How to make object invisible for secondary camera? I was wondering if you could make an object invisible to one camera, but still visible to another in BGE
If you are doing render to texture you can simply by doing:

obj.visible = True
camera_tex.refresh(True)
obj.visible = False
camera2_tex.refresh(False)


I am not sure if you can do it if you are using viewports.
How are you setting up your two cameras?
