BACK UP YOUR FILES FIRST or remember where the original files are in their zip folders...
Added pictures to kinda help, when adding bones to the xml files do not use the numbers and letters inside the brackets [###] as they are in Nifscope.
recommend Notepad++ but you can use Notepad or GEdit or whatever
open ALL your .xml files then replace ALL "triangle" words in the "<per-triangle-" "</per-triangle-" to "vertex"
add bones to the collisions like "<no-collide-with-bone>NPC R Finger00</no-collide-with-bone>" for less clipping
the bones used will be what you will find in Nifscope when opening the body "NiNodes"
stumbled apon the HDT Wigs but tired of the hair swinging through your neck and shoulders?
"<per-vertex-shape name="group_1">
<margin>.5</margin>
<prenetration>.02</prenetration>
<tag>hair</tag>
<no-collide-with-tag>hair</no-collide-with-tag>
<no-collide-with-tag>Body</no-collide-with-tag>
<no-collide-with-tag>Lbreast</no-collide-with-tag>
<no-collide-with-tag>Rbreast</no-collide-with-tag>
<no-collide-with-bone>NPC R Clavicle</no-collide-with-bone>
<no-collide-with-bone>NPC L Clavicle</no-collide-with-bone>
<no-collide-with-bone>NPC Pelvis</no-collide-with-bone>"
thats right, change them "triangles" add some "bones"
got male and female jigglies but OMG the hands are clipping where they SHOULDNT be?
add some bones and adjust the "prenetration" (yes, it is spelled right...) oh and dont forget to change them "triangles"
i DONOT know why it makes a difference on the "triangles" and "vertexes" but the link that explains it is below.
i have not found any negative impacts from doing this but of course like always make a back up or dont lose the original files...
Treota over in LL has a better and more explained write out which is where i learned alot of this from. right HERE
I hope this helps as it has helped me tremendous, im running male/female full body HDT + collisions, a few HDT wigs and some clothes. When not in Solitude i get bout 40-50 FPS
