[solved] make mesh, sprite invisible for just one camera


Recommended Posts

If I get it right its not possible to show one komplex scene in two cameras completely and just one or few meshes in the scene are invisible for one of two cameras.
The only way I see is to add more cameras which show/overlay the 'secret' meshes. Right?

It is possible. This is the goal of the layerMask: you can have objects visible only for one camera and some visible for both.

For instance let's say that camera1.layerMask == 1 and camera2.LayerMask == 2

  • a mesh with a layerMask == 1 will only be on camera1
  • a mesh with a layerMask == 2 will only be on camera2
  • a mesh with a layerMask == 3 will be on both

The layerMask is used to do a bitwise comparison

So I need 4 cameras for a local coop game with two players who want to see the whole world and each his crosshair/gun sight.

Example:

  • player01:
    • camera1 with layerMask == 3  // world
    • camera2 with layerMask == 1 // crosshair for player01
  • player02:
    • camera3 with layerMask == 3 // world
    • camera4 with layerMask == 2 // crosshair for player02

I am right?

How strongly a new camera affects the performance? Does this kill performance on mass for a 4 player coop game?
