Yes please! For body hair problem - it's result of UV islands between torso and legs being different in size, and fix is reworking hair textures taking this point into account.

I'm sorry for the lack of important details, this post is related to TBSE-based bodies and only waist/wrist seams, we are trying to make W25 compatible with Highlanders =)

I have w25 ivcs hands modpack for this purpose =)

You can fix it with vfx editor (it will give you model pmp, add it to main modpack)
