well you just create a text document file and put the name of parts of zack (pick skeleton of zack open in kimera and put the name of p files of zack skeleton in text document) after open the battle skeleton of cloud (rtaa) and go replacing the parts one in one (you need patience) and go resize.
after you replace the parts and resize them click on save model and the name you put rtaa....remember,kimera have a crash when you compile multi bones in a single part so you click no when kimera say this.and other thing:field parts are smaller what battle parts.
