Get an observation of rope without picker in sight

[TritiumR]

Hi!
I encountered some problems to get an observation of rope in the task "RopeConfiguraion" without picker in sight.

I have noticed that "pyflex.render_cloth()" will return an observation of cloth where there is no picker.
But when it is applied to "RopeConfiguraion", it returns an all-zero image.

I wonder if there are some functions that could render only the rope?
Or I need to "hide" the picker and use pyflex.render() instead?

Thank you for any help you can offer.
