How to set the visibility of two guns(2 child actors)?

I tried setting meshes in themselves’ blueprints to “Only Owner See”. “Owner No See”, and tried add a macro that set parent’s owner as self’s owner. However, these actions didn’t work.

Hey there @BaituLime! Welcome to the community! If this is a singleplayer game, then you could just use the set visibility node:

However if this is multiplayer, Only owner sees is how to make it visible only to this viewport, but doesn’t hide it from your current viewport if you need it to be hidden.

This is multiplayer. Only owner see and Owner No See is invalid, so I asked this question.
