I have a two camera setup for my VR scene. This allows me to have two 360 mapped spheres, one for the left and right eye, so that I have stereoscopic 360. This works really great, but now I need to add hotspots and also include a way to interact with them.
My question is this, how can I add a reticle to my camera now that I have split the camera up into left and right? I tried adding a sphere to the Left eye camera, and put it on the UI layer so it would not be culled by either of the cameras. This works, in so far that I can ‘see’ the sphere in both eyes as I move my head around. But I get a huge shift in the position of the sphere between eyes. The effect is that I get horrible double vision when looking at the sphere.
I think I may have to add the reticle object outside of the camera and then move its position to the camera on every frame.
Any other ideas?
