- It's not working.
If it doesn't show up ingame make sure steam actually downloads the files after you subscribe, try restarting steam. If the textures aren't working correctly after enabling it ingame, restart your game. If these fixes don't work post in the comments or the pinned bug report thread and i'll try to help.

- It doesn't work in Multiplayer.
Body mods have no XML files and require a game restart in order to load correctly, preventing them from loading on the fly as you join a server. In order to use the body in Multiplayer each player that wants to use it must have the body mod files loaded and active on their own game prior to joining a server. This is the only way to load the bodies and then they will work as expected when joining a multiplayer server.

- How do I change the load order
In B42 the button is at the bottom right by the Accept button. In B41 you'll need a mod like Mod Manager and the same function will be there.

- There's a ring of yellow skin around the neck of my character / some parts of my character are pale but others are not
Another skin texture is likely overriding the base body texture and peeking through any gaps that are not covered by textures introduced by Spongie's customiser. This is likely a load order issue of a body texture loaded from another mod being lower in the order than Tomb's Player Body + Goth Skin mods. Putting all the body mods at the very bottom of your load order will fix it, and won't affect anything else.

- How do I get X,Y,Z look from the mod screenshots?
All of the looks showcased in the ingame screenshots are attainable combinations when using combinations of vanilla clothes and the clothes from the mods listed in the description. The first image contains clothing from an upcoming mod, stay tuned for that release!

- Does the pale skin include the Muscle + Face textures for the Customiser?
Yes. Be sure that it's loaded after the [Customisation] mod of Tomb's Player Body to ensure that the files from this mod take priority.
