Installation:
Use your favorite mod manager, or manually extract the files.Have these files load after YUP (or any other bug fix that contains meshes) and before the rest of your mods.
Uninstallation:
Use your mod manager's method of uninstalling mods, or delete the meshes folder if you installed it manually and hope none of your other mods used meshes. Please use a mod manager.
Requirements:
The base game. DLC fixes are included but not required for the fixes to work.
Incompatibilities:
Minor conflicts with Tale of Two Wastelands (duplicate meshes), otherwise just make sure mesh replacers overwrite these.
Tale of Two Wastelands:
After 3. 3 I'll try to maintain an optional file that only includes meshes not included with 3. 3. Lol. Lmao even. If it gets too big I'll consider maintaining something like this.
Bug Reporting:
Use Stewie's Tweaks with "bMeshPath = 1", open the console with "~", click on the mesh, and take a screenshot, and include that in your bug report.
