Located under the Container plug-ins tab, RFxColliderSrc is used in conjunction with RFxColliderTgt to create a collision and collision detection system. For example the source could be a notional wall or floor, whereas the target would be the particles themselves. The particle target can work with a number of sources.
Note: When RFxColliderSrc is added to a container, the RFxCollisionManager plug-in is automatically added at the scene level. This plug-in is used internally and not configurable.
Note: This plug-in is located in: Built Ins -> Container plug-ins -> RealFX
