1. Executive Summary
Sandbox players pour time and SAND into customizing avatars, yet those identities are trapped in-game. Without a simple way to export, creators lose sales, streamers hide behind generic models, and Sandbox itself misses free brand exposure in Unity, VRChat, and live-streaming hubs. Every week we wait, more metaverse spaces open without a single Sandbox face in sight. The DAO grant program sunsets on 31 August; approving this toolkit now lets us unlock avatars for Season 5 hype instead of “maybe next year.”
Goal: ship an open-source pipeline; VRM exporter, Unity / VRChat plugin, and desktop streaming helper so any holder can take their voxel persona anywhere by August deadline. Our team has already prototyped core conversion code and completed deep R&D on WalletConnect ownership checks. With funding, we will finalize, document, and launch before 31 August, ending the pain of locked-in avatars and amplifying Sandbox’s brand across Web3.
Impact:
-
Players can use the same avatar across Unity, VRChat, and streaming platforms.
-
Avatar creators gain wider visibility and opportunities for monetization.
-
Sandbox benefits from increased visibility and adoption within the broader Web3 and gaming communities.
2. Problem Statement
Currently, Sandbox avatars are restricted to The Sandbox platform, limiting the value of avatar NFTs. Players who wish to reuse their avatars in external platforms (such as Unity games, VRChat experiences, or live streaming) face significant manual effort. This issue causes:
-
Identity Fragmentation: Players forced to manage different characters for each platform.
-
Lost Visibility: Avatar creators and brands miss out on exposure across wider audiences.
-
Marketing Opportunities Missed: Sandbox avatars remain unseen outside the ecosystem.
3. Proposed Solution
| Component | Purpose | Benefit |
|---|---|---|
| Avatar Converter (CLI) | Exports Sandbox avatars to VRM 1.0 format (mesh, rig, textures). | Simple, no-fuss avatar exports |
| Unity / VRChat Plugin | Unity 2022 LTS package (UniVRM) for direct VRM import. | Easy integration for Unity games and VRChat |
| Streaming Helper (Electron 30) | Lightweight desktop app using webcam or animation presets for avatar streaming. | Streamers adopt Sandbox avatars with minimal effort |
| Ownership Check | WalletConnect v2 verification confirms NFT ownership on Polygon. | Ensures proper NFT ownership securely |
4. Team
Our team recently collaborated with the Sandbox DAO Grant to successfully build and launch VoxBridge, a widely adopted voxel asset converter. We delivered this open-source toolkit within just three weeks, rapidly solving a core Sandbox developer pain point and empowering creators to seamlessly integrate their assets into Unity and Roblox; demonstrating our deep understanding of the Sandbox ecosystem and technical execution capability.
