 =====Pathfinding on uneven ground=====
-Pathfinding works on slight uneven ground (see '''''tolerance values''''').
+Pathfinding works on slight uneven ground as long as the polygons are 0,5 world units beneath or 4 world units above the BNV.
-For bigger surface irregularities we can use a trick. The problematic polygons can be saved to an dae file and then referenced in the model section as an individual object. Then the <GunkFlags> tag needs to be '''''GridIgnore'''''. Additionally we create a plain (invisible if necessary) under the object so that Oni doesn't think there's a hole.

+* The ghosts must be taller than the highest polygon to walk on. (This has been tested up to a height of 2000 world units.)
 For example this trick can bypass [https://dl.dropboxusercontent.com/u/139715/temp/bad_BNV.png pathfinding problems with pyramids.]
-'''Limitations'''
+'''Symptoms of too small ghosts'''
-On PC this trick works up to a height of 17,9. Between 18 up to 18,9 it works only to some degree: AI can randomly lose pathfinding. [http://youtu.be/pXfOz4sCyPc Here's] some testing footage.
+A) AI can't run at all.
-Another drawback are high jumps, they can break chump's pathfinding. If such AI gets out of view for ca. 2 seconds, it can regain pathfinding.
+B) AI loses PF if tracked enemy performs animations that are out of the pathfinding volume. [http://youtu.be/vfKPzP5hiCo Here's] a video about of the "B" symptoms.
-On Mac it was reported that 20 is the maximum.
