attribute to drive literally everything in the simulation.
So, Enjoy!
