Defining a Big geometry in one file and want from splishsplash to recognize all the parts about splishsplash HOT 4 OPEN

Here is also some information about input file

from splishsplash.

This is not intended in SPlisHSPlasH as each "RigidBody" entry defines one rigid body. Either you define one rigid body per closed geometry part, which in your case might be unpractical, or I would recommend to use a Python script to define the scene. In this case you can simply loop over all geometry parts. However, you have to subdivide them.

Thank you for your response.
I have another question. I want to make the ice floes dynamic but also I want constrain them to avoid specific rotations.
How should I do that?

from splishsplash.

SPlisHSPlasH uses the PBD library to simulate dynamics rigid bodies. You could extend this library and implement a constraint which constrains the rotations.
