On miss the raycasters aligned rotation is inverted from what is expected. a raycast commonly only collides with surface normals that face towards the caster, because of this it is pretty standard that the onMiss rotation defautls to a normal direction that faces the caster, but the VRCRaycast seems to invert this behavior. where on miss the result has a normal direction facing away from the caster.
if the raycaster was used for range limited grounding behavior this would result in the object flipping upside down the moment the raycast no longer hits the ground which is generally undesired.
Either flipping the normal or providing a value that allows us to specify a onMiss rotation would resolve this issue and allow for more specialized usecases too.
