I'm pretty sure this has already been done, but I decided to give it a go anyways. When used, this LoRA produces an over-the-nose (OTN) cloth gag with reasonable consistency. I found it sometimes results in a over-the-mouth (OTM) gag, some kind of neck covering, or no gag whatsoever. The knot of the gag sometimes shows too, but isn't perfect either. Best of luck!
A weight of around 1.0 seems to be fine
