Why make this mod?

3BBB is a great mod, but the default CBPC physics is not as smooth as SMP.
SMP is secondary and always has to be added with scripts and it uses an armour slot.
Needs to be patched or it will be unequiped by certain mods that force unequip armour.
Also most importantly, SMP physics do not work in first person!
With improved camera, it is a crime to not get beautiful physics in first person.

Performance: Yes, this mod adds SMP to every single female character,
but physics only happen when NPC are naked.
You have to manually patch clothes and armour with this mods body to use SMP.
Otherwise any armour with breast bones will only really use CBPC.
(Which is not extremely demanding).

Requirement and Installation Guide:

Install FSMP - Faster HDT-SMP.
Then install XP32 Maximum Skeleton Special Extended - XPMSSE,
FOMOD options: Pick Extended, then pick XMP(S)E 4.51 or Latest
(Try latest, if any animation is messed up. Switch to 4.51.)
and then pick NONE for all other options.

Then install and run Project New Reign - Nemesis Unlimited Behavior Engine.
Download this mod and build with bodyslide studio the body, hands and feet.
Check in game and enjoy your physics.

My recommended CBBE 3BA (3BBB)'s Physics config is included in this mod,
full SMP for most body parts, but CBPC should still be installed,
because some areas still use CBPC.

Alternatively, you can also install the CBBE 3BA Physics Config Reinstaller from CBBE 3BA (3BBB)'s optional files to setup your own physics preset.
Just make sure to open each SMP .xml file with Notepad++ and use the "find and replace" option,
to replace all "triangle" with "vertex". There is very little visual difference, but you lose less frame per second by doing so.
I only tested with SMP full, still not sure if just CBPC will work. Feel free to test and see if only CPBC works with this mod.
Also you can and should delete or deactivate the 3BBB.esp, it is not needed with this mod.

Install Mu Joint Fix (Knee Fix dll edition) aswell for better knee bending.

Along with most recent 3BAv2 body with verison 2 sliders with SMP collision and physics attached from Acro's CBBE 3BA (3BBB),
I also included hands from Artsick's Female Hands Redone
and feet from NecDaz Feet both with updated zaps to match the 3BAv2 body.
Only the nude model is included, all clothes/armour with hands and feet visible needs to be patched.

Compatibility:

Works with or without CBPC - Physics with Collisions for SSE and VR.
Having this mod does not seem to conflict with SMP body physics.
I recommend downloading it as well for SOS flopping to work.
Also seems to be required for TRX SOS addon.
When you do download it, just let my mod files overwrite it.

Note: Feel free to edit the xml files, if you know how and more.
Most of the ones included here are just existing preset mash together.

Credits:

All credits go Acro, Artsick, NecDaz3D, Regenbot03, Ousnius and Caliente for all their assets.
Tools used: Outfit Studio x64 and Nifskope 2.0 Dev 7.

Extra information:
Only human female support, no beast or male support for now.

All I did was combining them together into an alternative mod similar to SOS light that is neither better or worse.
I am simply offering another choice for setting up physics enabled female bodies.
Donation points will not be enabled regardless if I get direct permission or not.
I am sharing this mod, because I wanted something similar to FO4 3BBB Physics body without the need for MCM and armor slots to exist.
