Cubit Studios Ballistics VFX pack with example blueprints

well I got it to work, but I had some issues and have some questions.

so after I did the steps above I decided to remove the balisticsvfx folder and then migrate it again. This made everything work.

but I cant get the damage to apply to any of my AI actors. This was the simple code I had in my original projectile base which worked. I added a simple code I found on youtube and my projectile was able to kill all AI and cause blood to spatter when I hit some AI.

also just what has this pack done to my project? After I opened it the first time I see

BUILDING MESS DISTANCE FIELDS
COMPILING SHADERS

why does it have to compile the whole game all over again when using balisticVFX? Did I do a major change of my baseline game? I have bought other plugins and blueprints in the past but never on the scope of this where it had to do the entire shaders thing again

So when I add that code to the rifleprojectile I dont get the effects anymore, the only way that it can apply damage to the AI is like this

it works but for some reason it takes more hits from the bullets to kill

and also, the code I had for my blood effects wont work even if I change the cast

it might just be that I am a beginner and am still learning, but I just dont understand what to do to make the balistic VFX projectile to be able to do everything my old projectile could
