Niagara Vegetation Growth
Using particles as vegetation emitter to quickly populate an environment with foliage.
Niagara Lightning Ribbons
Experiment using Niagara to create a lightning bolts that dynamically links 2 surfaces.
Niagara Fast 2D Fluid Simulation
Using Niagara Simulation stages I was able to do this fast 2D fluid simulation. It takes 0.5ms on my RTX 3070 with 5 Interactors and I can add as many as I want for a minimal cost.
This is some of the work I did for the game Death Garden at Behaviour Interactive inside of Unreal Engine 4. It includes some Materials for environment and special effects, post processing and blue prints.
