Node has other boundingvolume than the debugger renders

this one is weird.

i tried different bounding volumes, but the bug remains. the volume is clearly above the terrain, but in my code, the worldbound is a different boundingvolume (in my case, a box) which is NOT drawn but used for my terrain collision check.



:?



i know which node has which bounding volume, but why aren't all drawn?
