My custom bullet does not collide, any ideas?

I have experience of UDK but this is my first attempt at using Unreal 4. I used the third person template to begin. I have got my character firing using blueprints but the bullets do not collide with the walls or any of the others meshes in the level and this means the player can simple shoot all the enemies from the start position. Can anyone help?

Here is how the blueprint in my bullet is set up

And here is how the collision is set up in the sphere collision, the bullet mesh does not have any collision at the moment but I did try using some, they did not make any difference.

try changing the collision preset to Projectile.

I could not find a projectile collision pre-set but I have just been through and tried all of the pre-sets available and none of them made a difference.

Your collision sphere probably is colliding, while your actual mesh isn’t. Uncheck “hidden in game” on the collision sphere to see if it’s colliding or not, and if it is, simply drag the mesh onto the sphere to make the sphere the root, which will give the mesh the same properties.
