Are there any deformable / flexible plant assets available for Isaac Sim or Isaac Lab?

Hello NVIDIA Isaac Sim / Isaac Lab team,
I would like to ask whether NVIDIA provides any deformable or flexible plant models that can be used directly in Isaac Sim or Isaac Lab.

Specifically, I am looking for plant assets with physical flexibility, not only visual plant meshes.
I have seen related work where artificial plants were modeled as OBJ meshes and converted into deformable bodies using Isaac Lab APIs.

My questions are:


1. Does NVIDIA provide any deformable / flexible plant assets for Isaac Sim or Isaac Lab?
2. If such assets exist, are they available in the Asset Browser, SimReady assets, Nucleus, or any official sample repository?
3. If there are no ready-to-use flexible plant models, what is the recommended workflow for creating one?
   For example:
   • importing OBJ / USD plant meshes,
   • converting them into deformable bodies,
   • setting FEM / deformable material parameters,
   • configuring collision with robot manipulators,
   • and using them efficiently in Isaac Lab reinforcement learning environments.
4. Are there any official examples or documentation showing how to create deformable objects similar to stems, branches, leaves, or thin flexible plant structures?
   If NVIDIA has any suitable assets, example code, or recommended modeling approach, I would be very grateful for your guidance.
   
   Thank you very much.

there are some assets on simready.com ，but it cost a lot ！

Also grabcad.com was helpful for me, and the assets I used and downloaded were for free :)
