Synthetic Variations

Adding some variety to the Synths of the Commonwealth

Thanks to everyone for your support, downloads and endorsements, especially those that have commented. Your suggestions, questions and and support have been one of the real highlight of this experience.

I really hope you enjoy the updated version.

Version 2 Updates:

Added varied Male/Female Coursers to level lists with a new outfit for them.

Changed Encounter zones so new Synths will appear in places like Fort Hagen and Arc Jet.

Optional Lite Version - All the new synths in a Zip file under 6MB.

Optional Low Level Add-on - New Synths now appear at lower levels as well.

Optional CAST Synthetic Overhaul Add-on - Not a Patch CAST is already compatible without one, it just makes the changes made by CAST appear more often.

Fixed some meshes, Skirts and dresses should move correctly now.

Outfits now craftable in Basic low stats versions and original mod stat versions.

Changed the robotic limbs on Gen2X class to the Mech version to improve compatibility with Terminator mods

Edited the Synth Rear Head model so that Wigs fit better without causing bald spots.

Lots of optional Mesh replaces to Tailor which outfits etc you want in the game.

Corrected spelling of Exercutioner to executioner (thanks MarrockV)

(More detailed information can be found in the relevant sections of the description below)

As I've changed pretty much every mesh as well as massively changed the original esp I would probably advise uninstalling the old mod and downloading anew if you want to upgrade.

I don't think you 'have to' as I don't touch scripts, quests or stuff like that but it may help***

Also please don't update to a save during the middle of a Synth battle or mission. I don't know loads about modding but I'm pretty sure that would be a bad idea.

Future Update

I don't plan on updating this again for a while as I really want to continue with my other projects Primarily I am already part way through a Super Mutant variation mod 'The Mutant Masses' and a as yet un-named Gunners variation mod. I will of course make any updates involving fixes (hopefully there aren't any)

When I do update though these are the things I hope to add:

Settlers add-on - Unlockable beacons that attract Synth Settlers

Optional voices for the new Synths

Compatibility with some of the other female Gen2 Mods

Missions Add-on - Create missions involving the new synths

💡 Beginner Tips

  • Since the mod adds new NPCs, make sure you have the necessary DLCs installed (like Automatron) if the mod requires them — check the mod page for details.
  • If you're using a mod manager like Vortex or NMM, install the mod through it to avoid manual file placement issues.
  • Load order shouldn't matter much for this mod, but placing it near other NPC mods can help avoid conflicts.
