“Please consider purchasing the asset to support the developer.”

Create new sub meshes inside Unity for any model. Assign your materials with ease.

✔️ Super easy to use.

Draw on the mesh and then pick a material. Done.

✔️ None-Destructive workflow

Automatically generates a new mesh asset (.asset file). Your original asset remains the same.

✔️ Skinned Mesh Support

Keeps all your bone weights and animations intact.

⚠️ Please notice that the .obj file format does not support bones or animation. Thus that information can not be exported as obj.

✔️ Brush for high-poly meshes

Though you should keep it under a hundred thousand triangles for best performance.

✔️ Undo/Redo for selections

✔️ .OBJ Export

In case you need to pass your new mesh around.

✔️ Full Source Code included!

I publish this asset with full source code because as a developer I know how annoying it is to not have source code access. If you like it then please remind others to purchase the plugin. Don’t just copy and paste it everywhere. Thank you ❤️

✔️ Supports Unity 2020, 2021, 2022, … LTS

⚠️ This is NOT a runtime system. It is EDITOR only.
