Arrok's SexLab Animations & Resource for Modders  

Tools needed:
3ds max 2011 
Havok's 3ds max exporter http://www.havok.com/try-havok (Its free but you have to fill out some info)
Niftools 3dsmax plugin (Build created by figment) !Very important plugin! http://www.skyrimnex...ile.php?id=5622 or here: http://niftools.sour... plugin#p21708 
Fallout mod manager or a BSA extract tool to extract the files out of the BSA files: http://www.fallout3n...file.php?id=640 (The BSA browser is awesome and you can install this without having fallout installed just pick fallout 3 when you open the browser and browse to skyrim)
Hkxcmd tool for extracting animations from the game files (not for importing yet).
Skeleton Text file for havok (Included in this file)
3ds max Bone rig (included in this file) (A giant thank you goes out to SaidenStorm from the bethesda forums for helping me with the missing bone parameters in my 3dsmax file!!)
 
(this is from Cherry Hotlings description page on nexus for CHSBHC,...which is where she is refering you where the bones list is.

Xp2's Tutorial (for learning what to check and not check when importing .nifs) (The hkxcmd stuff isnt that important,...as it only works on animations created with teh vanilla skeleton)
https://aqxaromods.com/skyrim/animationsk/6272-animation-tutorial-for-3dsmax.html
 
I know they say get 3ds max 2012,....but get 2011...
 
2011 is the lastest release that still supports havok content tools 2010.2 (2010.2 is the only version compatible with skyrim must be that version)
 
Xp2's tutorial is good for letting you know which setting to import with, and has links to the best videos to learn the basics of animation.

And here is Cherry Hotlings tutorial on getting BBP to export correctly,..you're also gonna need to download her mod on nexus for the animation rig, bone list .txt file, and her CHSBHC skeleton.
 
Steps: (assuming you installed all the tools above)
1) Open the fallout mod manager BSA Browser --> select fallout 3 fromt he popup --> Click the open button --> browse to Program Files\The Elder Scrolls V Skyrim\Data (Or wherever your Skyrim install is) --> click on the Animations.bsa --> click open
2) On the left pane click the + next to skyrim --> + Meshes --> + actors --> + character --> + animations --> Click on female
3) on the right pane click on the animation you want or Highlight a bunch of them and then click extract (dont click extract all) select a folder you want to extract to (I suggest you make a new one on your C: root drive if you havent already, it will make the next step easier(Steps below on what folders to make) ((Im using mt_idle.hkx as my example))) then click ok.
3a) For the steps above I recommend making a few NEW directories on your C: drive. Make the following:
C:\Skyrim , and C:\Skyrim\data . 
-Put the animation.hkx you extracted above into the C:\Skyrim\data folder.
-Put the Skeleton.hkx file that comes with my mod into the C:\Skyrim\data folder 
-Put the hkxcmd.exe tool in the C:\Skyrim folder.
4) Open a command window in windows 7 type cmd then enter in the start bar, other windows version then its: start --> run --> type in cmd then enter
5) in the command window type “cd ..” (without the quotes and keep typing “cd ..” until you get to just the C:\ prompt. 
6) Now type “cd Skyrim” (again without the quotes) you should now be in the C:\Skyrim directory that you copied the hkxcmd.exe into.
7) Now type(WITH the quotes this time): hkxcmd ExportKF "c:\Skyrim\Data\Skeleton.hkx" "c:\Skyrim\Data" "c:\Skyrim\Data-out"
7a) Ignore the warning message about bones not found, its why we did the step above, it creates the missing bones for you. Fancy huh?
8) This will create a new folder: C:\Skyrim\Data-out , You will find the animations you extracted to the C:\Skyrim\data (In step 3) now exported in the .kf format in the C:\Skyrim\Data-out directory which you can import into 3ds max.
9) Open 3Ds Max 2011 and open the 3dsmax bones file that was included with this package ("CHSBHC-Vx.x-Physics-Bone-T-Pose.max"). (Once loaded you should see a bunch of bones standing there staring at you ...... waiting)
9a) (Optional) You can import the mesh I modded that comes with this file so you can see whats going on with the animation. Click The 3ds max icon top left --> import --> Browse to the femalebody_1.nif (if you want to use that body shape) --> click ok --> UNCHECK cameras and UNCHECK import skeleton(Very important those 2 are unchecked) leave everything else thats already checked --> click import (The body should be imported and using the bones, yay!)
10) Import the new animation into 3ds max. Click the Max icon top left --> Import --> browse to the mt_idle.kf --> click import on the popup (Leave everything checked)
11) Animate! whooo hooo im animating, im animating! Dont forget the new Left Breast, Right Breast, Left Butt, and Right Butt bones! Move them around for whacky fun!
12) Now its time to export our animation with the havok plugin for 3dsmax (The save file has all the filter settings built in so no fretting!) Click the Disk icon on the Laft top of your screen (If you hover over it, it says export its left of the viewport name and near the Graphite modelling tools text or about an inch strait down from the 3ds max top left button)
13) In the Havok popup window under the Configuration set section click the dropdown and select Animations (if it isnt already selected)
14) click on the Create Skeletons text, this will populate the right pane with info. under where it says Build rigg on the right pane, make sure "from file is checked and "use file order" is checked. --> click on the ... next to the "From File" section and browse to my "CHSBHC bone Rig Breasts and Butt.txt" file that was included with this file.
15) click the Create Animations text in the Configuration section of the Havok popup --> on the right pane make sure "From File" is checked --> click the ... next to the "From File" area and select my "CHSBHC bone Rig Breasts and Butt.txt" again.
16) Click on the Write To Platform text under the Configuration section of the Havok window popup --> on the right pane under "Filename" click the ... --> Specify a new location and filename for your animation (in my case I used mt_idle.hkx !!VEry important you select a location to save in this step or you will get an error that it cannot save it!!)
17) Put your new shiney and polished animation in your "The Elder Scrolls V Skyrim\Data\meshes\actors\character\animations\female" (If it’s a female animation) folder and load the game!
 
