I've added an NPC event system that lets the characters react to all kinds of situations. The standard events that only have dialog and/or animation reaction can be easily added via database without needing any code, but custom code for specific events can also be added. #indiegame #procgen

I'm so excited! Been looking forward to this one!

Vuntra City @vuntracity.bsky.social · 28/09/2026

I've added a way for the NPCs to say things outside of the player dialog. So they will be a lot more chatty now! There will be many situations in which they will voice their opinion, and their comments will depend on their personality. #gamedev #indiegame

New devlog on how I made 4 million NPCs playable in VR. Now, this performance is not ideal, it's more of a baseline, so the optimization work is not quite done. But it's a huge improvement from where I started. Check it out! www.youtube.com/watch?v=FkiA... #gamedev #indiegame #procgen

Ok I think I did it. 60+ FPS in VR on max settings, with 4 million total NPCs in the most crowded area of the city. Still not as stable as I'd like it to be, but it is quite playable so I'm happy! #gamedev #indiegame

Enjoying the last warm days of this year at the local park's jazz festival, and I can't help but feel that I need more cozy outdoor spaces like this in Vuntra City. I already have bean bags and string lights, but none of them spawn outside 🤔

Everyone is playing around with DLSS5 and debating whether it's good or not, so here I have a totally legitimate comparison of Vuntra City with DLSS5 off and on. See for yourself!

Two screenshots side by side, one of a normal Vuntra City character and the other of a similar but more detailed character who bears uncanny resemblance to Lucia from GTA6, but totally isn't her.

Just dropped a new devlog where I outline my struggles with increasing my city's population from 1 million to 4 million. It's kind of a work in progress devlog, but I hope it'll be interesting nonetheless. youtu.be/XsyYkEZF0rQ #gamedev #indiegame #procgen

Just heard about a cool pattern generator website bookofshapes.com. I wish they supported tiling patterns as well, then I'd totally use it to generate some new wallpapers for Vuntra City.

We recently got accused of using AI for music in our game and, while it's disheartening, it encouraged me to make a thread about making music for games, what it takes, and why it can be heartbreaking to be accused or even suspected of something we detest. 🧵Long thread follows:

I made the NPCs take their clothes off when relaxing at a spa and get into the hot tubs. Implemented an entire outfit system for it, so I can later use it to give them other temporary outfits. Also added steam to make the hot tubs actually look hot! #gamedev #indiegame #procgen

By the way, I am working on optimizing the game to run with >4m NPCs instead of ~1m that I started with. I'm still not sure I will succeed, as there are several performance bottlenecks that make it very hard, but the city sure looks so much livelier with quadruple the population! #gamedev #procgen

Vuntra City @vuntracity.bsky.social · 25/08/2026

Apparently, when there are too many NPCs in the same interior, they start playing a game of musical chairs of sorts. Watching them fight for a seat is pretty hilarious! #gamedev #procgen #indiegame

Don't have anything new to show this week because I'm working on performance improvements. So here's a sunny city for #screenshotsaturday. #gamedev #indiegame

Can't sleep because of a cold that I caught somehow, so it's time for some more shader experiments (WIP).

Vuntra City @vuntracity.bsky.social · 09/08/2026

I messed up my sky shader for a second and got this wonderful effect. The fun part about using a sky sphere with custom colors rather than a physically based atmosphere is that I can actually pull stunts like this in the game - unique weathers with weird sky or cloud colors for special events.

I just got back from an awesome seaside vacation and I'm back at work! But first things first. As I was swimming in the moonlit sea at night, I couldn't help but feel that Vuntra City has been without a moon for too long. So I made a moon. #gamedev #indiegame #procgen

Ok here's a life hack I just learned for crowded touristy areas: you enter any expensive hotel and ask about their rooftop bar. There's a good chance they have one and it'll be empty and quiet because they don't advertise it outside of the hotel and most people don't know they can just come in.

Vuntra City @vuntracity.bsky.social · 30/07/2026

I'm doing some real life city exploration while I'm on vacation. Just saw a building that looked like it had a rooftop terrace from the street. So I went in to see if I could go up there and they let me. Turned out to be a rooftop bar that looks eerily similar to the Vuntra City rooftops.

A box of... something. I'll find out when I open it.

Vuntra City @vuntracity.bsky.social · 24/07/2026

Increasing the city population to ~4 million, combined with the changes in the distribution of citizens, makes the interior spaces almost as packed as they should be. Now the hardest part - to optimize it all so it can run with a decent framerate. #gamedev #indiegame #procgen

First look at the interior schedule WIP (time sped up). I'm trying to give every type of interior somewhat realistic "work hours", so you may notice that more interiors will be lit during the evening and fewer in the morning. #gamedev #indiegame #procgen

Vuntra City @vuntracity.bsky.social · 19/07/2026

The terraces get so cozy sometimes, they really make me want to implement more elevated outdoor spaces (and I will, hopefully). #gamedev #indiegame #procgen

Vuntra City @vuntracity.bsky.social · 16/07/2026

I'm back to working on the NPCs and I have implemented overrides that allow an NPC to disconnect from their GPU calculated schedule and then gradually return to it. This override also kicks in any time the NPC is too far from their anchor, making it easier for the player to find them. #indiegame
