VN Ren'Py Atlas Bay: Babylon [Development Thread]

[FROMSPACE]

Hey everyone! h4xx FROMSPACE team here, new to AVN game dev and excited to share our first project: Atlas Bay: Babylon.

We are aiming for an immersive experience with a mix of erotica, intrigue, and a world full of unique characters and hidden agendas. Right now, it’s being built in RenPy with AI tools for sounds, music, images, and animations.

This post is just a quick intro. More details and some early CGs will be posted in our Patreon:

# About Atlas Bay: Babylon

Atlas Bay: Babylon takes place in Atlas Bay, a city built on luxury, secrets, and temptation.

You play as Leo, a 28-year-old multimillionaire who built his wealth through early cryptocurrency investments and high-risk financial ventures. Looking for a new beginning, Leo moves into Babylon, an exclusive high-rise owned and inhabited by the city’s elite.

Life inside Babylon sparkles with glamorous neighbors, high-profile parties, and hidden agendas. Beneath the surface, a powerful criminal network shapes the city from the shadows. At its center is Mateo Fernández, the building’s revered and feared penthouse resident.

As Leo settles in, he’s drawn into a world where desire and danger constantly collide. Your choices guide his relationships, uncover secrets, and determine how deeply he becomes tied to the darker side of Atlas Bay.

The Atlas Bay Universe

Atlas Bay isn’t a one-and-done story. It’s a world.
Future projects will explore new characters, new perspectives, and new formats within the same universe. Babylon is only the beginning.

Good luck with your project. Are you planning to release an android version?

Good luck with your project. Are you planning to release an android version?

Hey, yes, it is planned to have an Android version, not for the first public release (Chapter 1) but for the follow-up version.

I will add a section with the expected platforms and features. Thank you.

Quick update to present our MC (Leo)



Leo (Name can be changed)

A young multi-millionaire who’s just moved into Apartment A on the 16th floor of Babylon, renting the apartment from Doña Dolores. Leo made his fortune early by investing in Bitcoin and diving into high-stakes financial ventures, which opened doors to Atlas Bay’s elite circles. These days, he works as an independent investor and consultant, advising startups and managing a diverse portfolio. Despite his wealth, Leo is searching for excitement, purpose, and real connections in the city. Smart and ambitious, he’s naturally drawn to the mysteries and temptations of Babylon, where every encounter could change his future. As the protagonist, Leo finds himself navigating glamorous parties, complicated relationships, and the hidden dangers that lurk beneath the city’s luxurious surface.

# Development notes
From a development perspective, I created a LoRA for the character to ensure consistency remains above 70% (my acceptance threshold for this AVN). While it works for now, for Chapter 2, I plan to either retrain the LoRA or fine-tune the base model to improve flexibility while maintaining consistency.

This time two character description... Valerie Summers and her husband Nathan Summers



Valerie Summers

Friendly neighbor, lives in Apartment B on the 16th floor with her husband Nathan, known for her warmth and kindness. Valerie is elegant, approachable, and always ready to help a neighbor in need. She has a talent for making people feel at home and is quick to offer support or a listening ear. Her easy laughter and genuine smile make her popular among residents, but she values her privacy and prefers quiet evenings over wild parties. Despite her gentle nature, Valerie is perceptive and not easily fooled by appearances, making her a trusted confidante for those who earn her respect. Her relationship with Nathan is caring but often distant, as he is frequently away for work, leaving Valerie to manage much of her life independently. She remains loyal and supportive, but sometimes wonders what she truly wants from her future.




Nathan Summers

Valerie's husband, lives in Apartment B on the 16th floor, reserved and private. Nathan is a successful professional whose demanding career keeps him away from home for long stretches. He is quiet, introspective, and prefers to keep his personal life out of the spotlight. While he cares deeply for Valerie, his frequent absences and focus on work have created a sense of distance in their marriage. Nathan values stability and routine, and is more comfortable with quiet evenings than the lively social scene of Babylon. He is loyal and dependable, but sometimes struggles to express his emotions, making him a bit of a mystery even to those closest to him.

# Development notes
These two characters don’t have a trained LoRA, their consistency is achieved through careful prompting and inpainting details.

