First Person Hitboxes Replication issue

Hi everyone,

I’m working on a Multiplayer First Person Shooter and having an issue with the way the hitboxes are driven from a client perspective. I’m using an additive animation to place the weapon a bit better in the first person view and it is (without a surprise) also affecting the “server’s” character hitboxes. So when clients’ are trying to shoot the server’s character they might be missing even if aiming right at its arm or hit shooting a bit higher.
Is there a way I can disable replication of that additive on the clients?

I’m also not sure I’m using the proper workaround for these types of games : I only have one Skeletal Mesh used for both the First and Third Person views.
