Brax's Mystery Machine

Brax’s Mystery Machine (NSFW + SFW VERSIONS)

Hi sharks,

Are you down bad with the autism, and looking for a way to randomize variables in your COMFYUI prompts?

Well, I’ve got the tool for you!

I’m looking for a 0% stake in my company, for 1,000,000 dollars.

I’ve created a simple python script, called “Brax’s Mystery Machine” that loads variables from .txt files in the same directory as the script and attaches them to a prompt that is well built for most AI image / video generators.

I know wildcards exist, and other add-ons for comfyui, but I always seem to have difficulty transitioning to another type of pose / scenario for the character.

The current script serves as a bridge to help randomize attributes of a character (female) in different prompts. It can also be a good bridge for folks that aren’t using COMFYUI

Here’s some things that this script currently randomizes:

Hair (type and color)

Skin Color

Body Type

Breast Size

Eye color

facial expression

makeup

Clothing (type and color) (The script can handle tops and bottoms)

stockings / leggings

shoes (type and color)

Makeup

Jewelry

Nipple piercings (I find that nipple piercings while wearing any top makes images come out weird, so I made this setting only work if the character is topless or is lifting their top in the prompt)

Glasses

Facial expressions

Pose / Scenario that the character is in

Here are some other add-ons that can be toggled in app manually:

Long sleeve - only pulled from tops/long_sleeve_tops.txt

Short sleeve - only pulls from tops/short_sleeve_tops.txt

Sweaters - only pulls from tops/sweaters.txt

Bras - only pulls from tops/bras.txt

Pants - only pulls from bottoms/pants.txt

shorts - only pulls from bottoms/shorts.txt

Skirts - only pulls from bottoms/skirts.txt

panties - only pulls from bottoms/panties.txt

No top (removes top type / color and replaces this with: No top, Breasts exposed, Nipples exposed)

No bottoms (removes bottom type / color and replaces this with: no bottoms, crotch exposed, pussy exposed)

No shoes (removes shoe type / color and replaces this with: no shoes, bare feet exposed)

No Nipple Piercings - disables the item from being pulled into the script

No Glasses - disables the item from being pulled into the script

No Makeup - disables the item from being pulled into the script

No Stockings - disables the item from being pulled into the script

No jewelry - disables the item from being pulled into the script

No expression - disables the item from being pulled into the script

Don’t like a current item that’s in the mix? Remove it from the .txt file! Want more options? Add them to the .txt file!

Have a lora you’d like to add in to a prompt / item? Add it to the respective .txt file, and it’ll always get created. I didn’t add any items / poses with lora’s, as I would hate for you to have to download a bunch of stuff you might not use.

EXAMPLE: Lifting her top, blushing, looking away from viewer, lora:cfg\_scale\_boost\_854525:0.5 | top lift | glasses |

Find a certain item / color that makes you go “WOW!”? Lock it by clicking on the title for that item, it will turn red and be immune to randomizing!

Each one of the .txt files are where variables are stored, follow this formatting when adding / removing items and scenarios:

1

2

3

Apple

Banana

Horse

ETC….

I spent a lot of (autistic) energy on the way that poses / scenarios are handled from the pose.txt file in the main.py logic.

Essentially, you can hardcode different modifiers for the character at the end of a pose / scenario so that it’s always handled that way.

Here’s the modifiers:

Topless

Bottomless

Shoeless

Nude

Top Lift

No Makeup

no jewelry

No Nipple piercings

No Stockings

no expression

no glasses

With any of these predefined in your pose / scenario, it will act the same as manually clicking the checkbox in app.

You can have multiple modifiers running on a pose / scenario at the same time, you just need to format them with a break symbol at the end of your prompts, IE:

Sitting on a couch, legs spread, looking away from viewer | top lift | bottomless | shoeless

I have also created pose categories, as I was getting lost trying to find certain prompts that were in the pose.txt file.

There are some categories built out already, and you can create new ones by using [category name here], at the top of a said category in pose.txt

Here’s the categories that I’ve already built out:

[ALL] (Built in) (This will show all poses / scenarios for pose.txt, no matter the category)

[MASTURBATION]

[FLASHING]

[POSE]

[AFTER SEX]

[BLOWJOB]

[MISSIONARY]

[DOGGY]

[HANDJOB]

[COWGIRL]

The default start of any prompt piece is as follows:

"score_9, score_8_up, score_7_up, masterpiece, best quality, newest, absurdes, pixelsketcher, very awa, newest, 1 woman"

You can modify the main.py file so the start of your prompts will look how you’d like.

Not a big NSFW person? No Problem! I’ve created a different version of this app that doesn’t have that stuff in it!

Requirements / usage:

Python 3.10+

https://www.python.org/ftp/python/3.13.5/python-3.13.5-amd64.exe

PYPERCLIP

open command prompt, after python is installed, and run:

pip install pyperclip

After these two, just double click the .bat file and the program should launch!

If you have any issues getting this to launch though, please let me know.

All in all, I know this creation is a lot (super autistic), and I accept that, but I like when I can randomize things, and this… helps my sanity when I build images / videos.

Got a question, suggestion, or just want to call me autisic AF? Bleep Bloop it down in the comments, and I’ll read / answer accordingly.

I’m always down for looking at your creations! If you’ve modified a .txt file or the entire script, send it my way, and I’ll be sure to shout you out and post a link to your creation!

Post your created media at the bottom of this page! I’d love to see whatever you can make!

I will never monetize this package, or will ever reach out to you for any kind of monetary values, please be careful when talking to strangers gamers! If you take this package and try to sell it, I will blow your house up and subscribe your phone number to a bunch of scammer call centers.

Nonetheless, have fun my discord kittens, and let me know if you need anything.

V2.0 - changelog - 7/26/2025

Added glasses as a modifiable attribute in: glasses/glasses.txt

Added jewelry as a new item with its own .txt file: jewelry/jewelry.txt

Added makeup as a new item with its own .txt file: makeup/makeup.txt

Stockings automatically disable from the prompt if the item is from bottoms/pants.txt

If a pose has a modifier it will turn that variable red and erase the text, to eliminate confusion.

new overrides:

long sleeve - only pulls from tops/long_sleeve_tops.txt

short sleeve - only pulls from tops/short_sleeve_tops.txt

sweaters - only pulls from tops/sweaters.txt

bras - only pulls from tops/bras.txt

pants - only pulls from bottoms/pants.txt

shorts - only pulls from bottoms/shorts.txt

skirts - only pulls from bottoms/skirts.txt

panties - only pulls from bottoms/panties.txt

Adding better prompting so images come out more slick.

combined colors for clothing, hair and skin still separated.

I recommend adding items to the .txt files like this: satin_skirt

The final output will look like: (purple_colored_satin_skirt:1.0)

Because the new formatting has so many items crammed into the prompt, I recommend turning CFG down a little, so the VAE and Model adhere to the prompt better.

Added a setting button in the top left to change the background color in the GUI

If you ever have a question, suggestion, or want to quote the bee movie, shoot it down in the comments so I can see it!

Love this project and community! Thanks again for the support!
