Open-weights image-to-3D model with PBR material generation that you can run on your own hardware.
Verdict: 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.
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.
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.
Verdict: 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.
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.
Verdict: For pixel-art devs who want pay-per-image pricing with no subscription; the site says all output is yours for commercial use.
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.
Verdict: For studios that want custom style models trained on their own art; commercial use needs a paid plan (free output is personal/evaluation only).
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.
Verdict: For game-ready props from editable templates with Unity/Unreal plugins; the free plan is personal-use only.
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.
Verdict: For 3D models with retopology and engine bridges; the free plan is non-commercial, so shipping assets requires a paid plan.
AI built into the Unity Editor: an Assistant for project questions and code, plus generators for images, textures, materials, sounds, 3D models and animations, metered in Unity Credits.
Verdict: For Unity users who want AI inside the editor, with monthly credits included on Personal, Pro and Enterprise plans; AI-output licence terms are unverified.
