Polyshire

Polyshire is a cozy home for web-ready 3D. It's a store of low-poly assets and themed kits built for the web first: flat-shaded vertex colors, a single material and one draw call per model, real-world scale, and files measured in kilobytes instead of megabytes. Every asset ships two ways, as a GLB that imports into Unity, Godot, Unreal and Blender, and as a one-line ES module for three.js with no loaders at all. Parts that should move (lids, wheels, doors) are named groups with correct pivots, so a one-line rotation animates them, and everything in a kit shares one palette and one scale so your scene looks like it belongs together.

What sets Polyshire apart is that its assets are remixable: they carry built-in knobs for curated palettes, per-part colors and shape options. You adjust them in the store viewer with no 3D software and download the GLB in your colors, or use the parametric module to generate variants in code. Each asset publishes its knobs as machine-readable JSON, so the AI tools you build with can read them and remix on your behalf. Free assets are hotlinkable straight from the CDN, licensing is simple, and everything is made to drop into your project and just work.
