Using Wildform packs in Three.js
Your order page lists every download that is ready for your pack. One purchase covers Unity, Three.js, Unreal, and Godot. No extra purchase.
The Three.js download is twelve GLB files with PBR textures already embedded. Load the .glb you need with GLTFLoader. Do not convert FBX.
Preview: double-click Open Preview.command (Mac) or Open Preview.bat (Windows). Or from the unzipped folder run python3 -m http.server 8765 and open http://127.0.0.1:8765/demo.html. A double-click of demo.html itself will not load the models. That page is a viewer. Put the GLBs into your own scene.
