Aimer Visibile in Only One Display Region

I’m making a game with two viewpoints (a split-screen multiplayer for a shooter). I already have aimers in my game. However, I want the aimer for player 1 to only be visible in player 1’s section of the screen (player 2’s viewpoint will not render player 1’s aimer).
Does anyone know how to do this?

(If it’s important, I use display regions to make the split screen.)

Set a different bitmask on each camera, then you can hide objects in each view independently.

mask1 = BitMask32.bit(1)
mask2 = BitMask32.bit(2)

Awesome. Thanks.
