I have been trying to figure this out un-successfully, on my guardian I have a Ram Horn Witch mod installed and it all looks great except the legs clip massively through her boots. I tried to add pgw_10_ub_0020.pac to my "characteraotexturelist.txt" found inside of my Paz > files_to_patch > character folder with no luck. I have also looked for a partcutdesc.xml file but I ran into the problem of having 4 of those and when I tried installing the above into each of the 4 it did not fix the clip. For reference in the partcutdesc.xml file I would type "<File>1_pc/11_pgw/armor/10_lowerbody/pgw_10_lb_0020.pac<File>" or "<!--- <File>1_pc/11_pgw/armor/10_lowerbody/pgw_10_lb_0020.pac<File> -->" and have not had any luck.
Has anyone been able to get the legs to look right in the Ram Horn Witch mods? What did you do? Where should we find the partcutdesc.xml file so I can delete these other 3? Thanks for any guidance!
Try the partcutGEN tool from undercovertpervert and add pgw_10_?b_0020.pac to your list in partcutdesc_exclusions.txt that will be generated by the tool. It should tell the game to only NOT cut ub and lb for that outfit for guardian (if you have an edited version of the armor that shows skin in the ub and lb part of your guardian).
That tool saved me a lot of grey hair pulling trying to mess with the partcut files.
If you want to go the manual partcut editing route, make sure the lines where you apply the commands to cut or not cut actually pertain to the foot part of the armor (see the /cut relation at the bottom of the partcutdesc.html file to see what it's programmed to cut or not cut). For instance, if you're modifying a line that's in the "ub cuts" part, it will have no effect on the foot parts of the armor.
Sometimes, some cuts are defined in strange, unintuitive parts though. Like hands or sho that would control cuts on foot or breasts for instance. That relationship will still be true when using the partcutGen tool, so you'll have to experiment with other parts if you find that you have holes in ub despite telling it to not cut ub for example.
hope this helps, have fun in your modding edventures =)
P.S. If all fails, it means that the clipping can only be fixed with a mesh edit (modifying the pac file).
There is a thread explaining the troubleshooting steps to fixing holes and clipping to see if partcut will be able to solve it or not. Basically, start by using a vanilla partcut file (delete your modified one) and see if the issue is fixed. If it is, then it means that partcut can save you. Otherwise, you'll have to find other workarounds like editing the mesh or the _ao file of an underwear you wear regularly to erase that part of the clipping foot.
