This is what you're looking for?
PS: You may have problems with some players skin, I was placing the tats in my sgsm, went ingame and a few players limbs looked a bit messy, Looks like I have to adjust something. I'll repost when I find a solution to my problem. (Not everyone may have this problem)
Also, I would only use the first 2 links if your just interested in the sweat patch, be sure to extract the "plr.details" and anything else that is essential. example: "smparke_arm_tat.fsh" is not essential, however "plr.details" "armbase.fsh" "Plyrtat.viv" are essential, at least from what I've seen without using them.
I didn't extract somethings, and didn't get a desired result.
Ah . . if you wanted the result I have in the screenshots. What you should extract is the 2x armbands fixed. In it you'll see many armXXbase.fsh extract all of those to your sgsm folder, then you'll want to also extract the legXXbase.fsh from the other file.
Leave the armXXbase.fsh, as you already have them.
WARNING: This may or may not be fully compatible with some Tattoos. I However am not having a problem with it, as of now.
UPDATED: Having a problem with some tattoos, still looking into it if it has something to do with a tattoos size . . (Like the default tattoos in game work fine with the patch, but some user created materials make the players limbs look messy) Essentially, because the sweat patch is 2x, the tattoos need to be as well.
