help me to free some memory

i’m trying to dispose of invisible geometry buffers, materials and textures to release memory. in the function changeVis (objNames, bool) I added

        if (!bool) {
            var meshArray = obj.resolveMultiMaterial();
            for (var j = 0; j < meshArray.length; j++) {
                meshArray[j].geometry.dispose();
                meshArray[j].material.dispose();
            }
        }

and this disposes of geometry buffers and materials that are not visible at the current moment. help me to dispose of invisible textures
