Creating Substance Painter masks based on Blender Vertex Maps

[MiguelB]

If you are trying to create masks for a complex Blender mesh in Substance, This is how youi would do it:

1. Set up your vertex coloring areas in Blender, build your UV map, and export to FBX.
   

   

2. Import the mesh into Substance, and then bake the mesh.
   

3. Select only the ID, then choose to “Bake BODY Mesh Maps.”
   

4. You’ll now have the mesh bake matching the vertex coloring for that specific material. Choose to view by ID if it’s not showing by default.
   

   

5. Add a fill or smart material, then add a mask with color selection.
   

6. Select “Pick Color” at the bottom, and then just pick the vertex color you wish to apply this fill/smart material to.
   

Now you can build a texture map the same as you would do in Blender or Godot or UE4 if you were using vertex colors.
