Great info! Thanks. I have added this to the bone and collision sections, I did reword the shared values into positive versions of their assertions. Might be worth checking that I did not break the logic.

Could try giving your bones more mass and inertia, jittery physics could be all sorts of things. - Very narrow constraints could cause undesirable 'fighting' with the physics - Your particular computer hardware might be have issues resolving the simulation (maybe test on another computer or a friends if possible) - Collisions constantly firing (turn off collisions if you have them and see what you get) - Set restitution to 0 To name a few, it would probably be easier to narrow potential issues with examples of the xml and observed issue.

Nothing of interest in the Papyrus log, though that's to be expected as SMP does not run via Papyrus. There may be more interesting logs in MyGames/Skyrim/SKSE/hdtSMP.log (not sure if that is the right name for LE but it will be something like that) If you use an editor like VSCode or Atom you can open the entire MyGames/Skyrim folder as a workspace and do a global search for various "error like" terms. You do not need to edit any mesh in 3D software, that would not solve your crashing issues. Possibly useful links around exception 0xc0000005: https://www.reddit.com/r/skyrimmods/comments/ob11qg/crashing_error_0xc0000005_memory_at_0x20_could/ (this is for special edition but it might be the same issue, has some promise as pagefile issues might cause crashing with SMP) https://forums.tomshardware.com/threads/games-and-applications-ctd-with-error-code-0xc0000005-memory-access-violation.2570897/

easy hawt comes with SMP dll's as well. I would recommend testing SMP on a fresh instance of Skyrim so that you can narrow the problem easier (which is why I recommed Mod Organizer as it makes doing that super easy). Check the log files from SKSE & SMP, they will most likely be located in ~/Documents/My Games/Skyrim/SKSE. You are looking for terms like "Error", "Exception" or "Fatal". For a setup recommendation I would have to go with switch to Special Edition... if you absolutely must stay on LE then I suppose you could search for CPU + GPU combos that support OpenCL 2.0 (probably AMD GPU + Intel CPU) Possibly useful links: https://streamhpc.com/blog/2015-02-10/overview-of-opencl-2-0-support-samples-blogs-and-drivers/

The easiest way to get SMP for Legenday Edition is by installing BHUNP https://www.nexusmods.com/skyrim/mods/100306, while this is a body mod it will give you the necessary dll files for SMP to work on other things like jewelry, capes, clothing etc. If you want to use a different body then you could install BHUNP first and your desired body mod second, overwriting the files from BHNUP. You could manually install the SMP dll's from BHUNP but I would not recommend that unless you are familiar with the FOMOD format. Skyrim LE is pretty much 'unsupported' for using SMP, if installing BHUNP does not work then your hardware (Graphics card + CPU) is most likely incompatible with the LE version of SMP. Note: You only need to install the body mod to get SMP, there is no need to do any of the bodyslide building unless you want to or you want SMP to apply to the body.

@SpartanXZero Great questions, also the guide appears to be contradicting itself there about the damping values being 0-1 or anything, I'll have to open up the various dusty tomes and look into those again. From what I recall several of these values are parts of equations, so they are relative to other defined values like mass & intertia. Most of the 'valid' values I have listed were lifted from either the bullet documentation or from reading through the SMP source code, this is somewhat flawed as the code might accept any value but in reality not any value makes sense as you have no doubt discovered. That being said I would recommend browsing the bullet documentation as it can have some helpful insights even if you have to mind map them from bullet to SMP concepts. I would be super keen to be proven wrong about any of these values, I'll try to find some time to investigate what some of the formulas behind these values are so that I can suggest some values to use.

@BentSpoon01 Apologies for not getting back to you, I was intending to play around a bit in a test environment to see if I could prove my 'fake constraint collision' theory but did not get the time to do so, funnily enough the idea for using constraints came from playing around with that very succubus tail. Sounds like you have already covered what I was going to try though, the balance of inertia vs mass vs damping is rather fiddly. I'll try to get some time to look at the problem tails when/if you release them and see if I can magic out some settings that look alright.

There is almost certainly going to need to be weight mapping involved in any proxy object creation, though I suppose you could potentially duplicate the current tails and just scale them. If I recall angular values are in radians, so 180deg would be PI or ~3.14, you most likely want to be working with values more like 5-25deg of movement so somewhere between 0-0.5. Using constraints would depend on the type of movement you are going for, my thought was to have quite small limits so that you get some sway but the tail remains mostly within a few degrees +/- of its original position. Jittering sounds like constraints fighting with something else, do you have an example of your settings for your constraints & bones?

