How to get submeshes by name?

[hit2501]

Hi, I was playing with a model exported from Blender and I can retrieve its submeshes with:

var my_model = newMeshes[0];
var my_submesh = my_model.subMeshes[0];

But now I would like to know how can I retrieve a submesh from its name instead its number (like I can see in Blender).

Can anybody help me?

Thanks in advance.

Not sure what you are seeing in Blender, but submesh does not have a name.  You might be able to something to retrieve by corresponding material name.  Going the opposite direction is

let matName = my_model.materials[my_model.subMeshes[0].materialIndex].name;

getSubMesh(mesh, name) {
    let mat = mesh.materials;
    let idx;
    for (let i = 0, len = mat.length; i < len; i++) {
        if (mat[i].name === name) {
            idx = i;
            break;
        }
    }
    return idx ? mesh.submeshes[idx] : null;
}

Thank you JC, yes, I think I must recheck the documentation but the material (and subMaterials) thing helped me to achieve what I was looking for. Thanks
