An AI-generated 3D model, cleaned up and reduced in Blender, UV-unwrapped with baked detail, and imported into Unity, Godot or Unreal.

For each open-weights model a game dev is likely to run locally: the licence, whether outputs can be used commercially, any revenue, user or territory limit, and the catch, each linked to the licence text.

Highest-ranked of these tools on 3D Arena's blind human-preference leaderboard: Meshy 6 is #3 and Meshy 7 is #5 of 24 image-to-3D models. Free-plan output can be used commercially if you credit Meshy (CC BY 4.0). 3D Arena leaderboard
Text-to-3D and image-to-3D model generation with AI texturing; paid plans add animation with 600+ motions. DCC bridge listed for Roblox, Blender, Godot, Unity and Unreal.
For quick text- or image-to-3D props with Godot/Unity/Unreal bridges; free output is CC BY 4.0, so you must credit Meshy unless you pay.
#2Best free (self-hosted)Independent tests
On 3D Arena, Hunyuan3D 2 is #8 and Hunyuan3D 2.1 is #10 of 24 image-to-3D models. Free open weights you run on your own GPU, but the licence doesn't cover the EU, UK or South Korea. 3D Arena leaderboard
Open-weights image-to-3D model with PBR material generation that you can run on your own hardware.
For devs who can self-host a 3D model generator at no licence cost; the licence excludes the EU, UK and South Korea, and products over 1 million monthly users must request a licence.
#3Game-dev fit
No independent quality tests found. Ranked on game-dev fit: commercial use on paid plans; Godot, Unity, Unreal integrations; API and official MCP server. Only Tripo's older open-source TripoSR model is on 3D Arena (#20 of 24). It isn't the model behind Tripo's paid service, so we don't use it here.
Text/image/multi-view to 3D model generation with retopology, segmentation and up to 4K/8K texture generation. DCC bridge lists Blender, Unity, Unreal, Godot and others.
For 3D models with retopology and engine bridges; the free plan is non-commercial, so shipping assets requires a paid plan.
#4Game-dev fit
No independent quality tests found. Ranked on game-dev fit: commercial use on paid plans; Godot, Unity, Unreal integrations; API.
Template-based and AI 3D generator for game-ready props and objects, with browser editor and plugins for Unity, Unreal and Blender on paid plans.
For game-ready props from editable templates with Unity/Unreal plugins; the free plan is personal-use only.
#5Game-dev fit
No independent quality tests found. Ranked on game-dev fit: commercial use allowed; Godot, Unity, Unreal integrations; API and official MCP server.
Pixel-art-specific image models for sprites, tiles, tilesets and animations, plus low-poly 3D model generation with export for Godot, Unity and Unreal. Also sells an Aseprite extension.
For pixel-art devs who want pay-per-image pricing with no subscription; the site says all output is yours for commercial use.
#6Game-dev fit
No independent quality tests found. Ranked on game-dev fit: commercial terms not stated by vendor; Godot, Unity, Unreal integrations; API and official MCP server.
Rodin generates 3D models from text or images, with options like high-poly quad meshes; the platform also lists HDRI and texture generators.
For high-detail 3D generation; commercial rights on the Free and Creator tiers are unverified, so check its terms before you ship.
#7Game-dev fit
No independent quality tests found. Ranked on game-dev fit: commercial use on paid plans; Unity, Unreal integrations; API and official MCP server.
Production-focused generative platform for game art: train custom style models on your own assets, generate images, textures, 3D meshes, video and audio. API-first with Unity/Unreal integration.
For studios that want custom style models trained on their own art; commercial use needs a paid plan (free output is personal/evaluation only).
#8Game-dev fit
No independent quality tests found. Ranked on game-dev fit: commercial terms not stated by vendor; Unity integration; official MCP server.
Unity's AI tools (Unity is retiring the "Unity AI" name): an in-editor assistant for project questions, code and Editor actions, plus generators for images, textures, sounds, 3D models and animations, metered in Unity Credits. The Unity CLI, MCP server and Unity's official agent plugin are free.
For Unity 6 users who want AI inside the editor: credits are included on Pro, Enterprise and Industry, while Personal gets a 14-day trial and then a paid subscription. Unity says you own the outputs, but third-party generator terms also apply.
