Syntax
TOptional < FGuid > ExclusiveEmitterHandle
Remarks
An optional emitter handle guid you can register. This will skip parameter map building of all emitters that don't match this one, if set. Reason for this is to be able to build parameter map history for a system, while excluding certain emitters. Useful for emitter context UI that should retrieve system parameters & emitter parameters, but only emitter parameters of the given emitter.
