Set dressing eats art budgets: crates, furniture, food, clutter — props players walk past in half a second. Image-to-3D AI is now good enough for exactly this tier of asset: photograph or find a reference, generate a textured mesh, drop it in the scene.
The pipeline
- Generate a GLB from your reference on Pic2Mesh (free, ~1 minute, 2K baked texture)
- Unity 2022.2+ imports glTF/GLB via the official com.unity.cloud.gltfast package — drag the .glb into Assets and it appears with materials
- For older Unity, convert GLB→FBX in Blender (import glTF, export FBX) — two clicks
What to expect from AI meshes in-engine
- Poly counts run 20–80k triangles — fine for hero props, heavy for mobile background clutter. Run Unity's Mesh Simplify or Blender's Decimate for LODs.
- Textures are baked diffuse — lighting response is basic. Great for stylized and mid-fidelity scenes; AAA hero assets still need an artist.
- License is clean: TRELLIS is MIT, outputs from your own images are yours to ship commercially.
Where it fits (and doesn't)
Perfect: prototyping, game jams, background props, blockout replacement, indie set dressing. Wrong tool: characters that need rigging, hard-surface hero weapons, anything with strict topology requirements. For those, budget artist time — for everything else, generate it free.
