"SteamVR stereo layers are using the wrong coordinate system conversion and are being improperly rotated. All other conversions in the SteamVR module are using the correct one, just this particular section isn't."


See PR

Steps to Reproduce
  1. Create a VR Template Project
  2. Add a StereoLayer component to BP_MotionController
  3. Attach StereoLayer to MotionController or HandMesh
  4. Move StereoLayer forward in the X axis (~100 units)
  5. Set to any texture, but texture compression must be set to UserInterFace2D (RGBA) or it will not be visible
  6. Set Stereo Layer Type to World Locked

Play in VR Preview with Vive - Result: Roll rotation is reversed
