📋 About This Mod
I replaced Gen 1's, 2's and Nick Valentine with Warfighter's IW - Synaptic armor. It does not touch Gen 3's or Coursers. Because some clipped through I also replaced their meshes with a scaled down (to practical invisibility) grenade pin mesh. The mesh though unrecognizable was from a VOG17 grenade. I no longer see the mod on here but I removed almost the entire mesh and rescaled the bit left. If anyone knows who the author was please message so I can get in contact with them and properly credit them.
If you are having issues with the mod that adds Valentine back to normal this mod fixes those issues according to other posts: Valentine Reborn

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved with 286 endorsements
- Over 12,000 downloads shows real demand
- Touches both generic synths and a major companion
⚠️ Cons
- Last updated in 2021, so may not be compatible with newer mods or game updates
- Only affects Gen 1 and Gen 2 synths, not Gen 3 or other synth variants
- Potential conflicts with other mods that alter synth armor or Nick Valentine
For Fallout 4 players who want a visual refresh for the older synth models and a new look for Nick Valentine. If you're tired of the default synth armor and want something different without gameplay changes, this is for you. Skip if you're looking for gameplay tweaks or if you use other mods that overhaul the same assets.
💡 Beginner Tips
- Since it's a mesh/armor replacer, load order matters less, but place it after other mods that change synth armor to ensure it takes effect.
- If you use a mod manager like Vortex or MO2, let it handle the file conflicts to avoid overwriting issues.
- Check the mod page for any optional files or patches that might be needed for compatibility with other popular mods.
