BodySlide Mod and Outfit Studio | Fallout 4

A: Read the mod description, especially the FAQ. Read the stickies. Reinstall BodySlide. Install BodySlide manually if your mod manager of choice fails to do its main purpose.

A: You might have to set Fallout 4 BodySlide Mod (and tools that launch BodySlide such as NMM and MO) to always run as an admin.

A: Make sure you have added the line “bInvalidateOlderFiles=1” to your “Fallout4Custom.ini” file in the “Documents\My Games\Fallout4” folder.
Check if your player character or NPC is using a custom race, or your outfit a plugin that points to a different meshes folder (unique player mods).
If so, you will have to manually move the built files to the correct directories for the race/NPC.
Make sure your character has its weight at the very centre of the weight triangle if you want the body to match what you see in the preview window.
Take a look at the “last modified” date of the files you built and check if it changed (see Q2).
You’re using Windows 10 and recently installed an anniversary update. For some reason, it can cause permissions issues for some users even when you are admin/the only user of the computer. There is nothing we can do to help you here, you will have to figure it out yourself.

A: You need to install addons for Fallout 4 BodySlide Mod, such as the CBBE body or various other mods that support BodySlide.
If you’re using NMM/Vortex/MO, make sure that you’ve correctly linked the Fallout 4 BodySlide Mod directory/executable to the program and are running it through them properly. See the installation part of the description!

A: Registry isn’t set, or Fallout 4 BodySlide Mod wasn’t installed properly.
Launch Fallout 4 using the Steam launcher instead of F4SE to fix the registry, and try launching Fallout 4 BodySlide Mod again.
If it still doesn’t work, make sure all the files are installed correctly and you’re running it as admin. If you have to set the directory manually, ensure it’s pointing to Fallout 4/Data.
Try downloading and installing the mod with all anti-virus software disabled.
Note that Vortex/MO aren’t perfect and may not install all of the files, especially Setup.xrc. If so, you may have to install manually.

A: You need to install it correctly, according to the instructions. You need the outfit and body textures installed in your Data directory. You also need to launch Fallout 4 from the default/Steam launcher (not F4SE) to sort out the registry, or manually set the directory to point to Fallout 4/Data through the ‘Settings‘ button. Only then BS/OS will be able to find and load the textures.

A: Fallout 4’s meshes are saved using 16-bit half-precision positional values. What this means is, for meshes that are very small but at the same time have many polygons, there can be a lot of distortion because it’s not precise enough.
The full precision checkbox in the shape properties of FO4Outfit Studio makes the shape it has been activated for save with the full 32-bit single-precision positional values that previous games had, so there will be no distortion. This should only be used when you really need it, though.

A: For in-game morphing to function, your bodies and outfits need to have so called TRI morph files built for them.
CBBE and its vanilla outfits already come with pre-built and attached morph files, so you can use it out of the box.
If you are customizing the body or any custom outfits using Fallout 4 BodySlide Mod, then you have to check the “Build Morphs” checkbox before building.
Only then the built set can be morphed in-game using LooksMenu or other script mods. For LooksMenu, you need the slider definition JSON file coming with CBBE (or potentially other body mods).

A: You have to split all edges of your mesh along the UV seams. The NIF format only supports one texture coordinate per vertex, so UV seams need duplicated vertices.

A: This means the driver of the graphics chip used doesn’t support the version of OpenGL that’s required. Make sure to update all of your graphics drivers (manually). In case there are multiple graphics chips built into your PC, set Fallout 4 BodySlide Mod to run with the dedicated one only.

A: No. If you don’t save a preset, then it’s gone. Your only option is to try and recreate it.

A: You need to make sure the body you have installed is actually Fallout 4 BodySlide Mod-compatible, and you need to follow the installation instructions. With Vortex, you need to run BodySlide/Outfit Studio from your actual game folder. With MO, please contact the MO devs/read their own documentation.
