I am trying to carve out some wear lines on a bullet, from where the barrel of a gun would cut into the metal. I am using a boolean modifier on the bullet, set to difference.
It cuts into the object ok, with the striations / wear lines in the right place, but the bullet is now hollow inside. Is there a better method to achieve something like this?
EDIT: Hollow effect appears when boolean object is close to flat end of bullet.
