[Closed] How to export properly vertex normals with maxplus?

Hi guys, after spending a reasonable ammount of time trying to export vertex normals correctly using maxplus I think I’ve got stuck. First of all, let me show you a little render of the vertex normals I’m getting from maxplus.

Now, here’s the code I’m using to export the normals:

def dump_geometry(node):
    obj_state = node.EvalWorldState()
    obj = obj_state.Getobj()

    try:
        triobj = obj.AsTriObject()
    except Exception as e:
        # import traceback
        # traceback.print_exc()
        log("dump_geometry: geometry not available")
        return None

    tri_mesh = triobj.GetMesh()
    # tri_mesh.GetNormalsBuilt() # To check whether normals need to be built
    tri_mesh.CheckNormals(True)

    normal_count = tri_mesh.GetNormalCount()
    vertex_count = tri_mesh.GetNumVertices()
    face_count = tri_mesh.GetNumFaces()

    faces = []
    vertices = []

    # Faces
    for i in range(0, face_count):
        face = tri_mesh.GetFace(i)
        for k in range(0, 3):
            faces.append(int(face.GetVert(k)))

    # Vertices
    for i in range(0, vertex_count):
        vertices.extend(Convert.point3(tri_mesh.GetVertex(i)))
        vertices.extend(Convert.point3(tri_mesh.GetRenderedVertexNormal(i)))

As you can see in the previous snapshots, all vertex normals are correct but some of them are not, for instance, the vertex normal on top of that pyramid is broken… so I was wondering if anyone could explain me how to fix the maxplus code to handle that.

Also, there is this thread in autodesk forums talking about some related issue but I didn’t understand very much if it’s related to my
issue or not.

Hopefully you can advice here.

Thanks in advance!
