✅ VoxBridge: A Lightweight Toolkit to Use Sandbox Assets Across Platforms

DappsoverApps · June 13, 2025, 2:46am

1. Executive Summary

We want to deliver an open-source converter that transforms .glTF exports from VoxEdit into files directly importable into platforms like Roblox (using its glTF Importer plugin) and Unity (via the Khronos glTF importer package). This tool removes manual rework and lets Sandbox creators repurpose voxel models across multiple engines.

Main Goal:
Allow VoxEdit-exported assets to be used in external 3D/UGC platforms without manual format adjustments.

Benefits:

Extends visibility of Sandbox creations
Lowers technical friction for creators
Advances The Sandbox’s interoperable-metaverse vision

2. Problem Statement

VoxEdit lets creators export their work as .glTF, but those files are not ready to use elsewhere. If you try bringing these files into platforms like Roblox or Unity, things break, textures don’t show up right, materials need to be fixed, and you’re stuck editing files manually just to make them usable. It is frustrating, slow, and way too technical for most creators who just want to share their work.

This blocks a lot of people. For example, Voxel artists who want to showcase their creations in other spaces can’t do that. and builders hoping to reuse Sandbox assets in other engines have to hack their way through it or just give up on the process. The Sandbox itself misses out on the visibility and reach that could come from having its content travel freely across the open metaverse.

If this is not fixed, great work will keep getting stuck in one place. And creators who should be thriving across worlds will stay limited to just one.

3. Proposed Solution

We’re building a simple open-source tool that lets creators take assets exported from VoxEdit and make them work instantly in platforms like Roblox and Unity without no manual fixes, no Blender workarounds.

Here’s how it works:

Export your asset from VoxEdit as .glTF or .glb
Run it through the tool
Get a version that’s ready to drop into Roblox Studio or Unity

It’ll be built as a command-line tool, with an optional interface for ease of use. It supports local files and may support IPFS in later updates.

Key Technologies:

Blender scripting API : To fix asset structure
glTF tools : To process and clean up files
Node.js or Python : For the core logic
Roblox & Unity importers : To ensure compatibility

How it connects to The Sandbox:

Works with VoxEdit exports.
Doesn’t interfere with Game Maker.
It expands how creators use what they’ve already built.

Hello @DappsoverApps,

Thanks for your proposal! I love the idea. Could you please provide more information on the following two points?

GLTF Performance in Unity and Roblox

How do you plan to improve the performance of GLTFs for Unity and and Roblox? Existing libraries allow exporting GLTFs to Unity, but they result in very poor performance within the engine. I’d appreciate it if you could elaborate on your optimization strategies for this.

Milestone Deliverables

Please expand on the deliverables for each milestone so we have a clearer understanding of what will be provided.

Hello @yuelwolf ,

Thank you for taking out time in reviewing our proposal. We are glad to hear you love the idea. Below are the answers to the questions you asked:

1. GLTF Performance in Unity and Roblox

While there are existing tools to import glTF files into Unity or Roblox, most don’t properly optimize these assets. Often the imported assets cause lag, load slowly, or fail entirely, especially in Roblox, due to its strict limit of 10,000 triangles per MeshPart. Unity assets with too many separate meshes also tend to perform poorly, particularly on mobile devices.

Our tool specifically targets these common problems:

It combines meshes sharing the same material. This reduces Unity draw calls and keeps Roblox assets within triangle limits. For assets exceeding Roblox limits, the tool automatically splits them into manageable parts.
It simplifies geometry using Blender’s Decimate modifier, preserving visual quality while significantly improving performance.
It packs smaller textures into a single optimized texture atlas and resizes larger textures, reducing memory usage and load times.
It adapts material settings explicitly for Unity and Roblox, ensuring assets look correct immediately upon import.
For Unity users, the tool optionally generates Level of Detail models to support smooth performance across desktop and mobile devices.

Additionally, after each conversion, creators get a straightforward summary report indicating triangle count, mesh complexity, texture usage, and overall asset performance.

To demonstrate these optimizations, we’ll test three representative VoxEdit models (an avatar, a prop, and a building) and share clear before-and-after performance benchmarks. All tests and outcomes will be openly available for the community in our public repository. The result is not just correct file formats, but genuinely optimized and smoothly performing assets for creators to immediately use in Unity and Roblox.
