 ;General
-:BNVs are volumes that have a [[OBD:AKVA 0|pathfinding grid]] assigned to them. The grid itself is in the RAW, while its overall parameters are in the DAT.

 ;0x00 - [[OBD:AKBP|AKBP]] tree
 :This binary space partition (BSP) tree is used to check if a point is inside the BNV. A list of BNVs that can potentially contain a point is found using the environment octree (2nd [[OBD:IDXA_AKOT_2|IDXA]] of the [[OBD:AKOT|AKOT]] + [[OBD:OTLF|OTLF]]).

 :BNV 165 in level4 (far side of tarmac, behind the fence) has a non-zero X-Z grid size but no RAW data.
 ::Notably, that one BNV also has the 16 flag set at 0x5C (see below).
-:The grid usually "bleeds" outside the (x,z) extent of the BNV.
+:The grid's alignment on the "floor" of the BNV's AABB is defined by the x and z offsets in tiles (at 0x48 and 0x4A).
-:The amount of bleeding is defined by the grid's size (in tiles) and by the size of a tile.
-:The grid seems to be always centered of the "floor" of the BNV's AABB (see above).
 ;0x5C - Floor and ceiling
 ::(typical environment requiring this feature is compact staircases)
