Any idea on how to make an ability fire out of two meshpoints simutaneously?

at the sametime? If you set the ability to that meshpoint such as Ability-0 it should technically work

I have tried setting one, basically it charges up on one point and fires out of the other.

I'll clarify. My ability has a charge-up buff effect, a beam-firing effect, and an impact-damage effect. What I've been trying so far is having the charge-up effect and the beam-firing effect to fire out of two meshpoints at the same time.

Ooh ok that clarifies a bit, So you have to ensure the buff abilities are also on the same ability point because if not itll hop on to the other, if that doesnt work then i would recomend starting to test with one meshpoint first with the ability and if it does work the way you want then copy and paste to the other

So should I have two abilities firing out of two meshpoints? Because I want a firing effect where both guns fire simutaneously.

That might be an option but to be honest you might have better luck on the Discord chat sorry couldnt much more help
