Note: I am not actively involved with Skyrim and its modding community right now and am busy with many other things which is why I haven't replied to all the questions posted in this thread. Hopefully other people have been helping those who need it. Eventually I'll get back into Skyrim and be able to help out more here, but as for right now I'm inactive. also, 100k+ views. <33 A) Intro/ Contents: Intro: When I first decided to get into HDT, I'll just say it was kind of a frustrating mess due to complete lack of a detailed tutorial and information on it. I spent too many hours going through error after error and figuring things out that could of been solved in 10 minutes through a very detailed tutorial. So that's why I've put this together! Do note that everything here might not be entirely accurate as I haven't been using HDT for that long, but I'm just going to say what worked for me personally and make this the kind of tutorial I would of liked to find when I was first installing it all. A lot of the things in this guide I figured out purely from trial and error and searching around. You may have seen some other tutorials.. and while they're usually accurate they're also very simple. I have nothing against those tutorials and the people who wrote them. However this tutorial is intended to be very in depth and just be freaking huge and extremely descriptive to make sure you can understand everything. This doesn't mean HDT is very difficult or complex to install, but it is common to run into errors so hopefully I can help you get by most of them. If you'd like to view some other tutorials check out Monsto's post. Eventually I may include a tutorials section in this thread as well. This is targeted for ultra-newbies so will be very descriptive and possibly insult your common sense at times. If you want something simpler then just look around the forum Also, important note. Mod Organizer seems to have problems with certain things not working correctly when it comes to HDT. If you're getting issues, you may want to install certain things with Nexus Mod Manager instead or manually. If I know for sure installing through it can cause a problem then I'll specify in that section of the tutorial. Contents: Post 1: A) Intro/ Contents/ THIS HDT Guide C) F.A.Q. D) Downloads E) Additional Downloads Post 2: F) CBBE for HDT Guide G) Clothing for CBBE w/ HDT Post 3: H) Installing everything through NMM I) Collision (Havok Object) And that's all of it for now. So without further ado, let's get started. HDT Guide: .5. (Optional Step) Pre-req for XP32. If you're going to install the recommended skeleton then first install this: Realistic Ragdolls and Force You can also get this if you want more sliders in-game: Enhanced Character Edit (has some compatibility issues with Race Menu) Not at all required, but I'm mentioning it due to the modified XP32 skeleton having an option to extend it. 1. Install a skeleton. Quick note: You don't actually have to follow the rest of these steps in this specific order. Some people prefer to install the skeleton last and let it overwrite anything else. Do whatever you're comfortable with. The commonly recommended one is XP32 Maximum Skeleton Extended. If you use Nexus Mod Manager/ NMM then I highly recommend installing it through there. It has an actual installer and whatnot to go through that'll come up. (If you don't know how to do this then check the mini-guide for manual-to-NMM installs down below) Make sure to select the right options - that you use HDT and whatnot. If you use ECE then the extra ECE sliders are a great addition and very useful for not only customizing your character, but moving items around to avoid clipping. It is possible that these extra sliders can mess with certain body types in ways you don't want. As of now, the only one I know of that is effected is the HDT body for CBBE. If you're going to use it then avoid the extra sliders. They work fine with the AdvancedTPPB body for CBBE though. For any other body types, you'll have to find out on your own. Make sure to overwrite anything from the ragdolls mod with this skele too. There's also a file called "skeleton_female.hkx" that some have suggested to delete while others say to keep it. Its in: data/meshes/actors/character/character assets female Keep it in there. One final note on the skeleton is that you should avoid installing anything over it. For example, if an animation pack wants to overwrite parts of it then don't let it. And if you install it last, make sure to overwrite everything with it. 2. Install a body. Depending on your wants, the body as well as the type may vary. For full normal physic movement as well as breasts and behind bounce you'll want a body with TPPB. I use CBBE so I can give a detailed guide for anyone else who uses this body type. It'll be down below. For other body types, I'm not sure - just select the TPPB variants. I tried Sevenbase out once and picked TPPB through the installer and everything seemed to work fine. There's also an HDT Sevenbase body, but I'm not sure what all it is or does. If you do use CBBE then check the second post for a guide. 3. Install HDT. Here are a few versions: v10-24-stable v12-29 v14.28-latest When I first installed HDT, I used v12-29 and did have some issues but they may of been caused by something completely different. Nonetheless, 10-24 and 14.28 have worked fine for me. You might want to just use the most recent. Up to you. Download these files and put them into your folder which is here: Skyrim/ Data/ SKSE/ Plugins You can install them through NMM if you prefer - check the guide below for that if you don't know how to. It'll come with the default XML. XML files heavily change how things move around and once you get everything working then I recommend trying lots of them out or editing them yourself in a program called Just For Fun until you're satisfied. 4. (Optional) Optimize Havok. Go to: User/ My Documents/ My Games/ Skyrim Open up the Skyrim.ini file. Notepad works fine to edit it. Now at the bottom, paste in: [HAVOK] iNumThreads=4 bHavokDebug=0 fMaxTime=0.0157 bDebugMultithreaded=0 Change the iNumThreads to the amount that matches your CPU. This may actually boost your performance for the better. If you really aren't sure and don't know how to find out your thread count, you can download Speccy and run that. Go to the CPU tab on the left side. In the middle it'll show your threads. 