Remarks
Returns the most opposing face. Index of the most opposing face
Parameters
| Name | 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. |
