I'm currently working on a project much like Swat 4 and Rainbow Six 3. I'd like the aiming system to be a challenge in itself so the hope is for no reticle. The issue I have is that the sights are too close to the cameras so you can only see the red dot in one eye. If I change the IPD to zero I can now see it but pulling the eyes closer together makes everything huge. Anyone trying this or if you have some insight into this should chime in.
