Well this is standalone pack but you can of course use with pac3 but even you don't need pac3 you can direcly use bonemerge and you can wear this item whatever your pm

is it compatible with pac3?

actualy I can make it phy so easyly but if I got energy I even finished my Kagamine Rin 5 months ago but other projects and so many stuf happend I couldn't keep up to my releases. but that tool can be help you too.

ok turns out this addon fixes my problem with the hitbox for the effect being the blue ring

i forgot to ask, what's the name of the bone that the models attach to?

the only reason i ask is because one of the models i was going to bonemerge one of these on doesn't have the bone to merge it with (also it's shorter than the model's hitbox thing so i can't just overlap it and weld)

Hmm i dont think but it also fit other pms and hl2 biped models you just need bone merge tool for it

yeah i turns out i missed an addon cause the steam interface in a game is so small
but i do have a question, will these ever become props?

question do you have got this 2
All of them in here

and
Team Fortress 2 mounted to gmod?

hey i think you have another bug to fix
because under any type of light the bibs are purple
