RDNA's freestuff can be daunting to go through because there's no way to search it :) The special edition includes several Mike faces and more than twice as many morphs...if you didn't get faces, you got the old version. I forgot though that its still live from my freestuff page here! Click my username and visit my freestuff page and you can get the updated zip. The wrinkles are folds in the model. You can try using (shudder) magnets to smooth them I suppose. If a smooth chest is a must using Mike without a body suit may be better for your situation. You can distribute any textures you create yourself free or for sale, unless its a copyrighted characters suit or something. You can't sell a Superman outfit but they won't freak out if you give one away for other fans to use.
