URT3D is a universal 3D asset format with the file extension .urta — designed to help creators and developers share, render, and interact with 3D content more efficiently.
It combines visual content, interactive behaviors, and runtime-ready logic into a single, optimized file that works across:
🔹 Unity 🔹 Bonfire 🔹 Web 🔹 XR platforms 🔹 (Coming soon: Unreal, Godot)
The 3D ecosystem is fragmented — with different engines, formats, and workflows making it hard to deliver interactive content efficiently across platforms.
URT3D solves this by offering:
🔹 A portable, engine-agnostic format 🔹 Built-in behavioral logic (no need to reprogram interactivity) 🔹 Lightning-fast loading times 🔹 Native support for traits and scripting 🔹 A friendly workflow for both low-code and pro developers
.urta File?Every .urta asset can include:
🔹 A 3D model (from .glb or .gltf)
🔹 Preview image and metadata
🔹 Interactive traits (e.g., position, rotation, animation, interactivity)
🔹 Scripts written in MiniScript for behavior
🔹 Optional encryption for secure delivery
URT3D files are created through or programmatically through our SDKs.
URT3D is built for:
🖼️ Creators Drag-and-drop 3D models and convert them without coding.
🧑💻 Developers
Load .urta files in your app, apply traits, run scripts, and connect behavior.
🎯 Teams building interactive 3D content Use one file format to power experiences across Unity, Bonfire, WebGL, and beyond.
🔹 Convert Your First Model 🔹 Install the SDK 🔹 Explore Traits 🔹 Add Interactivity with MiniScript 🔹 See Best Practices
URT3D makes interactive 3D easier — one .urta at a time.
