Step by Step setup basics for HDT Physics Extension
It is required!
Install a body with BBP or TBBP compatibility.
Start here if you need one. Well known bodies and their derivatives will have this. Others will say in their documentation.
Install skeleton with BBP or TBBP compatibility.
Start here if you need one. Most often, this will be an xp32 created skeleton. Others will say in their documentation.
Download the HDT plugin for SKSE.
Start here if you need it. Also available from the HDT Download link in the menu bar at the top of the page.
Install with a mod manager or open the zip into the Skyrim game directory.
If you're using a version older than v12-29:
Enjoy the show.
This will get it working first. You can THEN install add-ons afterwards.
See the 2nd post in this thread for load order information and examples.
If you have problems specific to basic installation, start a new thread in this forum. No need to pile all the questions into a single thread anymore. You could reply to this thread, but a new post will get better response.
FNIS is not required
HDT is not an animation.
About the file Skyrim/data/meshes/actors/character/character asssets female/skeleton_female.hkx
- If you leave this file intact, it will allow every animation to have HDT Physics attached to them. The animations provide mesh movement for HDT Physics to seed from.
- If you delete this file, BBP/TBBP animations will not run. It will allow HDT Physics effects by themselves.
They are different effects, neither entirely bad.
No breast movement
make sure that you have put hdtPhysicsExtensionsDefaultBBP.xml in the /data/skse/plugins along side the plugin dll. Reread the Step By Step above.
Crash to desktop?
You must have a TBBP compatible skeleton. Without it, you will ctd, usually when disrobing, perhaps at other times depending on your install. Reread the Step By Step above.
Crash to desktop and have RaceMenu installed?
Make sure you are using RaceMenu v2.15 or newer. Older versions of nioverride.dll will cause HDT to crash randomly.
Please gather as much detail as possible and make a new post in the forum.
Nuke the site from orbit. It's the only way to be sure.
This is my advice if you are having a consistent and fairly predictable problem of any sort. It's a pain in the ass and time consuming, but in the long run it is the easiest way to solve major problems.
People try very hard to keep their install intact and in the process wind up taking WAAYY longer than if they had just nuked from the beginning. Save yourself hours of frustration and just go thru the pain in the ass of starting from from scratch. Note: You don't have to destroy your current install. Rename or backup your skyrim dir, then reinstall the game and the mods from scratch. Use Mod Organizer (much better than NMM), install the very basics body mods + HDT, make sure it all works, and then build up from there. Your save games will remain untouched if you do this like I describe by moving the old out of the way and downloading new.
HDT Physics Extension is a high order (system wise), high demand mod that does things typically reserved for low order (not driver level, but pretty low) software. It's like if you were to open a BurgerShop inside an existing McDonalds using all their stuff to sell your burgers. It basically puts the game engine up on blocks (like a car that's about to get worked on), adds a highly complex feature that the game was never intended to have, and then tries to let everyone go on their merry way. It has succeeded in every case except the few that are caused by mods that do something nonstandard.
