the agent model should be excluded from the navigation mesh geometry , will be fixed later when a list is added to the editor.
the internal input geometry list , is not cleared when a rebuild is triggered , the list clear function will be added later (not a bug , purposely left out)
fbx/dae sizes and other settings still need to be set , currently the agent hit position is ignored because of this , remedy : use mdl or wmb file to test the agent model.
slope angle or slope related settings/code are wrong ,it was correct but I changed something and did not notice it at the time , problem is easily seen on terrain , I will fix it later.
you may need to copy directx files from your gamestudio folder in to the tool folder , I have not included them in the redistributed rar.