Viola! your done!
Once you have done this the first time you only really have to do steps 10 - 17 from here on out to create your animations!

Here is my own quick tutorial on 2 actor animation (please make sure you can at least replace the game's default mt_idle using havok content tools and a BBP skeleton before attempting this)

I use the CHSBHC skeleton for male and female.
 
So yes exactly, just import the male meshes over it.
 
You can get her animation rig scene max file from her nexus page for max 2011.  I just start with that rig. I have one saved with male meshes called "male templet" and one saved loaded with female meshes called "female templet"
 
With those 2 separate scenes,...heres how you combine them to animate, then separate to export...

To edit 2 actors...
 
First just make a male t-pose at origin scene (import and freeze meshes too), save and close
 
Then make a female t-pose at origin scene (and import and freeze meshes)
 
Click the green 3dsmax logo /file menu button at the top left corner (the one to open, new scene, reset ect.)
near the bottom of the list you see the references option, click that, and select xref scene. 
 
click "add" at the top of the box. Select your male t-pose scene you created and it should pop up. Keep the Xref window open and look at the "add" button again and gaze downwards until you see the merge button. Press the merge button.
 
Now you can animate them both in the scene.
 
The males bones are on the bone list under the female's.  Its easy to tell b/c they are separated by the meshes.
 
When its time to export your animation you'll have to split the scene to make 2 animations. Its easy though.
 
Make sure your scene is saved with both actors, then highlight every bone on the bone list under the last female mesh (starting at the first male mesh) press ok and hit your delete key.
 
The male will disappear and you can export your female.
 
Open the scene with both actors again, and highlight the female bones and meshes this time and hit delete. Now you export your male.
 
Thats how I do it.
 
The male and female t-pose scenes I refer to here in this quote of myself is the templets I have described above.
 
Reason for the Xref, and not just straight up import another scene is b/c importing tries to rename the bones (since they have the same name)
 
But merging allows duplicate bone names for some reason. 
 
Now about the positioning,...just make sure you keep them around the origin. Also keep them oriented along an axis if you want to keep your rotations from becoming very complicated.
 
Once you're fully done animating, you'll need to test the animations in whatever mod you're animating for.  They are all different,..(as far as positioning goes)
 
You may boot up skyrim to find that your animation has both actors too far apart and one rotated 180 degrees in the wrong direction. So you're gonna need to get back in max and focus on one actor (I focus on female) and keep adjusting her and booting up skyrim to test the alignment.
 
If you're making SexiS replacers,...I know the values you have to move your actors once you finish animating,....I have looked at its scripts and noted the distance they displace the actors,...which is what throws off the animations.
 
Heres my explanation of IK Solvers (this is how you contrain bones from moving when you move their parent bones (in the bones list selecting the display option "show children" really helps here)
 
IK Chains: 
 
First choose the bone your chain will start on.
 
At the top of the MAX screen you see the animations tab,...once you click that you see a IK solver option,....mouse over that and you see the HI option,...thats all you'll be using for this.
 
