+;Plane
+It appears that the plane is ignored by the engine. In particular if a side has adjacencies then it has ghost quads and any quad has an associated plane. Sometimes the ghost quads are inside the BNV (instead of being on the edge) and in that case the quad plane is different from the side plane.
 ;[[OBD:AKAA|AKAA]] range
 :These 2 fields make up a range of "adjacencies" (see [[OBD:AKAA|AKAA]]). If the fields are equal then the range is empty.
-;Unknown fields
-:All the "unknown" fields seem to be ignored by the engine: setting them to anything (0, -1, value bigger than [[OBD:AKBP|AKBP]] or [[OBD:AKAA|AKAA]] count etc.) apparently has no effect on the game.
