Skybox AI (Blockade Labs)

Open-weights image-to-3D model with PBR material generation that you can run on your own hardware.

Free tier + paid

→

Rodin generates 3D models from text or images, with options like high-poly quad meshes; the platform also lists HDRI and texture generators.

Verdict: For high-detail 3D generation; commercial rights on the Free and Creator tiers are unverified, so check its terms before you ship.

Free tier + paid

→

Game ideation and asset tool: concept generation, sprites and sprite sheets, textures, plus a Unity editor plugin and API.
