@twelvemidnight12 Let me try again, Regarding 'not working': My engine supports standard http, https, absolute local paths C:\, and file:/// URIs. If you see a blank screen, it is a syntax error in your URL or a port conflict on your local host. Ensure ShowOnStart is true in your INI or you won't see anything until you hit the toggle key.

@ShadowOne did that
same issue

@ShadowOne good luck with your project.

@lelac14 I apologize for the harsh tone in my last reply. I’ve been under a lot of pressure balancing this project with my engineering exams. I appreciate you being here since the start, even when we didn't see eye-to-eye. I’ve pushed some stability fixes for the display resets, and I hope they work better for you. Take care.

Looking good!

oh wow this is a really cool project

Why is it stuttering when running a web page in full screen?

I tried creating my own, but it seems that it couldnt establish connection between the game in my HTML Files

Hello ShadowOne! 👋

First of all, thank you very much for your amazing work and for creating these tools for GTA V. I really appreciate your effort! 🙏❤️

I have my own HTML file that I designed, and I would like to display and run it inside GTA V Story Mode while also being able to show and use the mouse cursor.

However, I’m a little confused about the installation process. I don’t know exactly how to organize the files, where I should place my HTML file, or which version I need to download for my GTA V version.

Could you please help me understand the correct way to set everything up? I would be very grateful for your help. Thank you again for your great work! 🙏😊

@silentzer14 I have a similar problem; has a solution been found?

@aboahmad No Solution brother

@silentzer14 Thanks, brother, but it just doesn’t make sense to me that there’s no way to display an HTML interface in GTA V and interact with it using the mouse. I’m trying to find a way to make it work.

@lelac14 Have you found a way to run HTML on GTA 5?

The last update was in June. When will the next one be?

@ShadowOne I was able to open the webpage successfully, but I couldn't play the video. The error message said: "It is suggested that your current browser does not support the HTML5 player."

@ShadowOne If it were possible to render web pages on the entity TV screen within the game, that would be even better. It would be a historic change in the offline mod history.

@DanJaLey Hello mate, the project development is currently suspended due to my potato laptop and my studies. I won't be able to continue working on it until the end of June 2027. The C# api contains some non-wroking functions and you may encounter some bugs regarding the layers if you spawned multiple pages on top of each other. About the HTML5 support, CEF should support the latest HTML, CSS and JS. I'm not really sure why it's showing that error, it could be due to my outadated CEF core distribution I'm currently using with this project. About the ability to render web pages on entity TV screen within the game, it is possible and i actually did it, i played an mp4 on a screen I spawned in game with a custom encoder from mp4 to pixel buffer which get passed to the game through DirectX hooking, I was supposed to write an SDK and publish it online so you can guys use it whatever you want like playing Youtube videos, Twitch streams, run emulators for games like Doom and other retro games ( the emulator needs to have headless compatibility) and even Linux or Windows ( also require a headless VM ) but a lot of important things happened distracting me a way from modding. If i got time I'll try working on the sdk with some documentaion, it's not a promise but I'll try, thanks for trying WebUI.

@ShadowOne Thanks so much for the detailed reply, it really means a lot. I totally get it — studies have to come first, and modding on a potato laptop is such a pain, no rush at all, take all the time you need.
I have to say, that custom encoder → pixel buffer → DirectX hook setup you did for rendering onto entity screens is genuinely groundbreaking for GTA V. Right now all we have is MediaPlayerV for straight video playback on TVs, but there’s nothing that can render full web pages, browse sites natively, or run headless emulators and VMs on in‑game screens. That SDK you were working on would open up so many possibilities — people would build all kinds of crazy stuff with it.
If you ever get back to this project down the line, please know the community is ready to help lift the workload off you. A bunch of us would happily test pre‑release builds, triage and document bugs, write user tutorials, or even test and repackage newer CEF versions so you don’t have to mess with that on your laptop. You could focus 100% on the core SDK code and we’d handle the rest.
No pressure at all though. Focus on your studies and we’ll be here whenever you’re ready. Thanks again for making WebUI — it’s already such a cool mod even in its current state.

@DanJaLey Hey, I'll be glad to open source WebUI and the RTI (Runtime Texture Injector) SDK on GitHub, but it will take some time due to my messy workspace. I can't currently upload anything because the project's folder size is over 25 Gigs, filled with backups, compiled binaries, SDKs, old Ultralight versions, and VS cache.
The only thing I can probably do right now is take my time cleaning out RTI and writing some documentation, so maybe by the end of next week, it will be available on GitHub. This is not a promise that it'll be ready by then, nor is it a guarantee of perfection. Its general purpose is to identify and swap textures during runtime using specific details like the hash, which will allow other devs to create things like working TVs, billboards, and more.
Thank you for your passion for my work.

@ShadowOne That’s absolutely incredible news — thank you so much for being willing to open source both WebUI and the RTI SDK. This is genuinely huge for the entire GTA V modding scene.
I totally get how much of a headache cleaning up a 25GB project folder full of old builds, backups, cache and legacy versions is. Take all the time you need, there’s absolutely zero rush.
The RTI runtime texture injection approach is such a game-changing foundation. Once it’s public, modders are going to be able to build all kinds of stuff we’ve never really had properly before — perfectly locked in‑game browser screens, dynamic billboards, custom video displays, you name it. It’s going to open up so many possibilities.
If you need an extra hand with testing, drafting documentation, or anything else to take a bit of weight off once you’re further along, just say the word.
Really appreciate you putting in the work on this, man. We’ll all be here whenever it’s ready.