Once you select the HI option the program will be waiting for you to select the bone that you want to start an IK chain with. Keep in mind you can press the H key to bring up the bones list and choose that way,...you dont have to click the actual bone with the mouse.
 
I highly recommend you only start IK chains with either thigh L or R or either upperarm L or R bones
 
Once you select one of those bones,...the program is now waiting for you to select the bone that will complete the IK chain.
 
If you started with R thigh,...then end with R foot......same for L thigh
 
If you started with R upperarm, then end with R hand, same for L
 
This will, for the most part,...will constrain your arms and legs from moving much at all when you move parent bones,...or bone connected to parent bones.
 
However, your feet and hands will still pivot oddly,....soo
 
Start an IK chain on foot and end with toe to keep feet planted   Start a chain on hand and end with animobject to plant hands.
 
You will notice that a bunch of small axis markers appear all over your actors,...these are your IK chains, and they show up in the bones list. (it would help greatly to have your bones list "show child" option enabled". Do this at the top of the list you see some tabs, one has this option.)
 
You are free to animate IK chains with autokey. Also, you are free to use the position tool to do so (cant rotate them). Using the position tool will not destroy your mesh when you're using it on a IK chain,.. b/c the chain stops the mesh from streching
 
I strongly recommend only using IK chains on the bones I list above at first,....once you get used to it (and you will fast, its not hard to see what it does) then you can experiment with your own chains.
 
In order to move your actor properly (for offseting) when you have IK chains,... you must select all of an actors chains along with the NPC com to displace the actor as-is.
 
Btw if you didnt know, and were curious IK stands for "Inverse Kinematics" which is just a physics term meaning loosely "opposite motion". And thats what its doing,...its using kinematics equations to calculate your opposite motion to keep a bone from moving too far off a positioned state.
Or "contrain" it.

Have you tried this tutorial (http://www.youtube.com/embed/ozSNKHeop6Q) to do the bounce?

New Replacer (not in extension mod)

BBP Reverse Cowgirl (On Back Replacer).rar

Check out the intro stage,...switch positions back an forth if you must to get it right

I'm not gonna update the .esp everytime I make a new animation set b/c its a lot of work for such a small addition, so while I'm waiting for enough to update, ill post them here as I finish them so you can try them as they are created.

They are also gonna be mostly "On Back" replacers because that position is easy to replace. So unless I have more than one animation waiting to be added to the mod, it will always be an "On Back" replacer.

New Non-replacer mod:

Just finished working on a Non-replacer animation extension mod for SexiS, the framework provided by Redneck2x, so thanks. I will now be shifting my focus over to adding animations to this plugin, and have no intentions to continue making replacers. I'll be leaving up the old ones, but all new animations will be as an update to this mod.

Mod Description;

Specifically, this mod will replace 3 of the original 20 SexiS animations those are,...

AP Cowgirl (with my BBP cowgirl)  

MLA Sidefuck (with my BBP Sidefuck (and yes I did align it, it was extremely hard to b/c that position doesn't obey position scripts))

Leg Up (with mithosanimation) - I did edit the SexiS behaviors to make his intro work almost everytime though. It looks nice working as intended.

EVERY thing else is now a Non-replacer,...they have their own positions, and stages numbers ect. I actually added a stage to each the Standing , and to the On back animations. Also discarded the acyclic intro on my former replacers, and now the first animation is view able indefinitely. ( Like the Boobjob )

I have tested and aligned many of my animations better than previously. The only animation not alinged (for me) is the Arrok_Sidepostion I think its animation 19.  Reason is I plan to replace it soon (probably gonna be one of my last replacers), since I improved and aligned the sideposition replacing the original MLA.  Theres really no need for 2 sidepositions.

I think Cupid has a total of 27 positions with this plugin (definitely feels bigger).

Installation;

Just merge data folders, but please Back up your Data. Because I am new to the CK and papyrus,...and you can bet I wont know much more than you about a problem. I will try to help, but I don't know much.

Generate FNIS for USERS - 100% Required  - along with SexiS and anything SexiS requires (SKSE ect.)

Installation (for SexiS Replacers)

Simply merge the data folder from the .rar file with the data folder in your skyrim directory. 

​(Running FNIS is unnecessary when replacing animations) 

Note: Back up your SexiS folder in the skyrim/data/meshes/actors/character/animations directory in case you decide you want the original SexiS animations restored.

Uninstallation (for SexiS Replacers)

Overwrite the animations in your SexiS folder with those in your backup SexiS folder. Or simply redownload the original SexiS animation folder and overwrite the animation files.

SexiS Replacer Downloads: - All of these animations are in the BBP extension mod.
