I am trying to get the bounding box of a node after applying a mesh and I always get the default box Minedge = {-1,-1,-1} and Maxedge = {1,1,1} returned. Is this a known bug? I was debugging and
Try to access the bbox after registering the mesh (or drawing the first frame). Maybe UpdateAbsolutePosition is also enough. Irrlicht tries to update some information only during rendering.
