I don't see how that poses too much of a problem. There's already camo clothing in Dayz that, in certain cases, you are pretty well hidden. There's also the ghille suit that is just outrageous (not in a bad way, it performs as its supposed to.). I've seen people sit in bushes and near tree's with that thing on and I can't distinguish between the two half of the time if they are prone, hell I've walked past people in ghille suits all the time because the textures are literally the same as the grass and bushes. It's like I said, you can't have realism if everyone is walking around as the same John/Jane Doe with the same generic clothing. QFT.
