Easy Merge Bone

Merge selected bones into one bone and automatically combine their vertex group weights, all in a single click.

Simplifying a rig usually means merging bones, and doing it by hand means deleting bones, re-parenting children, and cleaning up vertex groups afterwards. Easy Merge Bone does all of that for you.

How to use

• Step 1: Select your armature and enter Edit Mode.
• Step 2: Select the bones you want to merge (at least 2 bones from the same parent–child chain).
• Step 3: Open the sidebar (N) > Easy M Bone tab and click Merge Bones.

Features

• One-click merge – each selected bone chain collapses into its top bone, which keeps its original name.
• Automatic weight merging – the vertex group weights of the merged bones are added together (clamped at 1.0) into the top bone’s group, and the leftover groups are removed.
• Works on all bound meshes – every mesh parented to the armature or using an Armature modifier is updated.
• Smart bone length – the merged bone is extended to reach the end of the chain.
• Automatic re-parenting – child bones outside the selection are attached to the merged bone, and connections are kept where possible.
• Multiple chains at once – select several separate chains and merge them all with one click.
• Undo support – one undo step reverts the whole merge.
• Clear feedback – a report shows how many bones were merged and how many vertices were re-weighted.

Requirements

• Blender 5.2.0 or newer
