OCBP for Fallout 4

[Crowzer]

I just updated Fallout 4 to the last version, V1.11.191 Anniversary edition ; and why the old ocbp.ini works and the new one does not ? With the new .ini file provided from the last update of OCBP (thank by the way), the body part as boobs and butt are not moving.

By old ocbp.ini I mean : https://imgur.com/a/TAXhHoS. and new one : https://imgur.com/a/6oYbnVt

Thank you.
The problem with closing LOOKSMENU has been fixed and it now works without any problems.
Since I'm using Fusion-Giral, I changed ocbp.ini to the one from OCBP_3.1.2_FG.

hi can you tell me how to change the ini like this.  I am using fusion girl

Hello! Make, please,  a papyrus function, which would allow you to create an effect forcibly from a script:

Function PushActor(actor act, int timer, int power, bool breast, bool butt) global native

hi,
i use the latest ocp (with fg - ocbp.ini). so far all works fine
thank you

 

may you help me understand following:

i try using Immersive Wastelanders ( https://www.nexusmods.com/fallout4/mods/19544 )

got that dark head ingame - so i just reinstall this mod

after that the head looks as it should be

but physics are total mess, breast,butt,etc. have that anchors and wierd spikes

how is/could this be related?

Interesting question, I see the bone names are present, maybe the real difference is in the bone parameter section.  There are so many parameters, and IMO what looks right depends on how much mass you are expecting to see.  the system has no idea how big your mesh is, it just moves the bones.

That sounds like a skeleton issue, check your skeleton deployments didn't get overwritten by that redeployment.

If you could DM me your INI file, I'd like to see if I can fix mine? thanks.

That was an AWESOME idea!  Their physics code limits the number of actors being processed, and has a stronger tie to FPS. it runs *Much* better on my system, subjectively. Also it brings some Mod Configuration Menu support, in a non-required way, for most of the [General] section. 

 

Here is Release 3.4.191 of OpenCBP for Fallout4. 

 

Install Instructions: 

- Requires F4SE 0.7.7, Fallout 4 1.11.191
- Disable old package or conflicting previous release CBP family mod
- If you have customized OCBP.ini, back it up and review the new INI after installation

- Install this package with Vortex or MO2.  

 

 

Changelog: 

### 🔧 Merge from Worthless99’s “FPS Fix with MCM Menu” 
- Mod Configuration Menu integration  
- Physics optimizations: FPS fix  
- Physics performance tuning: max actors, activation/deactivation distances  
- Removal of AMP  
- Logging improvements  
- General code cleanups and modernization  
- Really great for performance!

### 🔨 Additional updates:
- Version resource created for DLL  
- Revised logging system:  
  - Runtime toggle: `loggingEnabled=false` in the INI disables logging  
  - Deduplication: repeated messages are collapsed  
  - Runtime toggle: `logConsolidationEnabled=false` disables consolidation  
  - “Error” level messages are now labeled as `[Notice]`  
- Config changes:  
  - `tuning.rate` removed (no longer used)  
  - Revised master `OCBP.ini` with documentation and valid parameters

Same issue as me. Reinstalled everything, wiped all mod/game data from pc and now NOTHING works. Even tried using Zez skeleton and fusion girl and still nothing.

Hey there, I actually found a way to install the update with MO2 (in a roundabout way, but it worked for me!).

1. Download OCBP 2.2.5.zip
2. Extract the .zip file to its own folder
3. Download OCBP 3.1.11.191.zip
4. Again, extract the .zip file to its own folder
5. Open OCBP 3.1.11.191's folder, then copy the cbp.dll file inside
6. Open OCBP 2.2.5>Data>F4SE>Plugins, then paste .191's cbp.dll and let it replace the original 2.2.5 cbp.dll.
7. Delete the original OCBP 3.1.11.191.zip, then rename OBCP 2.2.5 to OBCP 3.1.11.191 .Then compress the renamed folder into a .zip file
8. In MO2, click the disk icon aka "Install a new mod from an archive". Install as normal.

Enable the mod, then you should be good to go! I'm brand-new to FO4 modding, so I too struggled to install the update manually. Let me know if you need anymore help!

Thanks man, you are a life saver

Hello! Im trying out this physics mod, i only used physics mods on Skyrim with 400 mods in my list. Now trying out for Fallout4, previously i had max 120 mods, but now expanding. So i had quite hard time to install CBBE together with BodyTalk cos of ZeX skeleton issues among other problems with sliders and morphs, but now ive done it and can move on to physics.

 

My question is - should physics work like this?:

 

https://imgur.com/a/8FmdMac

As you, hopefully, can see - they are bouncing up and down 3-3.5 times (from down to, up, down, up, down, up, down) in the same direction, speed and  general vector each time, which makes it look unrealistic. This gif slowed down the time by about 3-5 times. In reality this jump takes 0.8-1 second, so the jiggling looks too fast and not linked to the movement of body. Sometimes it even looks as if it was twitching because of 3-4 times bounce in less then 1 second.

 

In skyrim they were much prettier, especially with bathing mod, and collisions mod, my female PC was moving her hands and sometimes touching her boob and it slided up and bounced back down very realisticly. But this seem much lower quality then that. Did i install something wrong or didnt install something enough? Im on 1.10.984 NG version. I am using those mods for body replacement and similiar things in this order(im sorry i dont know how to use spoiler function on this website to make picture smaller):I was trying with MTM 3B OCBP physics collision preset and without. With it jiggle is barely noticable, when jumping up. Without is how it looks in the upper posted gif picture on imgur.

 

Is this how it was intended to look?

I assume you updated the game to the latest version 1.11.221 which every update breaks every f4se plugins. At least me being an idiot who forgotten about that after a few months without any problems...

 

Now i just wait and hope someone can update ocbp, since i don't know how and want to downgrade the game.
