new error. happened after a with ui i noticed. i can load into the neighborhood but the second i try to load the family i was using the error appears.

 

Hmmm... Unfortunately your log file doesn't offer any super useful information. At least I know where to start looking, though. I'll take a gander and see if I can figure out what's going on.

Everything works fine in regular sims, but during WW animations i have these issues.

when it comes to adjusting the butt physics it's quite awkward, since it works well horizontally(side to side, sim standing upright) by adjusting X and Z.[limits are adjusted too to max ranges]

my issue is when i adjust Y there isnt really any vertical shifting whatsoever, angular damping i lowered and there still isnt so much upward bouncing on my end.

Try adjusting the max Y and the spring K. Also, remember that gravity is constantly acting against the positive Y axis.

Due to the fact that the programm is not writing a log file I can't post one. However I'm using the Sims x64 version via EA app with the -dx9 parameter setting

I have exactly the same problem but nobody answers to it

Do you have write access to your log file? It should be located at "C:\Users\[USER_NAME]\Documents\Electronic Arts\The Sims 4\RTBP\Log.txt".

Are you using OneDrive? I guess RTBP doesn't play well with OneDrive for some reason.

[CPVC]

Well, how do you like that? I think I've got it. It's looking good. Real good. More testing is needed, of course, but it appears that all aforementioned problems have been resolved. Attached is a preview of RTBP running under DirectX 11.

 

I'll make this public once I'm sure everything is working correctly. In the preview video, only breasts are targeted, but now that I've got the fundamentals down, adding all the other body parts should be a cinch.

Hope it works well with the new memory boost enabled when released. Only reason I care about switching to DX11.

[alexlll]

Thank you for your work! The most important thing for me is to retain the ability to fine-tune breast movement along all axes.

[Onideku1]

Excited to hear it's working with dx11! Is it possible that this mod could ever be expanded to work with custom hair/clothing physics bones similar to SMP for Skyrim?

Oh thank heavens! <3 I knew some good news was coming soon. thank you for working on this update , I'm so hyped to get my game back the way it was lol

Is there a discord or something about this? I have been having issues downloading this and would love talk to someone to get it to work

No, not at this time. You can get help here, though, or feel free to send me a message and I'll help out in any way that I can.

Hi, RTBP Creator, The RTBP Installer said everything is fine but the Commander is "Unable to connect to RTBP" and my log does not exist.

I bought a few packs and installed a few packs from Anadius; therefore, I have 2 folders "Game" and "Game_crack". I copy the d3d9.dll to both of the folders. First, I put the d3d9 in main Game folder and the game crashes. When the file in both folders, game runs but unable to connect. Please help. Thank you.

yes, I am not sure why. I used RTBP before (more than 1 year ago) and everything worked. But now I have both the official and crack game folders, maybe it is the reason. And there is an update in dl recently.

So I browse the discussion here and mine is working now. I change back to dx9 and turn off the Internet while playing. Hope this help.

Yeah, you need to run the DX9 version of the Sims 4 at this time. Sorry, about that, I need to update the documentation. (There is a little note about it on the main page, but easily missable.) If you run the Commander first then go to "General" -> "Start the Sims 4...", it should automatically find and run the DX9 version of the Sims 4 for you.

 

Alternatively, you can change to DX9 in the settings or just execute "TS4_DX9_x64.exe" directly.

 

DX11 support is nearly ready. I just need to take care of one little stubborn bug. Other than that, everything is stable and working as expected. I've played for hours with it and other than that stupid bug, everything seems good.

It keeps telling me "RTBP Commander was unable to detemine your Sims 4 Executable file. You will need to restart Sims 4 manually, the commander should connect eventually"

you need to find your filepath for the game and add it so RTBP can run. copy that filepath into the commander. its wherever your TS4.exe file is and then restart the game and restart the commander after

Hey, I don't find anywhere I can link the filepath. Do you mean to link it to that place in the "load setting file"? 
I have done the RTBP installer like 3 times now

Can I see your install log? After you install RTBP using the installer, a window will pop up with a bunch of text. That is your install log. Copy that text, save it as a text file, and post it here.
