Returns

Index of the most opposing face

Parameters

Parameter	Description
Position	local position to search around (for example an edge of a convex hull)
UnitDir	the direction we want to oppose (for example a ray moving into the edge of a convex hull would get the face with the most negative dot(FaceNormal, UnitDir)
HintFaceIndex	for certain geometry we can use this to accelerate the search.
