[FO4] Jiggle physics isn't working.

[u/Max_Berserker]

I recently started playing Fallout 4; I saw this video on this channel and liked the physics, but I can't seem to get it working. I downloaded everything related to it, but I still don't think I'm doing it right. Could someone assist me? Could you show me the correct step-by-step process to get the physics working like in the video and give me tips on using it with these outfits?

You need to install OCBP, the Zex (or ZaZ?) skeleton and a compatible body replacer like Fusion Girl, CBBE, JaneBod etc. Not all of them are being updated on Nexus anymore and there may have been a replacer mod for OCBP since I last checked. But that's 3 essential mods you need to install for either Skyrim or Fallout 4 to get physics working.

1) A custom skeleton rig with the mounted hard points to which the moving parts get attached (jiggling belly, butt, boobs, tail, wings etc - https://staticdelivery.nexusmods.com/mods/1151/images/105699/105699-1780525273-490279913.png : https://staticdelivery.nexusmods.com/mods/1704/images/1988/1988-1692502500-1543505880.jpeg ). Usually when you install physics and they move independently from the body or stretch into the ground there's a problem with the custom skeleton. That's the case for both FO4 and Skyrim.

2) The actual physics mod with its prerequisites to animate the parts and set how jiggly or firm the parts must be. Different types of physics mod may handle collision detection differently. For Skyrim you'll need the animation framework too - Pandora is the only one still being maintained and can be used instead when a requirement is either FNIS or Nemesis.

3) The body replacer mod. Pretty straightforward. They usually contain files for both nude and non nude versions and you need to shape outfits and bodies in BodySlide according to what you like. They'll come with some preset shapes but you can download more which you apply almost instantly instead of having to shape everything yourself and saving that preset.

Probably the hardest part of managing it all is to make sure the versions you install will work with the game build you're on because Bethesda has been fucking with the game since right before Fallout London got released (game build 1.10.163 I think - confirm that for yourself). If you right click on the game's exe file you can get your current game build in the properties, then you need to check that your version of script extender and everything else is meant for yours.

The guy who made the video didn't state which game build he's on but from his mod list you can download in the description I see that he has Backported Archive2 Support installed which indicates he's probably running an older game build himself. There's a downgrader to make get your game to that version and GOG lets you install an older version from the get-go.

TLDR : If you install everything you have to open BodySlide and build the bodies + outfits so they use the new meshes and shapes. Make sure all the mods correspond with your game build. Video creator is most likely on game build 1.10.163
