what is Global_chr.s3d affect.

[AbstraceHaze]

i running texture hd 4x.
i installed after eq classichd

now im having issue with spirit wolf form messing up, the the whole model is clipping through itself, butt in face legs from other side overlapping, its weird. noticed that is the only issue so far, but while trying to fix it i saw the elemental form update which looks neeto.
my problem is the file size from classic hd is 80 mb, and the update to elemental is 77mb for Global_chr.s3d,

will changing this Global_chr.s3d for elementals affect a lot from my classic hd?
trying to figure out what changes Global_chr.s3d affects. it looks like it affects like all models therefor removing all class updates vs just updating the elementals which i dont want.

the elementals i want are https://wiki.project1999.com/Highres_4X_HD towards the bottom, but don't wanna lose the changes classichd offers.
any help please.. can i overwrite the https://wiki.project1999.com/Highres_4X_HD file for elemental or am i missing out on a plethora of other changes to races classes.
no where is it written that i can find at least what Global_chr.s3d affects specifically but it looks like a ton on 1 post and i rather have the ton fixes vs just the elemental update. any help please.