5. (Optional) Make an ENB edit. If you use an ENB and use version 10-24 or 12-29 of HDT then open up your ENBseries file from your Skyrim root folder. You installed the ENB so you should know how to get there Scroll down to the limiter section. It should look something like this: [LIMITER] WaitBusyRenderer=false EnableFPSLimit=false FPSLimit=60.0 Set the WaitBusyRenderer part to true. You might notice a performance hit. This isn't required on the newest version of HDT. ----- And there you go. From here you can install different HDT-related things, experiment with and/ or tweak XMLs, install animations to see how they work with HDT, just play Skyrim and stare, etc. Do note: You do not need TPPB animations like you do when using TPPB without HDT. Animations are no longer required for bouncey-bouncey. Any animations you like will work and depending on XML, they can work quite well. Check the additional downloads section for some different things. C) F.A.Q. Q. Movement works but its very jittery. wut do i do? A. Make sure to complete steps 4 and 5 and this should fix it. If it doesn't, it could just come down to your install or XML. The default XML that comes with HDT shouldn't look jittery if you did everything right. Q. Characters breasts look weird and flop around into different sizes and get stuck in certain places and all kinds of awful shit! A. I recommend uninstalling everything you installed for HDT including your character body and skeleton and starting over. Then reinstall using the things I recommended in this thread and maybe trying another version of HDT. If you did all that and are still having issues, post here and be really specific as to what you did. Q. The breasts.. look like massive torpedos. A. If you use CBBE and they're rather torpedo-ish and you want the default look then install the fix for it posted in step 3 of the CBBE guide. If you use another body type, some different things might cause it and fix it. Check out the post(s) here and here. Q. The breasts.. look like they got ran over by a truck. They're squished and/ or deformed. A. Probably a skeleton issue. Re-install the skeleton and overwrite everything with it. Q. Showracemenu sometimes breaks my character's physics. What do I do? A. Nothing to my knowledge. This sometimes just happens. Save your game and restart Skyrim completely. The changes will be there and HDT will work again. Q. My character's rear barely moves at all while everything else moves fine. A. If you're sure you have a TPPB body and skele installed then its probably just your XML file. If by barely moves, you mean you can notice it jiggle a bit when coming to a stop? Then its just the XML. Try different ones out or edit them in Just For Fun. There's also one included in the All-In-One download in the additional DLs section that should definitely work. If you want to make sure its working try that out.. but I don't really suggest it for normal use unless you like the ass to bounce like a basketball LOL. Learning to use JFF is your best bet Q. Collision with Havok Object doesn't work well for me and my character's breasts are stuck pointing upward. What did I do wrong? A. Do you have any hair with physics installed? They won't work with collision - at least from havok Object. You can either unequip the item when using this hairstyle, change to a hair without physics, or install a modified version of HDT and Havok Object that works with hair physics. Check the additional downloads section for this. If you don't use any hairs then it might be a skeleton issue. Q. My character's hair gets stretched and distorted across the screen. A. This can sometimes happen when alt-tabbing without pausing. Just reload and it should be fixed. Q. NPCs breasts spaz out and go crazy sometimes.. Uhh? A. I think this happens the most from collision or at least Havok Object in my experience. Removing Havok Object from NPCs has made their tits rest for me. Its not something that'll hurt your game.. though I'm not sure why NPCs have to have the object equipped in the first place. Should of just been player-specific. I wonder if I can edit it in the CK to be like that. It might happen without Havok Object, but if it does it shouldn't happen much. Just reload the game to fix it. I wouldn't worry much about it unless it never stops and happens to every NPC or on a set basis. Q. Things effected by HDT physics continue moving even after opening up the Steam overlay which pauses the rest of the game. Is that okay? Yes. Its just a funny side effect due to how HDT works. Nothing to worry about. Q. My game crashes when I exit it.. Should I worry about this? A. No. This is a normal side effect that a lot of people seem to have according to posts in other threads on the subject. Annoying, but not a problem. I fixed it once without knowing how but got the issue back after a reinstall. Since then, I've fixed it after downloading the DLC and updating mods for it. Not sure if its specifically related to that or I just got lucky, but I never had any issues when the game did crash on exit so I wouldn't worry. I'm not sure if its directly tied to HDT or things that go with it or a conflict. Q. My game crashes and when I try to load it back up there's a new save file named "HDTPhysicsExtension" and loading that save crashes my game again.. umm? A. These saves are created after an error. You can check your HDT log file to see what's up and if its related to HDT. It isn't always necessarily directly from HDT I don't think. I believe if you fix the issue then the save will become loadable which is a way to find out what the problem is and when its resolved. It could of been a messup with the physics and chances are it won't happen in the same spot again. If it happens extremely rarely I honestly wouldn't worry about it. If its happening frequently then you check your log file. You may have a big HDT issue on your hand or it may be something completely different. Q. Where can I get XML files? A. I suggest just looking around this forum. People have posted a lot of them. You can use JFF to tweak them too.

I'm sure plenty more exists, but a lot of downloads to things are buried deep in places. I'll add more things to the list as I or others find downloads for them, but could really use the help. If anyone finds any HDT clothes, hair, accessories, or anything of that sort then please do post here with a link to get it so I can add it to the list. Who knows what we'll see as time goes by. If you want to hunt around for more HDT stuff then you can try this place: bbs.3dmgame.com There are also things buried in larger threads that don't have their own topic. You can try around the board. One place you might find things in is: What Mod is This? If anyone finds some other HDT downloads for things then please do share them so we can expand this list. Anyways, that sums up everything for the main setup. I was going to make a credits section and might later as well as a section for other tutorials, but for now I'll just say thanks to all the people who have made this awesome stuff and thanks to Blabba and CLP2011 for helping me out when I was first installing HDT. Feel free to ask questions or post any comments. Keep in mind that I haven't been using HDT for a long time and I don't know everything about it so I may not be able to give the best answers or always know how to fix everyone's problem. Nonetheless I can try and others can always post to help those out as well.
