Stereo 3D

Full Changelog: v4.2.0...v4.3.0

Update

• Now supports stereoscopic rendering for overlays. Set the flag sideBySide3D for an overlay payload and it will split the texture in two and show one part for each eye in VR.
• Added flag to show/hide the laser pointer intersect indicator dot with input.mousePointer.
• Now automatically supports multiple pointers when input is enabled.
