So im trying to make bullet holes when the bullet hits something so how to do this?
Bullet holes aren’t really something that you can realistically do, but you can spawn a bullet hole decal which is what is used in most shooter games. Read this documentation: 1.1 - Basic Decal | Unreal Engine Documentation
And this is one way how you spawn the decal when the projectile hits something (get the rotation from the hit normal)
Sorry for the late response and thanks for the info
Yes you wanna get the projectile hit event and get its hit location and hit normal for location + rotation to spawn a decal at. Make sure its got a transparent background and the material editor is setup properly with your bullet hole decal texture.
