wip Real-Time Body Physics (DirectX 11)

[alexlll]

@CPVC  I'm really looking forward to the RTBP Commander v0.2 I hope there will be settings for the left and right chest and the ability to save the settings. I have disabled the settings for the male penis and buttocks, but sometimes the finger hangs down for men, (it's good that it's not middle) :-))

Some 'jiggle' settings for folks who prefer that with v0.4-p2

@CPVC Hi ! I'm loving your work and I must say it's quite ambitious and really adds another layer of love to the game. The mod works great with boxers and trousers.

My only issue so far is the lack of physics around the lower part of the butt and no physics at all for the penis/balls (I don't know if they were supported already), I only use the mod for males and I have this mod for bottom/penis :

Is there a way for me to fix it manually ? or is it something hard coded ? If I can, I'd like to help!  I've attached a video so you may better see the problem.

 

Oh, and the RTBP commander works great x I would recommend to add it in the list of files, I had to go through the entire thread to find it haha
 

 

At this time, it's hard coded, and the algorithm is very primitive. I'm working on a better way of creating new bones on the fly. In the future, modders may be able to release custom weight maps with their meshes (I'm working on a Blender plugin), but I'd like to figure out a way to do it automatically based on the positions of the body parts. I'd like to automate this as much as possible.

Split settings will be an (optional) feature of RTBP Commander v0.2. You'll be able to right click on a slider and select the "Split/Join Sliders" option from the context menu to toggle it.

 

As you can see from this screenshot, the "Mass" setting has already been split, and I've right clicked on the "Gravity" setting, showing the context menu.

 

As for the finger issue, this is a known problem. I think it has something to do with accessories like rings or something.

[CPVC]

Alright! Would some of you mind trying out RTBP Commander v0.2? If you're up for it, please test it out and let me know if there's anything wrong with it. This build is statically linked, so there are no external DLLs required.

 

Let me know if something isn't functioning properly and I'll fix it as soon as I can. Thank you all so much!

Looks nice, just a quick question where does RTBP Commander install???

Version 2.0 works fine. The division of the breast into left and right helps a lot, save also works. The only thing I would like to fix is the settings of the sliders, the default maximum values are too high, the Tick Interval parameter does not work yet, if I set it to 1, it still works like 0.1.

P.S. Could you make the breasts swing indefinitely when testing the x y z axes ? (The button is pressed - the chest swings, pressed again - stops). This function is very convenient to use when using animations in which the chest is motionless.

RTBP Commander doesn't need to be installed anywhere. You can execute it from any location. Just make sure RTBP is installed and the Sims 4 is running.

 

RTBP Commander will (should) connect to port 8008 (BOOB) and allow you to communicate to RTBP, via RTBP Commander.

If you set a simulators "damping" value to 0 and execute the test command, the body parts should swing back and forth indefinitely.

 

Everyone else: I'm making progress implementing 3D weight maps that can be applied to meshes at runtime. These are made and fine-tuned in Blender, then exported as files that can be loaded by RTBP. 

 

This will most likely be the default way of adding physics to body parts that don't exist yet in the future, like the butt and dick. It's much more accurate and customizable compared to the current method and will make it much easier to add new body parts.

Thanks it works. But I would like to be able to fine-tune this moment, so that it would be placed in a separate category with its own settings. It seems to me that this will be a demanded function, and if you turn on the random switching of the xyz axes, it will be generally ideal.
I would also like you to add a button for loading settings in RTBP Commander.

Hmmm... So maybe a command where you can put RTBP into a sort of "range testing mode", where the body parts will bounce back and forth continuously on a certain axis and every couple seconds or so, the axis changes? Is that what you're thinking? I'm not sure I understand completely.

 

As for loading settings, you want RTBP to be able to load custom setting files that aren't located at "RTBP/Settings.ini" at runtime? Is that correct?

Your mod works great for in-game interactions but when sims have sex it is not so noticeable, a lot of animations have bad chest physics, enabling the "range testing mode" command greatly improves the situation. If you could learn to recognize ww animations and automatically add breast swaying to them (you can do without physics) that would be great.

 

When i load RTBP it doesn't separate the settings for left and right chest and I have to enter the value manually. Load custom setting files that aren't located at "RTBP/Settings.ini" this is a great idea.

I dont have a README.html file in the download

Update: I figured out the installing part but it says (cpvc could you send me the README)

Installer failed!: filesystem error: cannot rename: No such file or directory [C:\Users\lieor\AppData\Local\Temp\d3d9.dll] [D:\SteamLibrary\steamapps\common\The Sims 4\Game\Bin\Game\Bin\d3d9.dll]

I think you may be using the wrong ZIP file. Please go here:

(^ This happened automatically.)

 

Click the button labeled "Download this file". After a file named "RTBP v0.4-p2 2021-09-11.zip" is downloaded, execute the RTBP Installer and select "RTBP v0.4-p2 2021-09-11.zip" as your RTBP ZIP File.

 

This ZIP archive should include the README files. Let me know if you have any other problems.

Thanks

Ok, I think I get you. I've modified RTBP Commander to automatically split the sliders when the left and right body part settings differ. If they are the same, it'll be one slider that controls both sides of the sim, but if they aren't, they'll be split into two sliders.

 

I'll also make it possible to load custom settings files.

 

Thanks for the feedback!

Does someone have recent videos or something more updated to look at? I think many people would want to see how it looks in-game and not only in the CAS. And to the author of the mod, a firm handshake and a thank you! You are very talented!

So I've just started using the RTBP mod, and while I encounter some common issues already mentioned here, I'm really satisfied with the results of this hack and I'm actually amazed that we can finally experience body physics without having to mess around with custom rigs and other settings.

I gave it a shot for one of the converted MMD dances, and this is the test result (Btw, modella converted it to Sims 4, but I also make Motion conversions):

the butt physics make my game crash do you need all the packs for this mod run properly 

[GhostJ27F]

holy shit!, how  did I not know this existed! 

 

I love it! patiently waiting and for it to progress and able to use on other top and bottom body cc.

 

[ToxicCG]

Something seems to be wrong with my installation even though I follow instructions to the letter.

It's the d3d9.dll

The game simply will not launch with the one in the RTBP zip file, no matter what I do. It was working fine before I purchased the most recent expansion, but after installing it the game refuses to start with RTBP.

I'm not sure, actually. RTBP hasn't been tested with all versions of the Sims 4. I've always developed RTBP on the latest version of the Sims, so it's possible that it won't work on older versions. Could you post your log file? It might offer me some insight into what's going on.

Do you get any error messages when you try to launch the Sims? If so, what do they say? Thanks.

[ToxicCG]

No, it just starts and crashes. No messages. The process just terminates.

[poplan]

This is probably not possible due to the way this works but if there was some way individual Sim settings could be done that would be awesome.

Regardless of whether CPVC addresses this in the next update, this problem can be fixed immediately by using their program "RTBP Commander" (it's on the main download page) to disable Male Butt Physics. Obviously this means you lose that feature of the mod, but if you're like me, you're more interested in the females having physics. I was experiencing the same issue until I tried this.

problem persist with male physics off .. i see this problem caused by some shirts.. upper body clothes

Damn... Well, you're not the only one having this problem. I'll try and improve debugging even more so I have a better idea of what's going on.

That is something I hope to implement eventually, but I haven't found a way to associate sim buffers with individual sims yet. Still working on it, though. Stay tuned.
