Error in bounding box computation

Hi there,

can you take a look at this tutorial, it computes aabb’s at different steps:

    # Calculate the bounds of the prim to create a scatter plane of its size
    bb_cache = create_bbox_cache()
    bbox3d_gf = bb_cache.ComputeLocalBound(prim)
    prim_tf_gf = omni.usd.get_world_transform_matrix(prim)

    # Calculate the bounds of the prim
    bbox3d_gf.Transform(prim_tf_gf)
    range_size = bbox3d_gf.GetRange().GetSize()

    # Helper function to get the combined bounds of the forklift and pallet
    bb_cache = create_bbox_cache()
    combined_range_arr = compute_combined_aabb(bb_cache, [forklift_prim.GetPrimPath(), pallet_prim.GetPrimPath()])

In the end these are wrapper functions calling various usd bbox api:
