VRTK allow collision detection by adding the VRTK_HeadsetCollision, VRTK_BodyPhysics, VRTK_HeadsetFade and VRTK_HeadsetCollisionFade scripts into Unity.
This works so that in VR when I walk through a wall, the scene fades to black as expected.
However, I would also like to trigger events when I enter certain spaces in VR. Usually I would use a Unity BoxCollider with IsTrigger checked, but unfortunately, VRTK seems to ignore the IsTrigger value as it still fades to black when I enter the "zone".
How can I trigger a Unity event when the VR player enter's a zone with VRTK?
