Combining 3D meshes in a single graph

Hello, I am following the next example from the App Gallery:

But I have problems combining different meshes:

I tried to extend the vertex and faces list for each mesh.
I also tried to add a list of data (meshes) to the graph figure like here ( , but the graph results empty.

Hello, I managed to do that by updating the faces indices of the next meshes to the last index in the last mesh. Then I can create an intensity map where each position is a point of each mesh.
