I'm seeing at least 10 downloads for 2.3.1~3 and no error reports submitted. Does this mean the problem has finally been solved? Let me know what's up.

 

Took me a while because I had to clean up a shit ton of mods before I could start a game, but with the latest one I don't crash anymore. Also, does tweaking the settings of the balls do anything? I can't remember one instance of downstairs bounce since v1 of rtbp.

Nice, if that takes care of it, I'm going to release another minor version. I get a hand full of error reports every day with the same problem and if it's finally taken care of, that's great, I can move on to something else.

 

And yeah, balls physics are currently disabled. They were causing problems and need to be worked on.

I'm really glad you found the problem. At least, it looks that way. Thumbs up to you and your work. 👍

Is the official version the same as the latest test version from this forum?

It looks like an antivirus program or firewall is blocking communication with the mod. Just a question: when you place the DLL into your 'bin' folder, does Windows ask for administrator privileges? You need to run it as an administrator.

No, and the installer says that the DLL is not blocked. When running the installer it does ask for admin priviledges.

work good in normal activities, but very bad/weird in ww sex animations. i think those animations already have those effects put in.

Please check whether your firewall or antivirus software is blocking the DLL. You should whitelist the DLL—at the specific file path—in both your firewall and your antivirus program (specifically the DLL located at `Sims4/Game/Bin/dll`, as well as the mods folder at `Documents/EA/Sims4/RTBP`, if applicable). The `Companion.exe` might also be blocked, so ensure that it is whitelisted as well.

I use Windows Defender and DLL files can't be whitelisted, and the executables are whitelisted.

Are you use a reshade, or gshade ? 

For Win defender:

 

• Open Windows Security -> Virus & threat protection -> Manage settings.
• Scroll down to Exclusions -> Add or remove exclusions.
• Click Add an exclusion and choose Folder. Select the whole The Sims 4/Game/Bin folder. This bypasses the DLL restriction entirely.“ 

 

 

If none of that helps, you'll have to wait and see what CPVC finds. Fingers crossed. Alternatively, you might want to try launching the game without any security measures—basically disabling everything just to test it.

I've tried all that and I used Reshade in the past I don't think I've used it for awhile, however RTBP was working before this recent game update.

Ah okay. Have you tried RTBP without Reshade? I know this might sound like a silly question, but have you selected DirectX 11 in the game settings and are you using the RTBP d3d11.dll? CPVC actually fixed the Reshade issue a while ago. Could you please check the `Game/bin` folder and let me know the exact names of the Reshade file and the RTBP DLL? There might be an error there after all. One thing you could try is this: open the Windows Command Prompt (run as administrator) and type `ping localhost`. If that doesn't work, Windows is blocking the internal network request. That’s all I can think of. If none of that helps, I’m out of ideas—you’ll really have to wait for a reply from CPVC.

I checked the Bin folder and didn't notice any files to stood out as being Reshade, still I decided to delete everything except the RTBP folder and the d3d11 files since I know those are from RTBP, and then repair the game through EA App. I ran the ping localhost command and did work. I'll com back after the game is finished repairing.

So I started the game after making sure to clear out Reshade and RTBP still doesn't work properly.

That's the log for the Python script mod part of RTBP that runs in the game and talks back and forth with the RTBP DLL. Your log shows that RTBP didn't initialize fully, so RTBP isn't listening for a connection from the script mod, hence the error. Why that is happening is beyond me. Any other graphics hooking mods, overlays, or anything that could conflict installed? It's looking like everything is working up until the point that the wrapper is created.

I have some clothing mods, an item upscaling mod, and have disabled all the overlays that I know of.

I've removed all mods except MCCC and RTBP still doesn't work.

Excuse me Which parameters should  be adjusted to lower the sensitivity? female's breast will looks like jelly and shake Pass through the body to back when i play ww animation.

Since a lot of Wicked Whims animations have breast physics baked in as part of the animations, RTBP will respond to these transformations and add physics upon physics which can get a bit out of hand. If you'd like to see animations as the author intended, it might be best to disable RTBP while viewing animations. Press "F11", go to "Breasts" and uncheck "Enable Linear Physics?" and "Enable Angular Physics?" to temporarily disable RTBP's breast physics simulations.

 

If the future, I'd like to add options to automatically disable RTBP when viewing WW animations or override the baked physics with RTBP's physics.

我看到 2.3.1~3 版本至少有 10 次下载，而且没有收到任何错误报告。这是否意味着问题终于解决了？请告诉我具体情况。

Yes, I downloaded your version 2.3.2, and everything is currently working fine. However, I don't fully understand the parameters within it, which can also lead to distorted avatars and breasts flying around

Does this help? I threw this together with Google Translate. I will be improving internationalization in the future, so someday RTBP will come with translation files that will translate the GUI in-game.

I uninstalled and deleted everything, then reinstalled everything and now it works. So I'm confused.

Well, that's good! Sorry I couldn't be more helpful. Sometimes things just don't work for one reason or another.

Physics reverted back to not working again, but this time I figured out how I can get it to work, I'm just not enthused about the solution. If I turn off Memory Integrity in Windows Security > Device Security > Core Isolation then the mod works properly.
