Sets an Effect ShareSet at the specified Bus and Effect slot index.
Note: Replacing effects is preferably done through a Set Effect Event Action.
The Bus can either be an Audio Bus or an Auxiliary Bus. This adds a reference on the audio node to an existing ShareSet.
Note: This function has unspecified behavior when adding an Effect to a currently playing Bus which does not have any effects, or removing the last Effect on a currently playing bus.
Note: Make sure the new effect shareset is included in a soundbank, and that sound bank is loaded. Otherwise you will see errors in the Capture Log.
Note: This function will replace existing Effects on the node. If the target node is not at the top of the hierarchy and is in the Actor-Mixer Hierarchy, the option "Override Parent" in the Effect section in Wwise must be enabled for this node, otherwise the parent's Effect will still be the one in use and the call to SetBusEffect will have no impact.
