Hi, I’m kind of new to UE4 and i would like to know how to make a parameter for the projectile which is a mesh or a particle(if the process differs i would love to know how to do each of them)to slow down on hitting a certain static mesh i have created and another parameter for when the bullet should stop after penetrating the same static mesh(not like bullet drop, i want it to stay in the exact spot the projectile had reached after it stopped completely)
feel free to explain it like I’m total noob 
Thank you in advance
