What Seach said. In particular, machinery and insects and such wouldn't really require WMing. If you're composing static imagery with pre WM figures and are unhappy with certain deformations, you can always export the offending posed figure (export: weld body part seams, uncheck include existing groups/ import: weld identical vertices) to an external modeler, or use the morph brush, to fix any nastiness. Also, using a welded mannikin in your final composition, cuts down somewhat (or alot) on scene overhead... I usually just hide the original figure just in case I want to make some changes. Keep in mind you will have to reapply your figure materials to the mannikin, I just create a .mc6 prior for such purposes... the uv's and material groups are retained in the prop.
