Is there a method/tool for editing custom sliders? I'm not looking to change the actual function, I just want to edit the labels and the region they are located at in CAS.

I wonder this too!

I edit both the labels and the panels they appear on all the time! You can edit the prompts/labels using the S3 STBL editor (s3se) .


In the above image-
1) Select the source/target language you want to change.
2) Click on one of the lines in the grid. ("MOST" sliders will only have 1)
3) Edit the text in the text box to whatever you want. Keep it "short-ish". If you put a * in front like I did, your custom sliders will appear at the top of the list in game.
4) Hit the commit button, or else it won't stick.
5) If you only want to change your language, clike 'Target 1', or if you want to copy to all languages (it won't translate it, mind you) click 'All 2'.
6) (not numbered in the picture. SAVE!

To change which panel they show up on, you use S3 Package Editor (s3pe). (You can edit the labels with this tool too, but it's a little more tedious.)

To place the sliders in CAS subpanels (nose tip, etc.);

Open the package in s3pe,
Find/Select the FBLN resource (Type 0xB52F5055) (1) and click Grid (2). Look in the data grid for the "CASPanelGroup" (3) and "Sort" (4) value, and change them using the following values:

EDIT: I attached a screen capture to show the areas in S3PE to edit, and numbered accordingly.

HUMANS:

For humans, the CASPanelGroup is obviously named, so pick it from the list. Change the sort based on the following:

Head and Ears:
Global = 0x00000001
Cheek = 0x00000010
Chin = 0x00000020
Ear = 0x00000040
Jaw = 0x00000400

Mouth:
Global = 0x00000002
Lower Lip = 0x00000800
Upper Lip = 0x00008000

Nose:
Global = 0x00000002
Bridge = 0x00000004
Nostrils = 0x00001000
Nose Tip = 0x00004000

Eyes:
Global = 0x00000002
Brows = 0x00000008
Eyelid = 0x00000080
Eye Shape = 0x00000100

Eyelashes:
Length = 0x00000002

PETS:

Unlike Humans, the CASPanelGroup values for pets are less intuitive:

CASPanelGroup:
0x00000001 = Cheek
0x00000002 = Head
0x00000008 = Muzzle
0x00000010 = Nose
0x00000020 = Ears for Horses, Cats, and for Dogs when using Sort 0x00100000
0x00000080 = Eyes
0x00000200 = Body
0x00000400 = Legs (Does not appear for cats)
0x00001000 = Ears for big Dogs when using Sort 0x00040000 and for Little Dogs when using Sort 0x00080000 (I'm not completely sure about this.)

Sort:
0x00010000 = Horses
0x00020000 = Cats
0x00040000 = Dogs (big)
0x00080000 = Little Dogs
0x00100000 = Cats and all Dogs

NOTE : I did not come up with the knowledge. I picked it up somewhere a few years ago but sadly I don't know where or from whom. Sorry!

What I would like to know is can you turn them off for random sims? I know some sliders do affect random sims, but others do not. I would *really* like to turn them all off.

You are a wizard. Thank you

Thank you so much for this! On the hopes you're still lurking around, did you ever find out how to turn them all off for random sims?

Yep, still lurking. But sadly, no, I never did find out any information on how to turn sliders off for random.

@roddyaleixo @k2m1too

A slider can be disabled for the randomisation button (where most see sliders get up to no good) by changing the FacialRegion on the FACE resources to all zeroes.
In S3PE Grid edit, CASEntries > drop down each entry > change their FacialRegion to 0x00000000.

Note, however, that this isn't related to whether a randomly generated sim will use the slider.
Townies aren't randomised, they're spawned from genetics- either from generic template sims, or even from sims who are saved in the household bin. You typically don't have to worry about them using custom sliders because of this- but they can still inherit them if the sim whose genetics they're borrowing used them. You can use NRaas StoryProgression to disallow specific bin households from being used in this way, if you have sims whose custom slider use doesn't make sense to include in the gene pool.

Confirmed and tested by comparing Cmar and Bloom's height sliders to find why the latter doesn't budge when randomised, changing the FacialRegion so that both sliders didn't change, and then using Play With Genetics to create offspring that still inherited height.

This is AMAZING! Your are AMAZING! Thank you so much for this! I am off to edit my myriad of slider files now LOL!

EDIT:
I’m happy to report that after adjusting all my body sliders, everything worked perfectly! I do have over 200 face sliders though, but I’m satisfied with the current face randomization and don’t feel the need to tweak those files. Even better, none of the changes I made to the files affected my pre-existing sims. I tested this by creating some quirky sims beforehand and saving them to the bin before modifying the files to make sure the changes would stick, and they did! This is a total game changer. Thank you once again.

I’ve been using this thread to help me edit my own collection of sliders and since the thread is relevant again I decided I would add a couple of things that helped me while I’ve ran into some blocks and made mistakes.

First I made a mistake reading your help by ignoring where you said edit the sort number - where in editing the FBLN resource I mixed up the CASPanelGroup number and the Sort number- which I previously thought was not important at all… WRONG

For clarification for anyone who messed this up too, TRUST what the CASPanelGroup says and click on whatever category you want the slider to show up in IN that, but directly UNDER is the *sort* category which is where you edit using the list of numbers from before. It’s a silly mistake to make, but if I made it I’m sure some others have as well.

Another issue I ran into is I couldn’t get access to the STBL editor linked so I figured out how to do so in s3pe-not difficult to find how, but I’m sure it will be convenient for someone to have it all in one thread

Find the STBL resource and right click- and than click edit STBL, you can edit this in the panel on the right!! Just click save and confirm and save in S3PE again and your done!!

That’s all I wanted to add!! This thread has been beyond useful for me, so I wanted to help too! I’m excited about the prospect of removing the randomization aspect! I’ll probably get to that soon as well, though it’s been tedious already so I might take a break. Thanks everyone! My first post or reply ever on this site btw! Yippee

That's super helpful. Now I can make the head size slider stop randomly generating bobble/shrunken heads (though I have to admit it is sometimes quite amusing).

Also for anyone needing more wordy descriptions of how to make the changes I do have tip-torials on my tumblr - Slider Labels and Slider Categorization

I tend to have problems with wordy. A picture with arrows and little captions (like, "HERE be dragon")... now THOSE I can follow! :D
