This patch builder crawls your entire load order and builds a patch that merges all your armor mods. I made it especially for my Skimpy Clothes mod but discovered that it's more generally useful. 

What it does

Lots of mods add keywords to the armor, and some ignore the keywords added by other mods. The result is that you lose some important keywords--like warmth, if you're running in survival mode. This patcher will create a new override for each armor that contains all the keywords added by any mod in your load order.

Tools like Wrye Bash don't do this because they're trying to be responsible. This tool just gives you all the keywords, regardless. There are a few cases where that gives "incorrect" results--like an armor classed as both Hide and Ebony, or as both Light and Heavy. But those errors are a much smaller problem than fur armor without the Warm keyword, if you're running in Survival mode.

This tool also has special handling for Skimpy Clothes to add the Revealing keyword to all armors that ought to have it. 

How to use

1. Install and learn to run SSEdit, set up to run under MO (if you use MO). The S.T.E.P. Guide will help you get it set up. (You don't have to install the STEP mods! Just follow their instructions for getting xEdit working under MO.)
2. Copy the file BD_Armor_Patch_Builder.pas and BDScriptTools.pas from the above link to "<Your SSEEdit folder>/Edit Scripts"
3. Start SSEEdit with your entire load order selected.
4. Right-click in the left pane and select "Apply Script"
5. From the "Script" pulldown, select "BD_Armor_Patch_Builder"
6. Click "OK"
7. Let the script do its thing. It will create a new mod called "BDGearPatch.esp". 
8. Enable this plugin and you're good to go. It's ESL-flagged so it won't take space in your load order.

Notes;

• If you're running with MO, the new plugin will be in your Overwrite directory. You probably want to move it to a new mod just for patches and overrides.
• The new plugin will specify every mod in your load order with armor as a master. This is so LOOT will sort it after all those mods. You can clean the master list if you want to, but then you'll have to make sure LOOT doesn't do something stupid.
