How to use LLMs with unreal engine 5.5 to generate blueprints, assets etc.?

Hacker News - Fri, 03/28/2025 - 8:26am

Anyone knows of a way to generate assets or blueprints for common cases using an LLM for unreal engine 5.5. An example prompt would be like submitting an image of union station new york and generating a 3d asset for the entire building or a prompt like "Create a third person player. Put a switch on the wall. When the character flips the switch, turn ON the light if it is turned OFF and vice versa" and this prompt generates the necessary blueprint

Show HN: Reconquer Engine – A Full-Stack JavaScript Mmorpg Engine and Game

Hacker News - Fri, 03/28/2025 - 8:25am

Hi everyone, I'm Chris, the developer of Reconquer Online (https://alpha.reconquer.online/). Today, I'm excited to share Reconquer Engine

https://github.com/ReconquerOnline/reconquer-engine.

Reconquer Engine provides all the necessary logic and game assets to build an OSRS-style MMORPG using Javascript. Upon building and running it for the first time, you'll have a fully functional MMORPG. It utilizes gltf-Transform for asset processing, a Node.js server with Express and Socket.io, and WebGL/three.js for browser-based graphics. Simple example implementations for the database, authentication, and payments are included, but you are encouraged to integrate your own systems. The game and engine are developed purely in Javascript (99.9% JS, 0.1% HTML, 0% CSS) including the asset exporter, server, and client.

My Development Workflow:

1. Blender: I create, texture, and animate 3d models.

2. JSON Configuration: For each asset, I define its type and properties in a JSON config file (e.g., inventory item, scenery).

3. Custom Exporter: A JavaScript tool I built iterates through these config files and generates optimized assets for both the client and server.

4. Compilation & Server Start: I compile the frontend Javascript and launch the Node.js server.

Licensing:

Reconquer Engine is released under a license similar to Unreal Engine's: free for non-commercial and small commercial use, with a royalty for larger commercial ventures.

Limitations:

There is very little documentation, although the code and structure itself is designed to be as simple as possible. I think the codebase can be learned fairly quickly through inspection or with an LLM helper.

Future Plans:

* I'm working on creating a comprehensive tutorial to help others get started.

* I plan to further improve the tooling, with the potential goal of creating a browser-based MMORPG maker.

* I'm also exploring the development of an AI agent to very easily create new content.

Please try it out! It's very easy to get up and running. Also, I plan on posting a tutorial on my Youtube channel (https://www.youtube.com/channel/UCEqXVu4orzl7nnkwJZ72AOg)

Thank you for checking it out!

Best,

Chris @ Reconquer Games

Show HN: GratefulMe – A privacy-focused gratitude journal app

Hacker News - Fri, 03/28/2025 - 7:49am

I built a gratitude journaling app that implements CBT techniques to help users develop a daily mindfulness practice. Research shows that consistent gratitude practice can significantly improve mental wellbeing, and I wanted to create a tool that makes this accessible.

The app focuses on these core principles:

- Privacy: All data stays on your device with an offline-first approach - Simplicity: Clean interface optimized for quick daily entries - Consistency: Streak tracking and gentle notifications to build a habit - Organization: Category system to identify patterns in what brings you joy

Tech details:

- Built with React Native/Expo - Local SQLite database using expo-sqlite and drizzle-orm - In-app purchases via RevenueCat - Minimalist architecture with a focus on performance

As a developer, the most valuable lessons came from handling the entire process solo - from initial concept through development to App Store submission and payment infrastructure.

The current roadmap includes customizable notifications, dark mode, and an achievements system.

Any feedback or suggestions would be valuable for future iterations.
