sectional arm alphas BOM/System layers

I've bought quite a bit of alpha packs and its annoying seemingly never having enough to alpha out parts of the arm i need. So i created 12 alphas cutting off different parts of the arm in sections. FYI i used the sluv maps to create these, so alpha edges may not be perfect for every mesh body. Most noticeable around the hands

These are all bom/system layers, so your mesh body must be bom enabled.

main alpha sections:
- shoulders
- upper arms
- forearms
- elbows
- wrists
- hands
- whole arm

the other variations in this pack are combos of the main alpha sections (ex: upper & forearms).
