It's weird. Either:
1) The game launches. It goes to the load screen. I click resume and it crashes.
2) The game launches. It goes into the load screen. I click load game and select the game to load, the house and it starts up but during play it intermittently crashes. Ther RTBP GUI       pressing F11 doesn't work so it's hard to tell if it's working. 
3) The game works but RTBP does not. 

I had downloaded NisaK's update thinking that may have affected it. I removed it and I still suffer 1 ofthe 3 mentioned. I do not have DX9 check marked. I am going to try that next. 

Have you tried starting RTBP without any other mods or custom content? The best thing to do is remove everything from the mods folder except RTBP. Then, delete the localthumpcache file located in Documents/Electronic Arts/The Sims 4. If it works then, the problem isn't with RTBP. In my case, it was a custom content.

Hey, im having a issue. So, im using Reshade, and RTBP at the same time. Now, i followed the instructions in the uh downloaded .zip/.rar folder, saying to rename the original reshade dll from dx11dll or what ever to reshade.dll, i did that, put the rtbp mod's dll into the bin folder as well, went to start the game andddd it just.. like my cursor loads, goes back to the ea app and doesnt launch at all. its like i guess it launches then just closes immediately. below is my current bin folder, ive tried several things like changing to direct 9, but im not so tech savvy in that part. I can install mods and stuff just fine with instructions, but when it comes to learning fundamentally what anything does, is what i lack. Is there any way someone can help me with this issue? to rephrase, the game does NOT launch, it only launches if i remove either reshade.dll or the rtbp dll.  im also using ReShade_Setup_6.7.1 to install reshade to my TS4_x64.exe in the bin folder, while using the "RTBP v2.0 2026-01-01.zip" to install rtbp. i used the instructions in the RTBP v2.0 2026-01-01.zip folder, the "Readme.html" file.

I guess ReShade is hijacking "dxgi.dll" now instead of "d3d11.dll", so all you have to do is install RTBP first, then ReShade. All that stuff in the read me is obsolete and I will be updating accordingly.

Ahhh okay, Thank you. so i just install rtbp like normal, then install reshade and dont do anything and it should work? correct me if im wrong but in any thing modding related that sounds a bit TOO simple, too simple to the point where i dont believe itll work out just like that haha, but ill try it a bit later. Ill let you know the results, im not sure if anyone said anything abt reshade and rtbp not working or smth but ill update you regardless of what happens.

Make sure you remove any files you renamed to "reshade.dll". If that doesn't work, post your log file and I'll see if I can help.

I haven't found a solution to your issue yet, unfortunately. I guess I'd just suggest making sure your GPU drivers are up to date for now. Sorry I can't be more helpful. 😞

I love this mod so much. its works flawlessly but I'm having this issue where the game crashed if i try to change window modes or if i minimize. its definitely caused by d3d11.dll. Anyone have any idea?

do not rename it to reshade.dll it will NOT read with RTBP for DX11 ...it reads it without needing to rename. just clear all the cache and switch out the dll for the new one and change your settings for graphicsrules

 

I have posted about this in the thread before for installing both

I was wondering if it was just me but my build mode doesn't switch  back to live mode and freezes or crashes lately soon as the game starts to simulate queued actions and notifications and in game animations, it pauses a long time but the boobs wiggle at hyper speed then crash...I'm not sure if its RTBP alone yet , as I add and remove mods daily but it has started recently

wait sorry can you give me like step by step instructions on how to install? ive tried to install them both as well, reshade first and then rtbp after, with and without changing names, then changed the formation to instead do rtbp first and then reshade, with and without renaming them, but im not sure what the issue can possibly be. and i say this because each time theres 2 dlls from reshade or rtbp it just doesnt launch, like nothing comes up. my cursor just has that loading animation, then stops loading, EA comes up, and thats it. ive also tried alternate formations like renaming it each time i reinstalled reshade, to the names in the read me or whatever, then changed the formation to make it so i install rtbp first then reshade after. but i dont think the formation of downloading would matter, nothing gets rewritten, since rtbp has the d3d11.dll, and the other has a dxgi.dll. ive cleared my cache a few times as well (my local thumb cache) is there smth else to clear as well? also im rereading your message and u say it wont read with dx11, does this mean that it wont WORK with dx11, or that i did something wrong since im running it with dx11 theres a different set of instructions? also, for the graphics rules, are you referring to "setProp $ConfigGroup EnableSoftwareSkinning" to turn it to false? if so, ive already done that before as well.

<< my findings and how I installed RTBP + RESHADE running DX11 ^ click this ^ 

 

 I cannot give you step by step, but if you have already used this mod before only a few things have changed far as installing I can try to troubleshoot & fill in gaps because alot of installation issues can be solved from searching the thread :

 

 ive tried to install them both as well, reshade first and then rtbp after, with and without changing names, then changed the formation to instead do rtbp first and then reshade, with and without renaming them, but im not sure what the issue can possibly be. 

 

you have to install reshade / gshade FIRST. run the game AFTER ..close the game THEN install RTBP  and run the game a second time. 

 

it just doesnt launch, like nothing comes up. my cursor just has that loading animation, then stops loading, EA comes up, and thats it.

 

1ST, I will say I do not use the EA app. I'm a pirate , if you can disable or forcestop this or try to launch TS4 offline might help! just for the install . 

I have heard of people going in the EA app to enable Direct 11 settings directly outside the game also. 