N7R had some success with collision in this thread earlier, though I am not sure it is really the problem with yours. https://forums.nexusmods.com/index.php?/topic/3800385-a-guide-to-hdt-smp-usersmodders/page-20&do=findComment&comment=86734338 The tails are quite close to each other, presumably you have already tried various margin & penetration values? It is possible that you might have more success using proxy style objects that collide with each other rather than trying to use the actual tail mesh, the proxies could be made a lot slimmer to avoid having them clipping each other and constantly causing collision events, would probably be more performance friendly as well. You could also look into tweaking the rotation/translation constraints of each string of tail bones to sell the illusion of collision without actually using the collision system.

Hmm, not a lot to go on unfortunately. Logs seem to be mostly fine other than error 5 from smp, though to uncover what error 5 is meant to be will probably end up in a stroll through the source code for SKSE. If you have had SMP working before and it has stopped working recently then the most likely suspects would be other '.dll' based mods that could potentially be conflicting with smp loading. If you are not already using mod organizer I would highly recommend it as it makes tracking down specific mod problems pretty easy.

Alrighty, reinstalled LE with a fresh test environment and a new MO profile. Test setup: - SkyUI (mostly for MCM) - Live another life (for sanity) - FNIS (required by XPMSE but not really I did not generate idles in my test) - Racemenu (required by XPMSE) - Bodyslide (required to build the body) - [COCO]SMP body v5 LE standalone (I picked the UNP or body b version, shouldn't matter though) - XPMSE (bare bones install, no animation overrides selected) Critical point 1) Looks like COCO has you covered for the decimal notation issue, the installer for the body asks you if you are european, answer no to this and you will get dot notation rather than comma. Critical point 2) Make sure to build the entire group in bodyslide for your chosen body type, e.g. in my install I chose to use UNP3BBB so I have to build the entire group COCOUNP3BBB this comes with several choices for what I assume to be breast size related physics (A,B,C,D,P) just pick one of these that suits you (use batch build). My basic test setup has a rather dirty looking character but physics is all working as expected, you might need to turn on the 3BBB SMP physics via the hotkey or spell provided by UNP / CBBE (check your MCM). There are several warnings in the SMP logs about missing virtual mesh, that is most likely just some left over physics definition though that is not really harming anything other than log readability.

This was fixed in the open source version of SMP for special edition, unfortunately for LE you will either need to change your OS language or open the physics XML files from the mod and convert all of the decimal notation to the appropriate version for your locale. e.g. decimal notation in my locale is . (dot) while in others it is , (comma) This should be relatively easy to achieve in any kind of text editing program via search & replace (notepad++, VSCode, Atom etc) This usually means that one of the hulls/meshes is not in the expected format (LE vs SE), though being virtual ground you can probably just ignore it in this case. These could indicate a problem with the physics XML file, it might be caused by the decimal notation issue though. Either way the numbers in brackets are line numbers, so you could try inspecting BaseShapeA.xml at lines 377 & 391 to see if anything obvious is wrong. (use an editor with line numbers functionality to save yourself a headache) It might also indicate an issue with the skeleton in use, are you using XPMSE ?

@N7R Nice work, its great to have some more specific information about use cases like this

Hmm without having the actual files to do some debugging with I am not sure I can help any further, everything looks fine. My only suggestions would be to use ridiculous values in your xml to try and prove that the collisions are working at all, like using a massive margin, you could also try removing unused strings on your mesh, that has sometimes caused issues for me `Nifskope spells > optimize > remove unused strings` If you send me a PM with your xml config I can try looking for issues with it.

From what I recall (it has been a long time since I did any work with SMP), if you have a collision object set (per-triangle or per-vertex) then you should be good to go. <per-triangle-shape name="VirtualCBBE"> ... </per-triangle-shape> One of these days I'll dig into the source code now that it is available and find out how the xml is actually parsed, I do recall having issues sometimes getting body collisions working. I guess the nuclear option would be to rename your proxy collision mesh to something else to see if there is some sort of naming conflict happening, I would also usually apply some debug texture to the proxy objects to make sure they were not flying off in space somewhere unexpected.

@Musjes Are you willing to send me what you have so far? I can try having a play with it. If you believe that this is a bug with the SMP engine then the best thing to do is raise an issue on the github repository (assuming you are using the SSE version), I don't really know how much time the author has to look into bugs though. https://github.com/HydrogensaysHDT/hdt-skyrimse-mods/issues https://github.com/aers/hdtSMP64 (author has issues disabled :shrug:) https://www.nexusmods.com/skyrimspecialedition/mods/30872?tab=bugs (nexus bug tracker)

Hmm, seems like your card supports OpenCL. In theory it should work, have you tried running a mod environment with just BHUNP or CBBE to see if it is conflicting mods or something like that? Could also check out the logs to see if there is anything interesting.

