I need armor stats only from some armor-weapon filter patch. How do I edit it, eventually how importing part of this patch only into Wrye Patch?

It's generally impossible to edit a filter patch unless you are the maker of it, because you need to collect every single file that is mastered by the filter, some of which might be personal plugins not available online.

I was afraid such answer. So, generally, there are two ways - to get all plugs pointed in master list or to create own "anti-patches". Pity. You killed my hopes but thank you Thomas.

This is newbie question - I've never done it. There is possibility to export some parts of inactive plug to file in Wry Bash and to use it building Wrye patch. Am I right?

You can try by creating one or two dummy .esp and .esm files, then copy-pasting them as many times as the needed masters, then renaming each one to the master the filter mod needs. It should be possible to view and edit stuff from it in TES4Edit then, ignoring all the 'injected record' messages.

HA! Very good idea! Thank you much. I must try it .

Clever solution....

Also out of curiosity, which filter are you about to victimize?

Hm. Your one. TIE Weapon + Armor Filter.esp.
