Sims 4 CC hair works in CAS but switches to bald in-game

@gpnphwpd7d2s 

This is a guess but from what you describe, the mesh for the hair is probably missing.  You probably downloaded a separate recolor of the hair.  So, you might want to go back to where you got the CC and see if the mesh file is a separate download and you didn't download it or if there is a link or at least a statement about where you can get the mesh.  

Hope this helps.

Thanks for the reply!

I thought that might be the case, but from what I know, if the mesh was missing, the hair wouldn't show up in CAS at all, right?

They look great in CAS, the hair doesn't show up as bald. The hair choice for the sim switches to the base game bald hair hairstyle whenever I save sim in CAS and go to gameplay. Could this still be the missing mesh?

Edit: I've just checked the hair I've downloaded and those were not recolors, they included meshes :/

Well, yeah, you're right and that takes care of the obvious :D.  What can I say, it was late, I was tired, and I just missed it.  Duh!  So..... New day, I'm awake and thinking again.

Most likely, it might be something else in your mods folder could be interfering with it in live mode.  The easy way to check is to rename your current The Sims 4 folder and start the game to let it generate a new one.  Then after making and placing the sim.  Save and exit.  Then put the hair that is causing the problem in the new game's mod folder by itself and restart the game.  Put the hair on a sim and go to live mode to see if shows up.  If it doesn't, it's the hair.  If it does, it has to be something else in your mods folder interfering with it.  CC 3D eyelashes, earrings, tattoos, piercings would be the first things I would check as possible causes.  A while back, I had a CC tattoo, that after one of the updates, still looked great in CAS but in live mode it turned the sims it was on completely black.  It took me a while to figure out it was a tattoo doing that.  Once I found and removed it, the sims were back to normal.  You might have something similar going on and if that is the case, you're going to have to go through you CC to find the troublemaker.  

If that doesn't work to get the hair to display properly, another thing it could be is that it is old and predates the additional color swatches that were added a while ago.  To check that, take a look to see if it has the same number of color swatches that game hairs do just to make sure it was made since the update that added the extra colors.  You can also take a look what happens when you click the match hair button on the eyebrows to see if the colors match too. If it's a male hair, you can also do that with facial hair.  Another way is to switch hairstyles in CAS back and forth with a game hair to see if the hair shows the same color as a game hair for each swatch.  A lot of them don't though but work perfectly fine but what you're checking for is that each swatch gets used.  It could be that the creator didn't use one and live mode is grabbing that unused swatch for some reason rather than the color you chose.  Long shot really but I've seen stranger things happen with CC.

If none of that works, come back and let me know and we'll go from there.

Hope this helps.

Woow, thanks so much for such a detailed answer! I really appreciate your time <3

So I was trying out all the things you suggested and none semeed to work. But then after restarting the game I noticed that I had an overdue update. I installed and restarted the game, then switched mods back on and restarted again and it solved the issue. I have NO idea what happened here but all the CC hair works fine now and doesn't switch in-game anymore. So yeah, if anyone ever has a similar problem just check for updates, I think it repaired some faulty game files maybe.

Thanks for your help again! 🙂
