About tranform base shader on BatchingMesh

Hello everyone, I’m new to threejs. So I have an idea, I have a scene and a model (the model is processed with Cell Fracture in blender to get the fragments). I then add this model to the scene, and move them. Everything works, but there are over 300 draws.

Then I learned about BatchingMesh, but I can’t move each fragment of model in the vertex shader, please help me. Thank you for reading this article
