What is MeshFlow Studio?

MeshFlow Studio is a free browser tool by KAG3D for visually splitting 3D character meshes into multiple material slots. Load any GLB file, paint different regions with colors to define material zones, and export the mesh with separate material slots.

Do I need Blender to use MeshFlow Studio?

No, MeshFlow Studio runs entirely in your web browser with no download or software required. It is a browser-based alternative to manually assigning material slots in Blender.

What can I do with the exported multi-material GLB?

The exported GLB with multiple material slots can be used in Unity, Unreal Engine, Godot, Blender, Three.js, and any 3D software that supports multi-material meshes, allowing different textures or shaders on different parts of the model.
