Hey catfisherman,
You can see options Owner No See and Only Owner see in Character Blueprint. Go to Defaults and scroll down to bottom of Rendering section. Click little arrow to expand section, then scroll down until you see options for each of two meshes. By default, full character mesh will have Owner No See enabled, and arms/weapon mesh will have Only Owner See enabled. You want to make sure you don’t have Only Owner see enabled on full character mesh. You can see an example of this in action in ShooterGame in PlayerPawn Blueprint.
Hope that helps!
