Hi, I've tried searching and checking the pinned threads and tutorials but I couldn't find an explanation

I am making a recolor of a hair and including the mesh as allowed by the creators TOU. When I look in the warehouse tab, there are 48 almost identical geometry parts. The only thing that changes is the instance # and occasionally the group #. This seems really high and it takes up the majority of the file size. Why are there so many parts? Is there a way to trim it down? There are 40 swatches, 4 LODs(0-3) however the mesh is the same for all LODs.

Hi. Every lod of maxis hair contains 3 meshgroups ( base shape and hat chops).
3 x 4 = 12
To make alpha hair and avoid sorting issues, one separates the areas of the hair that need transparency, adds new meshgroups for them, and assigns a different shader to them.
3 x 2 x 4 = 24
It is possible that this is a merged package with hairs for masculine and feminine frames (or children).
3 x 2 x 4 x 2 = 48

You can do things like remove the added meshgroups from lod2-3, but it is best not to, you’d need to remove them in multiple places.

What I understand is, Bottoms such as pants have 3 parts to be compatible with any boots, then you got to state in Region Map if you want to boots to go ontop or under the clothing.
Toddlers have 4 parts which no big deal, just another part to deal with.

Although why more than 1 part for tops puzzles me, I get away with just 1 part, but meshes like ymTop_Pajamas has 7 parts.

Op is asking about a specific hair package.
but to clear some things up:
1). Bottoms are made from 3-4 meshgroups, the difference is in length. If they go below ankles, they must be affected by foot bones and have a separate meshgroup for that area;
2). Tops are made of multiple parts to hide accessories. This is done to prevent necklaces and bracelets from clipping into tops.
