CC0-licensed 3D environments and props, converted to GLB for universal use.
This repo makes the Polygonal Mind Open Source Initiative more accessible by converting everything to GLB format — ready to drop into any engine, web project, or 3D tool without dealing with FBX imports or Unity packages.
Focus: 3D environments and props only. For avatars, check out open-source-avatars — VRM-formatted characters ready for VRChat, Vtubing, and games.
CC0 asset packs from metaverse projects spanning 2018–2023: medieval fairs, retro booths, Egyptian pyramids, neon pagodas, vaporwave rooms, museum pieces, gardens, and more. Originally released as FBX, Unity packages, and platform-specific formats — now all GLB, no gatekeeping.
| ✅ Converted (18 packs) | 🔄 In progress | ⬜ To-do |
|---|---|---|
| XYZ, ABM, Avatar Garden, CA World, Chromatic Chaos VHS, Cryptoavatars Retro Booth, Crystal Crossroads, LowPolyStore (3 variants), Medieval Fair, Momus Park, South DCL (3 variants), The Avatar Show, Tomb Chaser 1 & 2 | Avatar Webcam | Babylon, Dethrone, Underworld |
Stats so far:
- ~991 GLB files ready to use
- ~2.1 GB total (just the models, no bloat)
- Downloaded all packs from the original initiative
- Batch converted FBX → GLB using Blender scripts
- Manual cleanup on each model:
- Materials consolidated
- Textures optimized
- Unused slots removed
- Naming cleaned up
- Colliders preserved where needed
Not just raw exports — curated, tested, ready to use.
Between 2018–2023, my team and I at Polygonal Mind (Zaragoza-based, est. 2015) built environments, games, and virtual spaces for Decentraland, VRChat, The Sandbox, Hyperfy, and more. We made the 100 Avatars daily series, Tomb Chaser platformers, Virtual Market booths, museum installations, and a bunch of weird experimental stuff.
The company closed in 2024, but the work shouldn't disappear. We released many of it under CC0 — this repo is just making sure it stays accessible and easy to use.
