Warning

The steps order is very important because if you directly do a fusion between the inflated mesh and the map, then the result will be wrong. In fact the white mesh and the inflated mesh are two meshes sharing the same structure (number of vertices and polygons), only the location of vertices differ, so they can be assigned the same textures. But 3D fusions for mesh-map and inflated mesh-map do not produce the same result since in a 3D fusion, the 3D location of points is actually taken into account. So you have to fusion first mesh and map to make an activation texture processing the correct points location, and then report this texture onto the inflated mesh in the second fusion (textured surface).
