Building DisplayMaterial questions

Thank you for your reply. I think it might be a problem with my grid? Resulting in the rendering not meeting the requirements?

The key part of the pipeline👇

        self.eddm  = rh.Display.DisplayMaterial(
        )

        self.eddm.IsTwoSided = False

        self.eddm.BackDiffuse = sd.Color.Red

        self.eddm.BackTransparency =1


    def DrawForeground(self, e):
        """
        Draw_e
        """
        try:

            if not self.Drawing_Meshs is None:
                for me in self.Drawing_Meshs:
                        e.Display.DrawMeshShaded(
                            me,
                            self.eddm
                        )

            pass
        except Exception as ex:
            print("me",ex)
