When in Foliage Painting mode, the left trigger press causes the right controller to paint foliage instead of the left controller. This bug does not affect Landscaping or Mesh Painting.
This is a regression from 4.13.2.
Have a copy of QAGame
Connect a VR headset to your machine (Vive and Oculus work for this).
Expected Result: The left controller will paint when the left trigger is pressed.
Actual Result: The right controller paints when the left trigger is pressed.
