This is literally just a single button HUD that sets your body to BoM and sets your left arm to the Left Arm Tattoo universal layer channel. It's free.
I couldn't find anyone else using this and I needed it for a mod.
This is ONLY for legacy, it ONLY applies BoM Body Upper to the upper body, BoM body Lower to the lower body and Left Arm to the left arm.
Notecard contents:
The legacy body is a lawless hell pit that only works when there's a full moon and a 98% humidity index.
This is a single-button HUD that you can click to set your left arm to the BOM LEFT ARM channel. It does nothing else.
It MIGHT spit this out into your local chat:
[14:13] //A\\ LEGACY ARM ASYMMETRY APPLIER: Configuring. Please add a notecard.
If it does, it'll still work. Again, legacy is a lawless hell pit and I couldn't get it to stop saying that.
When I was trying to get this to work, I had to switch Legacy huds like 20 times. It'll work when it wants to.
Weeks of search and discussions and frustration with alpha blending on left arm when using any other method. I then decided to give up.
And when I did, I searched via Google for Left Arm Channel in general and one hit was this item on marketplace. Like if some spirit wanted me to get here. Tried it. Works like a charm. Only thing is, you cannot use any 3rd party materials (like with the Sensations HUD). A pity but I can live with that.
So, THANK YOU VERY MUCH!
