What does this mod do? It adds wearable Underwear to the Wasteland; this underwear can be worn underneath any armor or clothing.
The base barter value of the underwear can be customized through the in-game mod menu, as well as whether NPCs will be given any underwear, whether the mod should affect males, females or both, and whether the player should use an underwear mesh different from the NPCs' one.
This mod is based on Undies Underneath from popcorn71 for Oblivion, and is thus named accordingly.
I installed it, but nothing happened... The mod starts out with every option disabled; you must enable them through the in-game mod menu or the mod won't actually do anything.
Do I need any DLC or any other mod? Requires FOSE and at least one nude body replacer... personally, i use Breezes FO3 Males and DIMONIZED TYPE3 female body.
DLCs are not required.
I don't really like the included default meshes... can I change them? Sure! If you want a different mesh for females, rename the .nif file that you want to "femaleupperbody.nif" and place it in Data\Meshes\UUndies\f If you want a different mesh for males, rename the .nif file that you want to "upperbodymale-underwear.nif" and place it in Data\Meshes\UUndies\m
What should I do to get a different underwear mesh for my character? If you want the player to use a unique underwear mesh: if female rename the .nif file that you want to "female.nif" and place it in Data\Meshes\UUndies\player if male rename the .nif file that you want to "male.nif" and place it in Data\Meshes\UUndies\player
Then, activate it using the in-game menu.
I changed the mesh files, but Where should I put their texture files? The path where texture files should be put is defined by the mesh file; generally, leaving the texture file where it would normally be (as after installing the mod it's included into or following its author instructions) should do the trick.
Is there any mod incompatibility? This mod is not compatible with Children of the Wasteland nor children in general; if a child happens to
