Note:The entity won't block nav areas automatically on spawn (except in ). It is best practice to have eitherBlockNavorUnblockNavinputs sent withOnMapSpawn.Warning:Entity's AABB is used for blocking nav areas, so clipping or rotating brushes does not change a brush's size as one expects.Diagonal walls will always be ignored, as it will take the furthest out corners of the diagonal walls and create one huge box around all of it. That box will be your brush entity.
