Found where the bug was.

In create function

_tree->vNode.clear();
  for(std::size_t i = 0; i < 8; ++i)
  {
   child[i] = std::shared_ptr<OcTree>(new OcTree(_tree->pSmgr, subdivide(_tree, i)));
   create(child[i], curr_level + 1);
  }

Should be:

_tree->vNode.clear();
  for(std::size_t i = 0; i < 8; ++i)
  {
   _tree->child[i] = std::shared_ptr<OcTree>(new OcTree(_tree->pSmgr, subdivide(_tree, i)));
   create(_tree->child[i], curr_level + 1);
  }

Damn recursive functions, should step back and learn again about them better.
