the title speaks for itself… however i’m wondering if there’s a clear velocity that UE is basing its add velocity module on.
this is likely to be useful when i wish to use it for various bullet sorts for reasonable shooter video games (though you’ll set the speed up in bullet BPs not in niagara)
anyhow, simply curious. can be good if somebody might clear this up 
Niagara makes use of the identical “1 UE unit = 1 centimeter” conference, so in case you set a linear (1,0,0) velocity and 1 velocity velocity scale in Add Velocity module, it strikes the particle ahead 1 centimeter per second (if there is no such thing as a different velocity module in the identical emitter). If you wish to set “meter per second”, simply multiply the velocity scale by 100.
Like you could have already mentioned, you’ll do the bullet in BP as a substitute of Niagara, as a result of Niagara occasion handler could be fairly taxing. In the event you connect the trailing Niagara impact on the bullet and must seek advice from the bullet’s velocity in Niagara, you need to use the “Engine.Proprietor.Velocity” which is simply the resultant (world house) velocity of the actor.

thanks! cleared all my query about this
