=====Pathfinding on uneven ground===== | |||
Pathfinding works on slight uneven ground (see '''''tolerance values'''''). | |||
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. | |||
For example this trick can bypass [https://dl.dropboxusercontent.com/u/139715/temp/bad_BNV.png pathfinding problems with pyramids.] | |||
=====Debugging (OniSplit v0.9.93.0+)===== | |||

** the original ghost quads can't be seen, Neo: "they are not included in the octtree and bsp tree" | |||
** to see them you must use the -debug option in the level creation command (available with OniSplit '''v0.9.93.0+''') | |||
