You can now open the tool window under **tools** -\u003e **Mesh Combiner**.\n\n## Usage\n\n1. In the Unity Editor, select one or more GameObjects (any of them may have children with MeshFilters).\n2. Go to **Tools → Mesh Combiner** to open the combiner window.\n3. Toggle options as desired:\n4. \n    * **Strip inward-facing triangles**\n    * **Cull mutually facing triangles** (and adjust the **Pair distance threshold**)\n5. Click **Combine Selected**\n6. \n    * Selected meshes are hidden under an `_oldMesh` group\n    * A new `_combined` GameObject is created, with combined geometry, materials, tags, layers, and colliders\n7. To revert, select the combined GameObject in the Hierarchy and click **Uncombine**\n\n    * Restores original meshes, hierarchy, transforms, and deletes the combined object\n\n## Contribution \u0026 Known Issues\n\nAny contribution is welcome as there is still a lot to improve and add:\n- Better readme with more images or gifs\n- Better workflow for editing merged meshes. Right now you have to Uncombine -\u003e edit the objects -\u003e Combine again\n- More and better optimisation methods\n- The duplicated colliders dont mirror tags and layers so they have to be set manually\n- Merged Objects have all the Materials of the old Meshes, even if they are duplicate. This leads to performance and lighting issues\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstefaaan06%2Funity-mesh-combiner","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstefaaan06%2Funity-mesh-combiner","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstefaaan06%2Funity-mesh-combiner/lists"}
