Quick Start

Get your first extracted mesh in under a minute.

Step 1 — Open the Tool

Navigate to Tools → Skinned Mesh Separator in Unity's menu bar.

Step 2 — Assign a SkinnedMeshRenderer

Drag a character's SkinnedMeshRenderer component from the Hierarchy or Inspector into the Skinned Mesh Renderer field.

Step 3 — Find Bones

Click 🔍 Auto-Find Bones to automatically detect the head and shoulder bones from your rig.

Tip

Auto-Find works with most standard humanoid naming conventions (e.g. Head, Shoulder_L, UpperArm_R). If your rig uses non-standard names, assign the bones manually by dragging them from the Hierarchy.

Step 4 — Enable Read/Write (if needed)

If the mesh is not yet readable, click 🔧 Enable Read/Write on Source Mesh. This updates the model's import settings automatically — no need to dig through the Inspector.

Note

The source mesh must have Read/Write Enabled before any extraction can proceed. The tool will log an error in the Console if this step is skipped.

Step 5 — Extract

Click one of the preset extraction buttons:

Button Result
Keep ONLY Head Extracts just the head region
Remove Head Keeps the body and arms, removes the head
Keep ONLY Arms Extracts both arms
Remove Arms Keeps the body and head, removes arms
Keep ONLY Other Part Extracts the bone set in the Other Bone field
Remove Other Part Removes the bone in the Other Bone field, keeps the rest

Step 6 — Save

A save dialog will appear. Choose a location inside your Assets folder and give the mesh a name. The new .asset file will be created there.

Your original character mesh is unchanged.
