As the particles pass through the volume, the vectors at each location can influence their velocity. Vector Fields are 3-dimensional volumes of vectors created from fluid simulation data, which is then used to drive the motion of GPU particles. This motion is achieved using a Local Vector Field, a feature available to GPU Sprite particles. The effect also has a series of spark particles that come off of the flames and move with convincing turbulent motion. In the above image, you can see the radii of the particle lights, visible when the Preview Light Radius option is checked within Cascade. However, it should be noted that these lights do not currently affect Lit Translucent Materials, which is why the fires used in the level also have a standard Light Actor nearby. The user has control over the brightness and color of the light over the life of the particle, as well as the light's radius. This module spawns dynamic lights at particle locations. The lights are created by way of the Light module within the Particle System. This Particle System simulates a realistic flame that illuminates the surrounding environment.

The following Particle Systems are the fire effects that were created for this example.
