Rigged, animated characters and creatures from one image
Pay-per-image pixel-art sprites and tiles
What it does
Image or text to a textured, rigged and animated 3D character or prop, exported as GLB, FBX or USDZ with skeleton, skin weights and baked clips. Studio, REST API and MCP server share the same jobs.
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 rigged, animated characters straight into Godot, Blender, Unity or Unreal; purchased-credit output is commercial and royalty-free, but there are no free credits.
For pixel-art devs who want pay-per-image pricing with no subscription; the site says all output is yours for commercial use.
