When the Samurai attacks an object, the sword determines the cutting direction and the mesh is split into two separate pieces. The new pieces automatically receive physics components so they can fall and move independently.
Setup
Import the Unity package.
Open the included example scene.
Add SliceableObject1 to any 3D object you want to slice.
Assign a Cap Material if you want a different material on the cut surface.
Select the model and open its import settings.
Make sure Read/Write is enabled.
Make sure the object’s Mesh Collider has Convex enabled.
Click Apply in the model import settings if necessary.
Press Play and attack the object with the Samurai.
Important: Enable Read/Write
The mesh must have Read/Write Enabled. The slicing system needs to access the mesh vertices at runtime in order to cut the object.
To enable it:
Select the model → Inspector → Model → Read/Write → Enable → Apply
If Read/Write is disabled, Unity will not allow the slicing system to access the mesh data at runtime, so the object cannot be sliced.
Important: Enable Convex
If the sliceable object uses a Mesh Collider together with a Rigidbody, make sure Convex is enabled on the Mesh Collider.
This is required because Unity does not support a non-convex Mesh Collider on a dynamic Rigidbody.
Select the object → Mesh Collider → Enable Convex
The slicing system also creates physics components for the newly generated pieces.
Requirements
Unity 6 or compatible Unity version
Notes
The system works best with reasonably clean, closed meshes. Very small, extremely thin, or highly complex meshes may produce less reliable slicing results.
