I was tasked with creating a demo for something involving VR. They want people to use the VR headset, but they also want to visualize some of the calculations that go on behind the scene to the audience.
To that end, I was asked to have the computer screen show something different to what the VR is showing.
The difference would be the addition of objects from a layer that isn't included in the
OVRCameraRig's left and right cameras' culling mask.
I've tried messing a bit with the code in the
OVRCameraRig script to make sure all 3 cameras (left, right, and center) are enabled, but that didn't work (and I'm hoping there's a simpler solution than debugging that script to try and make that work)
I've also tried adding a camera as a child of
LeftEyeAnchor with its culling mask set only to the additional layer I want to overlay, its target set to
Left eye, and
Clear Flags set to
Depth only, but that led to the right eye getting nothing and the left eye getting the object I don't want to be seen on the VR goggles.
Is there a way for me to either get the overlay to only show up on the screen or create another window that will show everything without a 3rd camera that repeats everything already done with the other cameras? (That is, I worry that adding a 3rd camera with its culling mask set to "everything" and having that displayed on another screen would drop the FPS)
