What Are .ytd Files?

YTD stands for Y Texture Dictionary — it's GTA V's format for storing texture data. Every vehicle, building, prop, and character in GTA V uses .ytd files for their visual appearance.

When you install modded vehicles on a FiveM server, the .ytd files are often the biggest files in the resource, sometimes 10-50 MB each. This is because many mod authors include unnecessarily high-resolution textures.

Why Optimize Textures?

The Problem

A typical modded vehicle might include textures at 4096x4096 resolution. At that size:

A single vehicle's textures can be 20-50 MB

50 vehicles = 1-2.5 GB just in textures

Players experience long loading times and texture pop-in

Servers use more bandwidth streaming these files

The Reality

In-game, most vehicle textures are viewed from a distance where 4096x4096 and 1024x1024 look identical. Even up close, 2048x2048 is more than enough for most surfaces. The extra resolution is wasted data.

Method 1: Glory Optimizer (Recommended)

Glory Optimizer is purpose-built for optimizing .ytd files. It handles the entire process automatically:

How to Use It

Download and install: Glory Optimizer (Windows desktop app)

Select your Textures Folder: — the folder containing .ytd files

Set a Backup Folder: (optional but recommended) — your originals will be copied here first

Set the Optimize Size: — this is the threshold in pixels. Textures where Width + Height >= this value will be downsized. Default is 1024.

Click Optimize: and wait for it to finish

Check the Before/After stats: — you'll see exactly how much space was saved

Choosing the Right Optimize Size

4096: — Very conservative. Only downsizes the largest textures. Minimal visual change.

2048: — Good balance. Catches most oversized textures.

1024: — Recommended default. Significantly reduces sizes with no noticeable quality loss in-game.

512: — Aggressive. Use for maximum size reduction, but some textures may look slightly softer up close.

Typical Results

Vehicle textures: 50-70% size reduction

Total folder with 50+ .ytd files: 40-60% smaller

Visual quality in-game: No noticeable difference at 1024 threshold

Method 2: Manual Optimization (Hard Way)

If you want to optimize textures manually, here's the process:

Tools Needed

OpenIV: — to open and edit .ytd files

Image editor: (Photoshop, GIMP) — to resize textures

DirectX texture tools: — to re-compress as DDS

Manual Steps

Open the .ytd file in OpenIV

Export each texture as .dds or .png

Resize in your image editor (e.g., 4096x4096 → 1024x1024)

Re-compress as DDS with DXT1 (no alpha) or DXT5 (with alpha)

Import back into the .ytd

Save and test

This takes 5-15 minutes per texture. A single vehicle can have 10-30 textures. For a whole server, this would take days.

Best Practices

Always Keep Backups

Before optimizing any textures, back up your originals. Glory Optimizer has a built-in backup option — use it.

Test After Optimizing

After optimization, load your server and check vehicles visually:

Do textures look acceptable from normal gameplay distance?

Are any textures obviously blurry or broken?

Do liveries and text still look readable?

Optimize in Batches

Don't optimize your entire server at once. Do it in batches:

Start with the largest .ytd files first (biggest size savings)

Test after each batch

If something looks wrong, restore from backup and try a higher threshold

Skip Small Files

Files under 2 MB are already small enough. Focus optimization efforts on files over 5-10 MB where you'll see the most savings.

When NOT to Optimize

Livery textures: with fine text or logos — these can become unreadable at lower resolutions

UI/HUD textures: — these need to be pixel-perfect

Map textures: viewed up close — building facades, signs, etc.

For vehicle body textures, paint, and material details? Optimize away — the savings are worth it.
