Marvelous Designer 8 now allows you to trace the UVs of models to create custom garments in a modelling program which is great for making sci-fi models with padding but also great for texture artists.
You can also just import single elements in order to keep things more procedural but I find it faster to model more complex textures.
Also let me know if think medium is good place for these text based tutorials. I am trying to find out the best place to post text based tutorials with lots of images so if you have suggestions let me know!
