wip Real-Time Body Physics (DirectX 11)

[l0ngdickj0hns0n]

The last couple updates have seemed to fix a lot of the bottom physics problems with different meshes. That flat-chested female top mesh is no longer bouncing yay! Definitely has something to do with how the mesh is created, that changes if it works well with RTPB or not. Some seem to push the mesh beyond the maxis original mappings so that RTBP see's it as like a hard outer layer of clothing that the physics should not work on. (thinking modding other games like Skyrim, if you snap an outfit to your character that isn't built in bodyslide for your chosen body, then it is stale with no physics and usually the wrong shape, so it "works" but not with the physics you're trying to have it work with) So I'm thinking this is probably the issue between body part mesh creators, and why some work great and others have issues. I have messaged some body mesh creators and linked them to RTPB in hopes that going forward it all gets better.

 

 

Thank you so much for continuing to update this mod. It is an absolute must have for naughty sims 4 modding IMO.

The problem with the commander ought to be fixed now. Please redownload the GUI Tools bundle. Thanks.

 

All good now thanks

Hey is it at all possible to get Gshade to work w this? 

 

 

[BabyBellies]

Can I have previous version that was still compatible with reshade?  If anyone has it

Not at this time. It was working before, but something changed, I think on the ReShade/GShade side. I haven't really touched the hooking code much, so I have to assume a change on their side broke compatibility. When doing research, I found a post by the developer of ReShade saying that trying to chain load faux Direct3D libraries like RTBP and ReShade together likely wasn't going to work. Why it worked for a while, but doesn't work now is beyond me.

I'm not certain that older versions of RTBP will work with ReShade/GShade in it's current state.

This mod is a game changing experience. Thank you!

 

The mod works almost perfect except a few problems on male sims for me.

My setting.ini is in the attach files.

 

With some clothes, the male sims will be affected by the physics. Despite I disabled all physics on male butt and balls in the "Setting.ini".

There are many of them, but I would pick some out for example.

 

In the base game "Tops > Suit Jackets" the bow tuxedo will let the whole chest shake like Monkey D Ruffy.

 

Under the base game "Tops > Suit Jackets" this one will let the shoulder shake.

 

This Apron in Dine out will let the belly shake.

 

This Apron in Dine out will leave a gap between head and let the upper chest and shoulder shake.

 

I suspect It is caused by those cloth models settings.

 

Most of them just make me chuckle, except the neck gap one bothers me a bit.

BTW the Male body will not affect by physics when naked as expected.

 

My game is heavily moded. I am not sure this is solely caused by this mod.

I would like to know if anyone have the same problem?

Monkey D. Ruffy (lol) (that's reference to an anime/TV show called One Piece, for people that don't know what he was talking about)

 

I mentioned this a couple of times in here already - I have a similar issue and I've specifically mentioned that tuxedo, for example.  It looks heavily distorted in my game (amongst a number of male tops).  I have recently modified males a little in my game, but it was doing this prior to me even modifying males at all when I was using defaults.  It was solely a result of the female breasts physics being enabled.  I know this because all I have to do is disable the female breast physics in the RTBP .ini file and it fixes the issue.  In your pictures I don't even see a distortion.  In my game, it is badly distorted.  Like, the area between the neck and shoulder dips down to upper bicep level and then bounces around like a massive floppy breast.  On some male tops it only does it to one shoulder, but then others it does it to both...  OK, here's a pic (lol):

 

 

For comparison purposes with a male top that looks ok (not like you need it though, because the issues are very obvious):

 

 

One with both shoulders messed up (and this one happens to be a unisex top that is also marked as feminine, apparently, though there are other masculine-only tops that have a similar distortion):

 

 

Oh, and here is that same top as feminine on a female (actually does the same distortion):

 

 

And I might as well show a female top that looks good:

Could you add a custom button to turn RTBP on/off ?

 

That would be an excellent feature - where you can quickly just disable/enable the physics altogether universally.

 

Or have a feature of being able (like Wicked Whims method with body mesh mods) to apply to an individual sim or groups of sims.  And/or combine this with the .ini file and commander it uses to have specific physics settings (on/off or gravity/mass/etc levels) per sim.  That way you can disable it for sims that wear clothing that doesn't work properly with the physics (see my previous post), or you could basically customize the hardness/softness of one sim's breasts/ass versus another - this would be a GREAT feature, actually.  Big firm fake tits would move differently than big soft real ones.  Floppy tits would move differently than plump perky ones.  Tiny tits shouldn't really move much at all, etc.

 

This feature is needed.

You can actually disable/enable RTBP through the commander or via commands sent through the console, but I'll look into integrating RTBP into the Sims 4 interface in a more user-friendly way.

 

As for customizing the physics on a per-sim basis, that's always been something I've wanted to do, but I haven't been able to reliably associate individual sims with the incoming vertex data.

 

It's very complicated and I'll spare you the gritty details, but yes, this is something I'd love to do, if I can figure it out.

None of the current versions of RTBP work with reshade 5.x, where versions prior to 0.6 of RTBP did, which is why I've not updated. I haven't tried Reshade 6.x, as I have no need to. I've attached the version of RTBP I'm using.

It is not necessary to use reshade. If you have a video card from NVIDIA you can use NVIDIA Freestyle.

