Uber: thanks man! answering your question, its pretty simple, for the ones in the bags I just made a big enough horizontal lines alpha, and with Standart brush (focal -100) and DragRectangle, I dragged until cover the surface that I wanted. For the detail in water bottle, I unwrapped it before bring to zbrush and for the border I made it straight in the uvs. Then I masked by alpha (vertical lines alpha) and inflated it. thats it, hope it helps.
