Simple MeshRenderer Combiner
MeshCombiner — Mesh Combining
Merge many child renderers into fewer draw calls.
• Handles purely static hierarchies and mixed static + skinned setups
• Per-material sub-mesh grouping — one sub-mesh per unique material
• Full blend shape transfer with optional namespace prefixing to avoid
naming collisions when combining multiple skinned meshes
• Non-destructive: source renderers are deactivated, not deleted —
Undo Combine restores the original setup instantly
• Export combined result as FBX file + Unity Prefab + Materials +
Textures (requires the free FBX Exporter package from Package Manager)
