Description

Reading glTF containing nested scene nodes with a single child leads to lost hierarchy details in produced XCAF document.

Steps to reproduce

pload MODELING OCAF XDE VISUALIZATION
box b 1 2 3
incmesh b 0.1
compound b c
compound c cc
XNewDoc D1
XAddShape D1 cc
SetName D1 [XFindShape D1 b]    "box"
SetName D1 [XFindShape D1 c]    "comp1"
SetName D1 [XFindShape D1 c]:1  "box_inst"
SetName D1 [XFindShape D1 cc]   "comp2"
SetName D1 [XFindShape D1 cc]:1 "comp1_inst"
XSave D1 "test.xbf"
WriteGltf D1 "test.glb"

ReadGltf D "test.glb"
Xdump D


Output:
INSTANCE COMPOUND 0:1:1:1 (refers to 0:1:1:2) "comp2"
PART COMPOUND 0:1:1:2 "box"

Free Shapes: 1
INSTANCE COMPOUND  0:1:1:1 (refers to 0:1:1:2) "comp2"
