I created this mod for myself and decided to share. I wanted to learn how to take modder created gear and make them like vanilla gear, fully integrated into the game world, but with support added for popular mods like Frostfall and WACCF. I am releasing esp replacers for NewerMind43's excellent ESO Breton Knight, ESO Nord and ESO Altmer armors, as well as his "Imperial Assassin armor". Imperial Assassin ( https://www.nexusmods.com/skyrim/mods/55505 ) hasn't been ported to SSE, so I recommend you convert the meshes using "Cathedral Assets Optimizer" , Mesh > Process meshes > Necessary optimization + Always process headparts. The mesh and texture resources from NewerMind43 are still required.

Advice to tinkerers: The process I have followed is:

1. Open mod in xedit along with Frostfall, CCOR, WACCF, and the Unofficial SSE Patch. Remove wind edits and unused records. Forward data (usually only needed for Worldspace and Cell edits).

2. Decide what tier the mod added items are equivalent to, and change stats where necessary.

3. Add appropriate Frostfall and WACCF keywords to the individual pieces of equipment (I recommend also copying the records you intend to use into the weapons/armor esp Keyword section).

4. Run the script "Skyrim - Make Craftable" to add crafting recipes. Fix any fubar condition data, add Perk requirements to condition if needed (eg 1, HasPerk, SteelSmithing).

5. Run CCOR Break it Down v2_0 to add Breakdown Recipes.

6. Run CCOR Compatibility Script v2_0 to add CCOR conditions to the recipes.

7. Run ALLA_AutomatedLeveledListAddition to add mod items to level lists (be careful of non helmet headgear, the script can error out; if this is happening run the script on just all the non headwear items, and them on the headwear alone). Removed inappropriate levelled lists and edit level placement if off. Note: this script can apparently add crafting recipies to, but when I tried either did nothing or just added crafting and not breakdown/tempering.

8. Compact records, add esl flag.

I have altered the statistics of some of the equipment, mostly to a small degree. The only exception was the Breton knight set, which was nerfed. The other sets are low tier (leather, steel, elven light), but Breton Knight has medium-tier tier, so I reduced it back to the area around leather and light elven. The Nord armor is still Male only, but will use vanilla Steel armor meshes and textures when equipped by females. Vice versa for the ESO Altmer armor, except I changed it to show as leather armor on male. Skyrim doesn't have gender specific levelled lists, so this is the best practice for creating gender specific equipments, and was what NewerMind43 did (I believe that if no resource is specified for a gender, then the appropriate body area will be invisible if the armor piece is equipped). ALLA_AutomatedLeveledListAddition can apparently handle this automatically as long as you as a "FemaleOnly" or "MaleOnly" keyword to each piece (the FormId of the keyword doesn't matter).

Lastly, you might prefer Gamwich's retexture of the ESO Nord armor: https://www.nexusmods.com/skyrim/mods/69307
It is still oldrim only, so you need to convert the meshes (I believe the meshes are needed because Gamwich only uses one of the two very similar lower body textures).

Credit to NewerMind43 for turning 2d artist conceptions into 3d game items. That is way beyond my technician level skillset.

Apologises for the bad merged plugin. I used the old XEdit script to create the merge, but it got "confused" and messed up a lot of the entries. Run "Check for Errors" after creating a merge. I ended up redoing the merge in ZEdit, it it reports no errors. I am still learning and make mistakes sometimes.
