Can I update my GPU emitters once they start?
I think this is aimed more at one of the epic devs, but what I'm trying to do is change the constant acceleration on my emitter on the fly at run time. For example if its set to 0, 0, -980.0 can I then set it to be 0, 0, 500.0 on a button press during runtime?
I'm not sure you can due to the nature of sending stuff off to the GPU and letting it go on with it without having to send hold up things with back and forth communication with the CPU, but I thought it worth asking.

Have you experimented with using an instance parameter and modifying the acceleration with a Blueprint?

Actually I've started work on this now in the way described in the comment. I have another related question but I'll open a new one.
