The test case is missing the actual hero mesh, so i replaced it with the ninja from the Bones examples. It didn't work too well, because all i got to see was the sword and some funny looking ground object. However, i got this:
WARNING: You've exceeded the configured triangle limit for the visibility list. Consider adjusting Config.maxPolysVisible!
If you get that too, it explains a lot. Just do what the warning says and see if it helps. Or switch to compiled objects, which won't cause this problem anyway.
