Steps to Reproduce

If possible, provide a script triggering the bug, e.g.

# code snippet triggering the bug
import genesis as gs
gs.init()
scene = gs.Scene(show_viewer=False)
broken = scene.add_entity(
    gs.morphs.MJCF(file='attachement.xml'),
)
scene.build()

Make sure to attached any needed assets (here attachement.xml)!

Expected Behavior

我在obj文件中分析过数据，总共是有529个点，然后f中索引最大的点就是529。没有超出索引