For basic filters and basic adjustments, but I want to use UI masks, custom shaders, and make adjustments I simply can't do in the Freestyle UI.

I have this same issue. You can use MCCC as a workaround and exclude these tops, but that can be very tedious.

 

Also to CPVC if you see this, I understand that fixing this mod takes time. I would donate to a patreon if you had one, knowing it would help free you up to develop this. As a long time user of this mod, I can say that it's unlike any other I've seen and I'd love to see it to its fullest potential. I am facing many issues from the butt looking distorted, this shoulder issue, and not being able to run this with reshade.

I have been using your mod for a very long time, very appreciative of your work!

 

Recently I had to reset windows and lost a bunch of mods, reinstalled them from a backup drive. But I had to redownload the newest reshade 6.0 + RTBP - Currently it's not functioning properly. I managed to get it working a little bit by using the installer wizard, but something is off... There's almost no movement now with my custom settings file which I have been using from Nexus "My_Personal_settings" for about a year, was really good before!   And now, when I enter CAS and view sims topless. Their jugs are stuck facing the camera almost no matter which way I turn my sim.

(looks as if her bobs froze mid-turning 180 very quickly)

 

Reinstalled correctly, followed steps on how to install with reshade, came here and saw other posts about this being a current issue...

 

Would you be able to post a safe link for a previous reshade that works?

 

Edit: I believe 5.6 was working for me

 

Trying to go back to previous versions of things but I don't have the original of everything I need to make this wonderful mod working again!

Now that's weird... Anyway you could post your log file?

 

As for Reshade, I'm not sure which version was the last that actually worked well with RTBP. I don't use ReShade, so maybe someone else can answer that question for you? In the meantime, getting ReShade working with RTBP again is one of my top priorities.

 

Edit: Wait, are you sure you have RTBP installed correctly? The RTBP d3d9.dll is around 27MB. Your screenshot shows that you have a d3d9.dll that's around 4.5MB.

Edit: to be more specific I kept the default d3d9 in the bin folder and placed/renamed the provided one into the log/settings folder

 

I'm pretty sure I placed the d3d9 inside the same folder as the log/settings files and the game flat out refuses to run (no windows errors just fails to boot) I can get it working using reshade 5.7 but it's interfering with reshade and boots up without reshade active. If I just remove the reshade.dll out of the log/settings folder and use the default d3d9, I use the settings profile below:

 

*also, strange I can't seem to get it working with both ReShade and RTBP sense I did find the achieve for all reshade installers, can't remember how I previously had both working it was such a dream! 😭

When puttin d3d9 file in the RTBP folder, it started to bug out with reshade. Before when the d3d9 file use to be in the game directory it was fine but when it moved to the documents folder it seemed to not work with reshade anymore. I dont think its reshade, but where the directory of the d3d9 file is whats affecting both mods. It was perfectly fine, we jus had to rename the shade file to reshade. The reshade d3d9 is around 4-5 mbs. RTBP d3d9 file is around 27mbs

[blepz]

I'm also getting the weird sagging shoulders on dudes.

 

 

And also the female butts are blocky when nude for some reason.

 

 

 

 

 

This is all with default settings and bare minimum mods installed. These photos are from just having WickedWhims + TMex's Better Exceptions + disable telemetry + RTBP installed. The male shoulders even still sag when this is the only mod installed. It's only on certain male tops but quite a few of them.

 

[JMAN_JUSTICE]

After doing a batch fix to disallow cc for random, I now get an Access Violation Exception whenever loading into a save. I deleted RTBP and tried again, the game crashes upon loading a save. I redownloaded RTBP and the game now crashes upon loading.

[CPVC]

Might as well get everyone up to date. RTBP v0.4-p7 has been released, along with the latest builds of the GUI Tools. No major changes, just some refining and improvements. See the change log for further details.

 

Some problems still exist. ReShade still isn't working and the butt is still a bit frumpy, but somewhat improved as far as I can tell. Those two issues are still my highest priorities and I'm hoping I can get them fixed before the next preview release.

 

Thanks for trying it out. Let me know if there are any problems.

 

Edit: Another big issue that's on my mind is the missing shadows issue. This is another entry on my todo list.

Hi, nice mod, but the default settings in the "RTBP" folder for the breasts are really bad, shaking so intensely it's like they're having a constant seizure. Of course I don't know if it's only in my case or common for everyone, maybe you guys could provide better options to change in the file.

 

 

I used in-game recorder and for some reason the quality is the worst , but I hope you'll be able to see the display of what I described.

Whoops, I accidentally left the experimental angular physics enabled by default. That's what was causing the shaking. The problem is fixed now, please redownload.

[alexlll]

For me the latest version of rtb works poorly, if in stock the chest movement does not occur at all if you use test mode 1 and 3 physics appears but it works poorly, I return to previous versions.

 

[l0ngdickj0hns0n]

This last update seems to go the opposite direction for the butts. the wicked whims default has no physics now, and has warped shape. And now most of the other butt meshes also have warped shapes, and no physics as well. I'm gonna put the last .dll back in for now and await the next update.

 

Thank you for always working on this. Everyone loves bouncing bewbs and booties!

Whoops! Noticed another little bug. Please re-re download. Sorry about that.