Which version of the game are you running?What Ryzen CPU are you using?What GPU are you using?Seems like AMD recently stopped supporting OpenCL on CPU's https://community.amd.com/thread/231410, so you might be out of luck if your GPU does not support OpenCL.

If you are playing on special edition you can use either BHUNP or CBBE, they both have SMP support. If you are playing on legendary edition then I would just use BHUNP and save yourself the headache of getting everything together for CBBE, though you could install BHUNP for the physics framework files and plug in CBBE manually. SMP-PE path from what I recall is an attempt to get both SMP and the older PE physics systems to worth together (I could be wrong here, I never personally used it), the contents of the file seem to just be the SMP framework files for legendary edition. To manually install it would indeed just be a drag 'n' drop into your data folder.

https://www.nexusmods.com/skyrim/mods/100306 You could try BHUNP, it's been a long time since I played with LE but if I recall most clothing that works with PE should be "relatively" simple to get working with SMP instead, assuming of course that said clothing does not have custom bones for various wiggling things. I don't know of a way to get both systems to work on the same mesh and you probably would not want that anyway especially if your computer is on the lower powered end. Depending on what you want to do with each system you might be able to get them to work in tandem by making sure that SMP does not apply itself to anything that PE is trying to control, you can add or remove entries from the defaultBBPs.xml to gain some control there. There is a guide on converting PE outfits to SMP for LE. Caution, the site linked here contains sexual content explore at your own risk. (this specific post is pretty tame though)

https://www.nexusmods.com/skyrim/mods/100306 BHUNP looks like it has the option of running SMP specifically for the player and CBPC for others. Though I guess it really depends on what you want PE for.

I would recommend picking up a tool called Mod Organizer, a profile in that tool lets you create multiple instances of your Skyrim with different mods. So you can keep your current setup but create an entirely new one for testing, or if you just feel like using different mod setups for different occasions. https://github.com/ModOrganizer2/modorganizer/releases If combat gameplay overhaul is using its own skeleton then it could indeed be what is breaking things, you could try installing XPMSE last (or reinstalling it depending on what tool you are using to manage mods).

Sorry friend, I don't think there is much we can do to assist there. I would suggest contacting whoever made the patch as they are more likely to know about potential conflicts with other mods. You appear to have narrowed the list of culprits well, nice work! I would not really expect Combat Gameplay Overhaul to cause issues for SMP as it does not have any `.dll` files that I can see, usually those libraries are what conflict with SMP's engine. Some things to try: * Remove Combat Gameplay Overhaul to test if your SMP starts working again (this will give further evidence that it is the culprit) * Make a mod profile with only the required files to make the PE + SMP + Combat Gameplay Overhaul work and see if SMP is still broken (this will also help confirm that CGO is the issue) * Take a look at the SMP log files for any clues to what might be going on. (C:\Users\<user name>\Documents\My Games\Skyrim\SKSE - If you are on windows, not sure about linux) * Talk to the author of Combat Gameplay Overhaul and see if they know of any reason that the mods would conflict * Talk to the author of the PE + SMP patch to see if they know of reasons that the two mods would conflict Usually I would recommend not trying to mix PE and SMP, if you can live with alternatives try to just use one or the other.

I have intentionally not lingered on rigging. Rigging as a subject is somewhat dependent on the software you choose to use, though the fundamentals are transferable, it should be rather easy to find tutorials on it from whatever your favorite learning source is. Rigging for Skyrim specifically I can not really vouch for as I have been out of the 'game' so to speak for a long time. The nexus wiki seems pretty legit from a brief glance. http://wiki.tesnexus.com/index.php/Creating_an_armour_for_Skyrim._Part_1 https://wiki.nexusmods.com/index.php/Category:Tutorials This guide/document is just an investigation of SMP itself, it would be great to have someone make an end to end workflow guide for actual use cases though. Your best bet for up to date information like that is probably the discord servers of some of the active SMP outfit creators.

Interesting, I have not personally tried to get character hair working so I can not be of much use there sorry. I would have thought SMP would be applicable to anything as long as the mesh is actually present in the game, though it is possible that some kind of merging or renaming goes on behind the scenes with character mesh/hair. Someone with more experience in body mods / hair mods would be good to reach out to for some insight there, I would certainly be interested in learning more about how that works behind the scenes.