I'm not dead! Just a lot of work these past weeks. First things first, I want to redo my style of Dev Logs, the idea is to post weekly updates here on F95 with less detail and more general, small, and random updates via

. Detailed logs will go on Patron (just an idea.. atm, there is no Patreon).

So without delaying further, here comes:

Development Log #3

Characters
I’ve developed 11 characters with their own images and stories. A last-minute addition was Lucia Fernandez, Mateo’s daughter, to make things more interesting for the future.



To recap: Leo (MC), Nathan and Valerie Summers, Ramón Gutierrez, Mateo, Olivia and Lucia Fernandez, Felicity (remote assistant), Sabrina Jackson (Famous Singer), Izzy (Bartender), and Marco Rossi (Famous DJ). I’ve left around 9 more characters for Chapter 1.


Story
Initially, I wanted a kinetic story without branching paths, but during my latest script brainstorming sessions, I realized there’s potential in adding choices that affect how the MC talks, behaves, and interacts with others. So I’m happy to announce that Atlas Bay: Babylon will have branching paths and decisions that influence character relationships.



Due to these changes, I’ve adjusted the script completion percentage from 50% to around 30%. The good news is that I have the main storylines defined, which will speed up the process.


CGs
I’ve generated a ton of CGs, from 17 in the last update to 50 now. I also plan to split some into more detailed versions. For example, when the MC first enters Babylon, there’s a party going on. Right now, the CG is a general shot of the entrance, but I’m working on more focused versions for each interesting group of people there.



Music
I’m really excited about the music. I’ve been experimenting with different AI music and sound effect generators, and the results are amazing. I’ve almost finished the intro for the game, which will also be a song that Sabrina sings in-game.



I can’t share an example yet, but expect something next week.

Animations
No good news here... I’m still struggling to find a good approach for generating high-quality videos. I’ll push this to almost the end, expecting to include little to no animation in Chapter 1, or at most a couple of non-NSFW ones.


Coding
The game’s source code is underway. There’s some progress on folder structure, scenes, and chapters, but nothing worth mentioning yet. The plan is to start thinking about the GUI once I have most of the script and CGs.


And that’s this week’s update! Thanks for following. If you want more random updates about the game, follow me on

I love your art man, looks really great!

Are you using Stable Diffusion? Have you found a good way to get consistent backgrounds across different CG's?

Thanks! I'm using Krita and InvokeAI (lately more Invoke than Krita) with various illustrious checkpoints and LoRAs.

For backgrounds right now, a good prompt, fixed seed, and lots of ControlNet tweaking can get you something decent. But going beyond decent is tough (and in my opinion doesn't add value to the avn).

For example, take the lobby of Babylon and the "same" couch from a different angle.



Another approach is creating variations of the same scene (like day/night, a room with or without a bed, etc). This is easy to do, and the results look great with tools like Nano Banana, Flux Kontext, or Qwen Edit.



A model like GPT-5 can also help generate decent background planes with minimal detail.




Just remember that manual tweaks are often needed, like, drawing and then inpainting or similar adjustments.

Thanks for the explanation, good luck!

Looks very interesting, I like a lot of the characters so far, very beautiful girls. Plus I see femdom listed, so I am very excited about that, hope it gets a bit intense with various kinks.

I will say hope MC name is changeable, that is important to me. But yeah this looks pretty good, keep up the good work.

Thank you so much! Really glad you're liking the girls and that the femdom tag caught your eye

About the MC's name:

• Yes, the MC’s name is fully changeable right from the start (literally the first thing you do), and it works perfectly everywhere in the game – no weird placeholders or anything.
• In update posts and dev comments I’ll keep calling him “Leo” just because it’s easier for us when talking about the story, but in-game it’ll always be whatever name you pick.

About femdom (and some of the other spicier tags):

• You’re right that they’re listed, but we probably should update the tag list to reflect the reality for chapter 1.
• There won’t be any actual sexual femdom content in Chapter 1 yet. It’s being introduced properly with one of the main recurring girls whose whole personality revolves around it. So it’s definitely coming (and it’ll get intense with plenty of kinks, don’t worry), just not right from the first release.

Thanks again for the support and for keeping an eye on the project! Hope you’ll enjoy the ride once it's released
