In the current version of RCareWorld, we use Obi as the backend for setting up SoftBody items. We recommend you read Obi’s manual for more details.

To control a soft-body item, attach BaseAttr to it, and you can have access to the basic properties of the item.
We are currently working on integrating Taichi-Unity into RCareWorld. This will allow the users to use MPM for simulating softbody items.
