Can still see player while playing animation in first person

I have a running script that plays an animation but when the player goes into first person they can still see their character and I would like to know how to fix it.

If you have custom parts, that might be causing this behavior. I don’t know of anything else that can be causing this.

It’s very likely what @cnr123451 said or it could be the way the animation is leaning forwards.

Yeah I had a script to insert a viewmodel that was messing it up
