Population Tool Creator

The Population Tool is a locator node which provides an easy way to place particles in the scene. Each particle will be given a direction and an Entity Type. It also provides some parameters to specify the population (Entity radius, Entity Type weights in the population, distance, noise…).

 

The Population Tool locator can be mapped with a Terrain Locator. In this case, particles Y position will be defined according to this terrain.
