Before I go further, I should mention  Hdiddy's Essential Downloads to Get Started has given me some guidance to prevent this new install from being a dog's dinner.

When installing mods for the game, I have found JSGME Mod Manager to be a useful tool. This utility will install the mods and also allow for these mods to be uninstalled. This is very useful when troubleshooting a bad installation . It can also help keep the number of addons, skins, bodies, models and poses to a manageable size. It is not too hard to learn and use once you understand the game's directory structure. My 'Eureka!' moment came fairly early in the learning process.

I now have the base game, update and Hook 5 installed and working, the next step is Xbody. This will allow you to manage model body types and create hybrid bodies with several different models.

At this time of Blogging, the latest version is XBody Female 1.9.6 https://www.klubexile.com/files/file/2390-xbody-female/

The XBody Version 1.9.6 file contains:
!!VX.KlubExile.XBody.Default
!!VX.KlubExile.XBody.FemaleBodyV2
!!VX.KlubExile.XBody.Sliders

These files are placed in the Addons folder.

I also included these extra bodies.

!!VX.KlubExile.XBody.MCThicc_BBB
!!VX.KlubExile.XBody.MCThicc_CxB
!!VX.KlubExile.XBody.MCThicc_DefaultB

Once the customizer windows is brought up, select tattoos and the XBody sliders will appear in the lower part of the menu. I've played around with this and produced some good, bad and ugly models. I have noticed the game loading time has increased since installing Xbody. I may cull some of the extra bodies that do not interest me and see if this speeds up the load time.
