         <add name="Scale" type="float">The scaling factor to quantize the MOPP: the quantization factor is equal to 256*256 divided by this number. In Oblivion files, scale is taken equal to 256*256*254 / (size + 0.2) where size is the largest dimension of the bounding box of the packed shape.</add>
