Modify a .ytd file in GTA V

1) Prepare the environment

• Download and install OpenIV (if not already done).
• Make sure your mods folder is properly configured in OpenIV (ASI Manager → “Install OpenIV.ASI” and “Enable mods folder”).
• Activate "Edit Mode" at the top right of the OpenIV window.

2) Locate the .ytd file you want

• In OpenIV, navigate to: mods\update\update.rpf\x64\data\cdimages\scaleform_generic.rpf\
• Find the file loadingscreen_startup.ytd (make sure you are in the mods folder).

3) Export textures to PNG

• Double-click on loadingscreen_startup.ytd → The Texture Viewer opens: it displays all the textures contained.
• Select one or more textures (e.g., beach_bg or beach_fg).
• Click on “Export all textures” or “Export Selected” → “Export as PNG” and choose a folder (e.g., D:\GTA_V\textures\).
• Repeat for each texture you want to modify.

4) Modify the images

• Open the exported PNGs in Photoshop (or GIMP, Paint.NET…).
• Modify them according to your needs (change a logo, add an image, etc.).
• Warning: do not change the dimensions of the image, keep exactly the same resolution.
• Save as 24-bit or 32-bit PNG (if you want to keep transparency).
• The file names must remain identical to the originals (e.g., beach_bg.png).

5) Re-inject the modified textures into the .ytd

Quick method (Replace)

• Go back to OpenIV → reopen loadingscreen_startup.ytd.
• Click on “Replace”.
• Select your modified PNG → OpenIV will replace the texture inside the .ytd.
• Save by clicking on “Save”.

Advanced method (new .ytd)

• In OpenIV: Tools > Texture Dictionary > New.
• Name: loadingscreen_startup.ytd.
• Click on “Add” → import all your modified PNGs.
• Save with “Save”.
• In scaleform_generic.rpf, right-click on the .ytd → “Replace” → choose your new file.

6) Test in-game

• Launch GTA V (single player).
• Look at the loading screen → the first image should appear modified!

7) Tips & precautions

• Always make a backup of the original file before replacement.
• First test with a single modified texture.
• Always respect the dimensions and formats of the original PNGs.
• If the screen remains black or crashes → restore the original and check the dimensions.

And that's it! With this method, you can modify any .ytd of the game: not only loading screens, but also phone icons, vehicle textures, weapons, clothing, etc.
