Synty POLYGON is built around Unity and Unreal: the packs we checked ship as a Unity package and an Unreal project plus FBX/OBJ source files, from a very large stylised catalogue. 3D Asset ships glTF 2.0 first — Draco GLB for the web, typed React Three Fiber components and a copy for desktop tools — at one-time prices from $13 per pack.

When Synty is the better choice
- You work in Unity or Unreal and want drop-in prefabs, demo scenes and engine materials.
- You need a huge range of themes in one matching art style.
- Your team already standardised on the POLYGON look.
When 3D Asset is the better choice
- You ship in the browser: files are already glTF with Draco and WebP, and every model has a typed React Three Fiber component.
- You want realistic PBR city, suburban and industrial kits, not only stylised art.
- You want parametric variants — colours, sizes, signs, armored versions — exported from a browser editor.
- You prefer one-time pricing per pack without seats or subscriptions.
Frequently asked questions
Can I use Synty assets in three.js?
Technically yes: convert the FBX source files to glTF (for example through Blender) and compress them. Whether a browser build is allowed is a license question; read Synty’s license for your pack before shipping.
Does 3D Asset work in Unity?
Yes. Import the glTF files with Unity’s glTFast package; some packs also include a ready URP package with prefabs.
Which is cheaper?
For a single pack, 3D Asset prices start at $13 and go up to $59; every pack together is $95 once. Synty prices vary by pack and sale, and a subscription is also available.