 

then changed the formation to make it so i install rtbp first then reshade after. but i dont think the formation of downloading would matter, nothing gets rewritten, since rtbp has the d3d11.dll, and the other has a dxgi.dll.

 

if you are impatient and have a slower pc or many mods THIS PROCESS TAKES A WHILE for the first time. this alters the physics of an entire game that's optimized poorly.
I'm sure it has to do with how TS4 simulation is designed with this mod.. when I installed it my game also froze for a while well over 20-40 minutes before the loading screen went past the startup screen to get to the main screen. the logo version conflicts with the startup screen cause lag and The game has to read the mod, GUI, and the reshade. its alot on a processor for already poor simulation laggy games PLUS a visual shader mod to load with cc mods. so I think formation matters. but this only happened to me for that first time now it loads as it should. but this is how it looks upon loading most times my game runs smoothly at 8000MB which is high but again simulation is a big factor here for the stalling. 

 

make sure to only extract the d3d11.dll from the NEW zip file NOT the instructions in the old zip file. do not rename to reshade.dll or any of the other things as I have done this and my game did not launch. the new setup of reshade DOES work with Direct X11. move your original to a TEST folder or desktop then add the new one in its place. so you don't get confused . 

 

I am also running RESHADE 6.6.2 with ADDON SUPPORT. you can check which reshade you have hovering the dgxi.dll file if not uninstall reshade by clicking the reshade.exe, what do you wanna do? uninstall reshade ? click yes, download any version 5.5+

 

RESHADE UI AND RTBP UI LOOK JUST ALIKE make sure you change the position and settings for transparency and location for TS4 to have them both without issues. 

reason F8 opens GUI AND NOT F11 because F11 is default for landscape in TS4 and maximize mode for browsers on pc and will not work for the GUI. example:

 

when I used the logo version BUT I turn off the logo in the settings.ini file and turned startup logo to false . others have had issues installing and it was this simple fix for them. 

CPVC posted several versions in the thread logo and no-logo to help people with this AFTER the new version from Patreon in case they might help you

I'll list some of them here, but you can search the thread from this post onwards

 

 

 

 

 

 ive cleared my cache a few times as well (my local thumb cache) is there smth else to clear as well?

 

you should only have this RTBP folder. if you extracted the old RTBP one to the mods folder, DELETE IT that was with DX9 its old and not needed as CPVC explained HERE 

 

 

if you know how to manually clear cache use these folders click the .DAT file or exe dat usually runs through them all at once, don't do any of this if you are not sure how to (image 2 ) 

BUT if you use EA app you can clear your cache from there in the sims 4 settings if its like how Origin use to be 

 

also im rereading your message and u say it wont read with dx11, does this mean that it wont WORK with dx11, or that i did something wrong since im running it with dx11 theres a different set of instructions?

 

RIGHT you do not have to rename it for it to work, creators at Reshade are aware many TS4 players use this now, whereas before it was still new. so integrations have been made for direct 11 since TS4 was behind in Direct 9 for years, Reshade/gShade is ahead of TS4. its not necessary to rename the file for it to run with RTPB 

 

If none of the above helps this is how my BIN folder looks: try to replicate this format

Are you using shaders? You might be able to repair your game via the EA Launcher. Before doing that, you should back up your save game and mod folder. The next option, of course, would be to completely reinstall the game. I'm a bit surprised that some people are having these problems. Something seems to be different. I use 108 GB of mods and custom content, but it works for me. So something must have been changed in your game.

 

Did the RTBP versions work without a GUI?

Nope, No shaders. I do have over 235Gb in my mods folder. I did try with only RTBP and had the same results. Then I deleted the GUI folder and made some progress. I have to launch the TS4_DX9_x64 file. At the launch screen, I have to choose "load game" instead of resume. The game then loads75% of the time. It may crash out if I try to change worlds, go into build.buy mode or such. I like to drop to desktop while playing. While I can still do this, clicking back on game will crash it.

Yup, it's still a bit glitchy. I'm hoping it improves with time.

 

I'm currently working on a way to make it easier for users to report bugs and send their log files to me without having to go through Lover's Lab or something else. With more information, I should be able to deal with bugs and glitches more effectively.

Is it possible to make your mod appear in the Sim's radial menu? Click on the Sim, then click on RTP, and all the options for breast movement and possibly its settings appear.

People are used to the fact that mods for Sims 4 are always placed in the mods folder and can later be found by clicking the mouse button on the Sim. This will be easier for them. This would also solve another problem. People don’t understand whether this mod is installed or not. And if they see it in the game, then it is installed correctly.

P.S. I know this isn't actually a Sims 4 mod, but a DirectX setting.

P.S.S. How I see this mod working: Various interactions are bound to specific key combinations, and by pressing a virtual button in-game, we simply activate them.

Don't use fullscreen. In your document Documents\Electronic Arts\The Sims 4\Options.ini 

Change the value to (choose one, i use windowedfullscreen):

• Windowed fullscreen: fullscreen = 1, windowedfullscreen = 1
• Windowed: fullscreen = 0, windowedfullscreen = 0

hi could anyone pls guide me how to update this rtbp mod? after i update the patch game keep crashed when i opened it

[Gzbbbbbb]

Thank you for your update support, but there is a minor issue. After updating and using d3d11, I noticed that the thumbnails of characters in the game have errors. I'm not sure what's causing this. Is it just Log.txtme who has this issue, or is it happening to everyone
