New Year Collaboration: Join Crateria City Development

[Umbawa_Sarosong]

Happy New Year, Three.js community

As we start 2026, I’m inviting designers, developers, and 3D enthusiasts to voluntarily collaborate on Crateria City, a detailed game map available here: Crateria City on RenderHub

You can also explore the live demo here: Crateria City Live Demo

Why Participate
Collaborating is a unique opportunity to:

• Gain Hands-On Experience: Work with a browser-based Virtual Experience Engine built with Three.js and Web Physics

• Expand Your Skills: Improve modeling, interactivity, optimization, and immersive visualization skills transferable to game development, architecture, or virtual design

• Collaborate and Network: Connect with other designers and developers, share ideas, and contribute creatively to a growing virtual world

• Showcase Your Work: Contributions can be used in your portfolio or for personal learning

Reference Engine
The engine’s architecture and workflows are available in this Virtual Experience Engine book to help participants experiment independently

Participation Terms
Participation is completely voluntary. Contributors are free to join or leave at any time. There is no obligation or recourse to me regarding contributions, decisions, or outcomes. This collaboration is purely for learning, experience, and creative exploration

Who Can Contribute

• Designers and architects familiar with 3D tools like Blender, SketchUp, 3ds Max, or Rhino

• Developers interested in interactive 3D web applications

• Anyone passionate about immersive virtual environments

Let’s Make 2026 Creative and Interactive
By participating, you can help turn Crateria City into a fully interactive, living virtual world, while gaining practical skills and experience in a voluntary, flexible, and self-directed way

Add Your Own GLTF Models

This feature provides a blank browser-based virtual environment where architects, designers, and developers can add their own GLTF models and view them directly in a real-time Three.js experience.

Participants can use any GLTF asset from Sketchfab, or export their own models from SketchUp or other 3D tools, convert them to GLTF using Blender, and then drag and drop the model directly into the scene.

All files are handled locally in the browser.
No files are uploaded, stored, or sent to a server. The drag-and-drop process is purely client-side, making it suitable for private testing, experimentation, and learning.

Because the environment is intentionally minimal, contributors can focus on:

Testing scale, orientation, and spatial placement
Validating assets for real-time web performance
Understanding how GLTF models behave inside a Three.js workflow

Access the blank virtual environment here:

Participation is fully voluntary and self-directed, allowing contributors to explore, iterate, and learn at their own pace.
