Unable to spawn emitter with blueprint
Hello esteemed Unreal brain trust,
I have spent the better part of the last 4 hours scouring the web for the answer to this problem, but I have been totally unable to use BP to spawn a particle emitter.
I am able to place my emitters in the level from the CB, and they work normally. I created a door animation BP, with the intent being that the door should open once and then "short out" and no longer work. I wanted this to be accompanied by a shower of sparks.
I've attempted the process with both the "Spawn Emitter Attached" function and the "Spawn Emitter at Location" function. I'm using an empty that I placed in the Components window to determine the location I want the emitter to spawn at. I've also tried leaving the location disconnected and using a real time wire view to see if the emitter is spawning somewhere else in the level. It doesn't appear to be.
Please help! :)

Spawn Emitter works fine for me in 4.5.1. The only known issue with Emitters in Blueprints is that collision modules in the emitter won't work properly. So if you are spawning the emitter at a location right above the floor, for example, the particles will fall straight down and you might not see it.
Have you tried this with any of the Starter Content emitters with the same result?
A good way to check to see if the emitter is being spawned is to use the Is Valid node after the Spawn Emitter node. It would look like this:
If it is in fact being spawned, then it's just a matter of figuring out where and why. I would start with the variables you're feeding into the Location and Attach to Component (using Print Strings for their locations) and using an emitter with a longer life-span (or unchecking Auto Destroy).
If it is not being spawned, please let me know and we'll look into it further. Thanks!
