it will NOT take you six months because I have a document that explains how to convert MMD from blender to unity to avatar. Also if you look at the file wa (fixed).fbx it's mostly done you just have to follow the steps mention in the manual about CATS (Prepping your Avatar with CATS). You will have to install the CATS plugin as well as the Atlas Optimization plugin to get the ball rolling though
