UModeler X becomes free: 3D modeling in Unity without paying a subscription

Published on May 15, 2026 | Translated from Spanish

The modeling, texturing, and rigging plugin UModeler X has eliminated its annual cost of over $100, now being offered for free to all Unity developers. This tool, a finalist in the Unity Awards 2024, allows you to create low-poly models, apply UVs, paint textures, and rig characters directly in the editor. Its simplified approach positions it as an accessible alternative to ProBuilder for independent studios and artists seeking agility in their 3D workflow.

A Unity editor shows the UModeler X interface with a textured low-poly model, surrounded by modeling and rigging tools.

Modeling, UV, and rigging in the editor without leaving Unity 🎨

UModeler X integrates features that previously required external software: polygonal modeling with extrusion and bevel tools, automatic UV mapping, texture painting with layers, and a bone-based rigging system. The plugin runs within the Unity editor window, enabling rapid iterations without context switching. It supports export to FBX and OBJ formats, and its collision engine adapts to low-poly geometries. Developers of commercial titles such as Garden Paws have used it for prototyping and final production, validating its stability in real-world projects.

Now that it's free, there's no excuse for your cube to still be a cube 😅

Until yesterday, paying $100 a year for a plugin was the perfect argument to justify your potato-shaped models. But now that UModeler X is free, your main character can no longer be a cylinder with eyes. If after this you're still using untextured primitives, you'll have to accept that the problem wasn't the price, but your patience with vertices. At least automatic rigging will save you the drama of animating a cube with legs.
