Do some 3D Model - Automation -- 2

We have an existing 3D model of a shirt and 3D parts of the shirt. The parts range from different types of Collars and different types of Cuffs etc. The Main objective for this project is to create an "Automation system or method" (Similar to Photoshop Actions) that will take a provided 2D cloth pattern and subsequently apply them to our existing model and parts. The Programer / Designer is expected enable batch processing on this 3D shirt to overlay any different cloth pattern (provided) and individually export each part of the shirt into an individual transparent PNG (e.g. each of 12 collars) into a folder. The component list for EACH pattern will probably be a total of about 30 - 40 different parts in all including Collars, Cuffs, Plackets, Fit of shirt, Back of shirt, button positions, etc. The final outcome should be a simple file where we can easily upload or select any perfectly repeatable pattern of a cloth, and get an output like an entire folder of all the required parts of the shirt with the pattern all overlay-ed. (Work can be done on any platform but preferred ones are Maya or Marvelous Designer e.g. - But the designer can suggest any other software as long as it delivers the required results.) This will be for an online site that will allow for customization of men's shirts. e.g. [login to view URL] But with much less selection and ONLY for Men's shirts.
