Just to confirm; there is no mapping options for the thumb rest sensor on the Touch controllers?

Beginning to work on a project that uses hand-presences and wanted to take advantage of the Touch controllers as much as possible.

Just to confirm the flat capacitive sensor on both controllers has no mapping implementation in Unreal. Was hoping to get something like Oculus Medium (see video linked below). Are there any alternative solutions for the desired result?

Yes they do work. I Set them up myself. Search Thumb Cap

Oh thanks! I overlooked it because it is not mapped specifically but I can do some logic to make it work.

Thumb Cap I think is a general value for all face cap sensors on the Touch controller. So if FaceButton1, 2 & Thumbstick Cap = 0 AND Thumb Cap = 1 then that sensor is active.
