From there, you can toggle the visibility of the guide cells on each major axis.Īdds a set of fields for the user to set in the Override Parameters when you click the simulation in the Level Editor.
From there, you can toggle the visibility of the red box around the simulation.Īdds a toggle to the Override Parameters when you click the simulation in the Level Editor. For ease of organization, the summary has been broken down into the following sections:Īdds a toggle to the Override Parameters when you click the simulation in the Level Editor. It includes advanced texture coordinates and is designed for cinematic use.Īll the parameters you want to adjust to change the look and behavior of your simulation will be available in the Emitter Summary. This is an alternative controls emitter that uses a slower, deterministic form for the particle source algorithm.
Density, temperature, and velocity are injected into the simulation from a second emitter. This emitter adds particle source support. These controls are exposed in the Emitter Summary. This emitter adds a centralized controller, debug slice functionality, and better render support. The purpose of each emitter is the following: You will see a variety of different 3D Gas examples to choose from. To learn more about enabling the plugin and creating your first project, see the Niagara Fluids Quick Start. This way, the fluids templates are already set up with the proper inheritance and it will add all the emitters you need to the system.
In the wizard, select the option New system from a template or behavior example. To create a new Niagara Fluids simulation, right-click in the Content Drawer and select Niagara System. This reference guide gives an overview of the Grid 3D Gas Fire template as an example of the design principles. If needed, the results can also be baked into a flipbook and applied to textures for increased performance in real-time use. As such, 3D simulations are best for hero effects or cinematics. 3D simulations have a more realistic look, but a tradeoff in higher memory and GPU cost. There are several different types of templates available:ĢD simulations are more efficient and better suited for games and real-time use. Niagara Fluids is a plugin that provides you with templates to easily add real-time simulations to your projects. Create a Niagara Fluids Simulation from a Template
