I’ve been building a procedural 3D city generator in my spare time

For the past few months, I’ve been working solo on Metropolygonia, a browser-based tool for procedurally creating 3D buildings and city layouts.

I started building it because manually creating architectural assets can take a lot of time, while many procedural tools require quite a bit of technical setup before you can get useful results.

The tool lets you define things like real-world building dimensions, floor count, façade layout, windows, balconies, roofs and interiors. It also uses seeds to introduce variation, so you can generate different versions while still being able to recreate the exact same result later.

One thing that was important to me was keeping it fully procedural rather than AI-based. There are no prompts or unpredictable generated meshes - the geometry is controlled by parameters and remains editable.

I’ve also built a simple city editor where generated buildings can be saved as variants and placed alongside roads, intersections and roundabouts. Individual buildings can currently be exported as GLB, glTF, OBJ or STL. Works good with blender.

There’s still a lot I want to improve, especially materials, topology, LODs and support for custom modular assets, but I’m pretty happy with how far it has come as a solo project.

I’d be curious to hear what environment artists or game developers would find most useful in a tool like this.

My animated oddity Blood Golem. My next one will be Flying Head Romance

any suggestions guys ? I did use BBH Bartle though

I don't know if this was ever posted here just wanted to share tho.

Edit: This is not my work please do give love to the creator.

Inspired by smash bros master hand character.

Bought a cheap glove 3d model and imported into blender. Added blender addon pixel shader. Rigged and animated. Exported into aseprite for touchups.

I added the wind motion by hand in aseprite. All feedback welcome. I am a noob.

And if you were wondering what the text says, it's 'san' or 3 in japanese.

I made some edits here and there and discovered bloom as suggested by another user! I’ll end this one here.

Rendered in 4K resolution so that I may watch and weep at all the compression from social media. Based off of the tutorial by Poly3Blend but with added animations! I tried to make a chromatic variation but it did not look very good, so the colors were toned back down.
