Vertex Format subversion 1 scales bone joint weights range of 0 to 255. This seems to be a MS3D documentation error (since subversion 2 and 3 use 0 to 100) or an error in Milkshape 3D 1.8.5 beta 1's MS3D loader. Need to check if should change subversion 1 to be 0-100 like subversion 2 and 3. Ideally by testing an older version of Milkshape 3D.
If it's an issue with newer Milkshape 3D loader should change default exported vertex subversion to 2.
Changed default vertex subversion (for models with multiple bone joint influences per-vertex) to 2 which renders correctly in MilkShape 3D. 389cf8879e6cc92611a4869be4c44ccae1ce2114
