Cannot render the whole URDF model with OpenGL3

[SJTU-gzh]

Hello everyone:
I am having some trouble rendering a robot URDF model in GUI mode with OpenGL3 visualizer. Part of the robot model is visually missing after a specific link, but physically all these missing links and joints can be controlled using p.setJointMotorControl2 (they can also be dragged directly in the GUI). When I use the OpenGL2 visualizer, it seems to be fine.
So I guess something may have gone wrong when rendering with OpenGL3? I would like to have a fully rendered robot model with OpenGL3. Hope to get your advice, thanks very much!
