In 3d studio max go to Script > listener or hit F11 then select all objects and in the white field delete everything and type : deleteModifier $ 1 and hit Enter.
Yeah, but script is easier/faster. Select all the meshes, go to the Utility panel, click the More... button, choose UVW Remove and click OK, then click Materials.
Does anyone know if max has an equivalent to the Grease Pencil found in Maya/Blender? I know there were some scripts floating around years ago to do it, but maybe its got a built in version by now?
