I will be adding content to this and there will various equipment improvements added very soon.

Nothing but original Frostfall backpacks supported for the time being.

Known Issues:
1. If you use 2H weapons you may see your weapon dissapeared and have floating woodcutters axe instead. Fix on it's way.

Installation of HDT Physics patch for backpacks. If you already have any/all required mods installed, skip those steps.
Every step assumes download and install actions.
Simple (no FNIS):
1. XPMS (v1.93a). Be sure to check NoFNIS patch in NNM wizard.
2. HDT Physics Extensions.
3. HDT Equipment.
4. Armed To The Teeth Skeleton (Opt. version recommended). Gives proper backpack position and better overall weapons locations.
5. HDT Physics 4 FFB (look for it in files section of this mod).

Expanded (FNIS):
1. XPMS (v1.93a). Be sure to NOT check NoFNIS patch in NNM wizard.
2. FNIS.
3. Generate new behavior files using SKELETON Arm Fix. For more details look FNIS description or different guides.
4. Realistic Ragdolls and Force (optional, but recommended).
5. HDT Physics Extensions.
6. HDT Equipment.
7. Armed To The Teeth Skeleton (Opt. version recommended). Gives proper backpack position and better overall weapons locations.
8. HDT Physics 4 FFB (look for it in files section of this mod).

You can install extended version of XPMS. In this case FNIS and Realistic Ragdolls and Force are requirements of XPMS Extended 2.06.
You can use main version of Armed To The Teeth Skeleton as well, but there will be more clipping with backpack.
