Installed this mod on latest Black Mesa 2 days ago. In general it is playable. However it have noticeable count of object collision and moving issues. Large slowly flying objects like barrels, cones etc. often either slide away in impossibly long distances or begin jerking and dancing around confined spaces. Held objects like barrels and boxes on release often fall though floor. Enemies when killed also often fall through floor and disappear. Grenade using is not possible at all - grenades on throw fall through walls and floors and explode somewhere outside map boundaries. This need toe be fixed.
