wip Real-Time Body Physics (DirectX 11)

[Kodenu]

The latest .dll fix seems to have worked. Played for a couple hours and no problems popped up.

[markroot]

The latest dll is ok, but Reshade d3d9.dll in the RTBP folder is not work, the previous version is normal

@rukasulucas Interessante, tenho baixado cada atualização para ver o progresso, mas não vi nenhuma diferença no jogo. Eu me pergunto se isso vai mudar para mim quando eu criar um novo sim. Eu faço o download dos arquivos zip e os extraio em Arquivos de Programas (x86)> Jogos Orgin> The Sims 4> Jogo> Bin_LE.

 

Pelo que li, não preciso fazer mais nada para que o mod funcione, espero que possa fazê-lo funcionar. Vou tentar criar um novo sim e ver o que acontece. Saúde a todos. 

I replaced the d3d9.dll with the d3d9.dll fix and now it works on most of them

@rukasulucas Interesting I've been downloading each update to see the progress but I havent seen an in-game difference really. I wonder if this will change for me once I create a new sim. I download the zip files and extract them to Program Files (x86) > Orgin Games > The Sims 4 > Game > Bin_LE.

 

As far as I've read I dont have to do anything else for the mod to work, I hope I can get it working. I will try creating a new sim and see what happens. Cheers all. 

Yes, as others have said this mod only supports the 64 bit version. If there's a demand for a 32 bit edition, I could release that along with the 64 bit edition, but if you're using a computer made in the last 17 years, your computer probably can run the 64 bit version of The Sims 4.

Oh, I forgot to mention, I changed the way compatibility with other hooks works. So take your Reshade "d3d9.dll" and rename it to "d3d9_2.dll" and leave it in the "Game/Bin" folder. Install my mod and run the game. Hopefully everything works, I haven't tested it.

hi!i try Reshade "d3d9.dll" and rename it to "d3d9_2.dll" , copy to game/bin  ! it is not start game

Dang. Well, I guess I'll have to do some more experimenting. Thanks for the feedback.

Main bug for me is a gap appears in the mesh for male bums, from what it looks like just preventing the physics from affecting the (seem or top set of verts on the male bottom mesh) would fix this. I think its related to the fact female bottom meshes come up higher, all the way to the waistline and males stop at the hips.

Hopefully its possible to have different verts being affected for each gender.

Here's a picture to show what I mean:

Yes, I have noticed this as well. The problem is that the top and bottom of the sim are different meshes and are stored in different vertex buffers.

 

It is possible that these different meshes share bone information, but more research is required. If that's the case, then I could group all the vertex buffers that make up a sim together and have them share simulators.

[Tortex]

Seems good, mostly. Breasts work wonderfully in CAS, but tend to stop in game, sometimes I get double mesh shenanigans. Ass always works well. Not noticed any unusually behaving vertices now though.

I don't know for sure that they do share bone information, but if it helps any, teen-elder both genders all use the exact same rig(bones) with some minor posture adjustments.

Sometimes when i enter the cas editor i see some butt wiggle but it stops immediately. Ingame there are only gtliches like that but they dissapear when i change clothes. In this picture the glitch appeard after i went down the stairs. Otherwise nothing moves.

[CPVC]

Alright, I'm going to call this the next official release. I know it's not perfect, but I want to get the source code out there so people can expand on my work.

 

RTBP v0.3 is live, with documentation and source code.

 

v0.4 awaits, with a lot of preview releases in between. Giddyup!

 

Real-Time Body Physics

[Tortex]

Really appreciate it. I love stuff like this and it gives me an excuse to poke at this 26gb VS++ install I ended up with.

[nobodysfool]

Does it conflict with Tonicmole's mod?

[LoveOnTheFringe]

I cannot wait to see this come to fruition. I will have to tinker with the settings to adjust the breast physics to my taste but the butt physics work so well right out of the box! 
One thing that always annoyed me with sim bodies was when females would lay on their back in animations their breasts would still stay firm and bouncy and in place. That is not how real breasts work unless the woman is either very fortunate or has implants. I was absolutely elated to see that when my sim was on her back, her breasts actually flattened out and looked natural in that position. WELL DONE! 
I am looking forward to more body part being implemented into this mod. Especially the thighs, bellies, upper arms too! I know everyone wants wang physics, and those are very important, but I would love subtle ones as well like lips (can you imagine how nice kissing would look?) earlobes, maybe even cheeks and jaws. I hope that adding those would inspire more animations of an intimate nature. Of course it goes without saying that orifices would be amazing too. Vaginas that act like vaginas and not coin purses would the bees knees for sure. 

One question tho, before I start tinkering. How much of the breast movement with WW is dependent on if the breasts are animated already via the actual animation. I noticed varying degrees of movement depending on which animation was playing and wanted to make sure I understand this before I start changing anything in the settings.

I have the same problem, it works in CAS, but in the game it doesn't. Nothing bounces, but glitches in household pitcures are visible. I am not bothered by it and I just want to make it work. I tried every version, it is same everywhere. 

[GrimCreeper1647]

idk why i dont have walking boob physics 

and i dont have butt physics, shouldnt the boobs flatten when laying??  my pc isnt letting this work or something

[pihwht]

Works fine for me, both butt and breasts. Breasts do tend to bounce in and out instead of up and down. Occasionally, something untoward occurs: garments grow a triangular tail, or buttocks rise up into a pair of unsightly humps if a player character is nude. Deformities disappear if the outfit is changed. Non-household npcs haven't shown the tails or the humps.

[cableguy7uk]

Noticed that too think I'll  reboot game

I've noticed this as well. Fixing this is now my number one priority.

Hmmm... So vertex selection is based on the default (Maxis) meshes. If you're using a custom default mesh via a mod, it may not work, because the positions of the vertices are different.

 

I'll work on it.

[Oops19]

Does getClosestVertexToTextureCoord() actually work? It seems to be the better way to get the vertices as the position on UV maps do not change.

Which mods could cause it? I removed sliders, custom feet, nipples, bouncing boobs mod.. It is the same, when I create in CAS, it works in the beginning, but when I click on other type of clothing for example when I click from everyday to formal it stops and is like that entire gameplay. Sorry for bothering you, but I really want to make it work. 

[Tortex]

This is what I ended up with settings wise:

 

[rtbp.leftBreast]
mass=0.6
damping=16.0
springK=250.0
maxLength=0.16

[rtbp.rightBreast]
mass=0.6
damping=16.0
springK=250.0
maxLength=0.16

[rtbp.leftButt]
mass=0.2
damping=15.0
springK=350.0
maxLength=0.16

[rtbp.rightButt]
mass=0.2
damping=15.0
springK=350.0
maxLength=0.16

 

Small breasts are perfect. Butt movement is fairly subdued. It tends to go apeshit in CAS and explode, dropping FPS from 200+ to 13. It seemed, to me at least, restricting max length and going hard on the dampening stopped the z-axis forward/backward tomfoolery. (Uneducated number changing.)

 

Does Sims not use a normal base skeleton for humanoids with specific, identical bones or is it defined in the meshes or some such?
