Well actually, working with obj2blb is a horrible way to work with BLB
if you really want to copy a model into a BLB
(Assumind your using blender 2.5)
Make a blender model, use the edit mode and select each vertice, click N, copy the X Y Z of the face into the POSISION of each face
For example




REMEMBER, you must go AROUND the face and select each vertice, you cannot go up to down on each side or something like that, or else the face will overlap
