The back of Super Mutant heads aren't loading in for me

[Barrett]

I did the mission to get Strong yesterday and every Super Mutant there, including Strong, don't have the back of their heads. Every other part of their bodies are there, just not the back of their head. I believe I was using the Super Mutant Redux mod a bit ago and replaced it with the Organic Super Mutants mod and I think that's why this is happening. Anyone know how I can fix this without having to do a complete restart?

Changing/removing mods that potentially use scripts midgame is the worst idea you can have with bethesdas engine.

If the previous mod got really removed completly (and not some remains in mesh-sub-folders are left) you might have luck that the supermutants turn back normal when the cells reset. But no guarantee on that.

Changing non-scripted mods works more reliable when done while the player is in an inside zone where the world scripts are not running - the sanctuary bunker behind the house for example.

Whenever you remove a mod and or mixed in another midgame, it still stays kinda baked into your Save. You could try reinstalling Organic Super mutants again in the hope of fixing the head issue, or even doing without organic and putting Super Mutant redux back, but this will probably cause even more issues. You could try going back to a Save before you installed these Mods and try again.

Personally I'd bite the bullet and start fresh with the Organic Mutant mod and any other mod you like and never uninstall or replace them while you play a campaign.

This is a known issue with Super Mutant Redux. And has been reported multiple times but the mod author simply refuses to acknowledge the bug, or fix it. (Hence why SMR is not a popular mod anymore)

Your problem is 2 fold:

SMR replaced the super mutant textures for super mutants and the back of the head is missing from his textures.... Those textures either
A: Did not uninstall properly -most likely as they were packed as loose files, and are still in your system (possible depending on mod manager used, method used to uninstall, etc)

B: Baked the texture files into your savegame array, and now no longer load in the back of the head texture.

Unfortunately there is no solution hat you will like.

THE SAFEST WAY:
Remove Both Mods from your mod manager completely. Reload the one your want and start a NEW game.

UNSAFE WAY:
make sure both mods are fully removed from the mod manager, then re-install the one you want.
