📋 About This Mod
Xbox 1 version available on Bethesda.net.
This mod aims to give every Synth a unique look by using multiple retextures for every Synth armor piece, weapon and uniform (Courser included). This mod adds new Diffuse, Normal, Specular, Glow and Cube maps in 2k or 4k.
The difference between this mod and other Synth retextures, is that instead of only using one texture option, we make use of every retexture that we made. So instead of having only one armor set there are now 70 different armor sets in different colors, with different chrome and glow effects. This in combination with different Synths (full skin, some skin, skeleton) and having light, medium and heavy armor pieces every Synth will look unique.
Institute Synths: Synths found in the institute will use undamaged versions of the armor and wear uniforms.
Wasteland Synths: Synths found in the wasteland will use worn or damaged versions of the Synth armor.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Massive content drop: 191 new items total, so you'll never see the same Synth twice
- Community favorite with 16,183 endorsements and nearly a million downloads
- Both damaged and pristine looks mean you can have scavenged Synths and fresh-off-the-line ones
⚠️ Cons
- Last updated in 2018, so it might not play nice with newer DLC or mods that touch Synth gear

For Fallout 4 players who want more visual variety in their Synth encounters, especially those who love lore-friendly overhauls. If you're tired of seeing the same gray jumpsuits and want to make the Institute's forces look more diverse and battle-worn, this is for you. Skip if you want gameplay changes or new mechanics—this is purely cosmetic.
💡 Beginner Tips
- Since this mod edits vanilla armor, load it after any mod that changes Synth armor stats or appearance to ensure it takes effect
- If you use a mod manager, enable this mod and check for conflicts with other texture overhauls in the load order
- This mod doesn't require DLC, but if you have Far Harbor or Nuka-World, test for compatibility with their Synth variants
