TRELLIS is an open-source ai 3d project by microsoft (microsoft/TRELLIS on GitHub). It has 13,755 GitHub stars and 1,352 forks, is released under the MIT license, and was last updated on GitHub on 26 June 2026.
Game engines and modelers for handcraft; AI tools for text-to-3D assets.
Mature installers and package managers on every platform.
Nodes, scripts, or prompts — each tool has strong community tutorials.
Standard formats (glTF, FBX, OBJ) move assets between tools.
True three-dimensional pipelines, not flat approximations.
Modern pipelines with PBR, GI, and post-processing.
Text-to-3D and image-to-3D for rapid prototyping.
Ship commercial games without revenue share.
Modify the engine itself — impossible with closed tools.
Several engines support immersive targets out of the box.

# see README for the exact launch commandIt is an open-source project at microsoft/TRELLIS with 1,352 forks. Check the repo's contributors and recent commits to see how active maintenance is.
MIT licensed — use it commercially, no strings attached.
Great for prototypes and background assets; hero assets still want an artist's pass.
Visual scripting covers a lot; GDScript/Python is easy to pick up.
Godot has shipped commercial hits; for AAA-scale productions the big two still lead.
