I want to create a particle system that spawns a single particle that scales from zero size to a constant size over the first two seconds, then holds that size indefinitely. Unfortunately, if I want to create a particle with infinite lifetime, I have to set lifetime to 0. This means I can’t use size…

Sadly by time has been removed when bringing cascade from UDK over to UE4. So all you can do is hope that they bring it back once niagara becomes available. What you can do however, is duplicate your particle, and give it a delay of two seconds. so particle 1: lifetime of two seconds, grows to X …
