I used arm26.xml from mujoco/models. It shows well in mujoco.

But when I try to use it in genesis,it only shows a simple plane,lack the entity i added.

My whole code about entity is:

plane = scene.add_entity(
    gs.morphs.Plane(),
)
franka = scene.add_entity(
    gs.morphs.MJCF(
        file='robot/arm26.xml',
    ),
)

genesis version latest.
