[Dev News] Unibuilder – ProBuilder For Godot - xSicKxBot - 10-27-2026
UniBuilder is a new Godot 4 addon that gives Godot functionality very similar to what Unity’s ProBuilder provides. If you are unaware, this means it provides full in game engine 3D modelling tools, making it easy to rapidly design 3d levels and stand-ins without a need for an external modeling tool like 3D Max, Maya or Blender.
Features of Unibuilder include:
- Draw-in-viewport shape tools: cube, plane, cylinder, cone, prism, stairs, curved stairs, arch, door, sphere, torus, pipe, poly shape. Parameters stay editable in case you mess up.
- Object / Vertex / Edge / Face editing with loop/ring/grow/similar selection
- Full op suite: extrude, inset, multi-segment bevel, bridge, weld, connect, insert loop/vertex, subdivide, merge, detach, fill hole, modal cut tools, a partridge in a pear tree.
- Auto per-face UVs plus a full 2D UV editor (projection, sew/split, islands, copy/paste, texel normalize), multi-material meshes with drag-and-drop assignment, smoothing groups, vertex paint with a dual-texture blend shader.
- Booleans on Godot’s CSG kernel.
- Game-ready output: Collider/Trigger entity volumes, convex/trimesh/ramp auto-collision, bake to plain MeshInstance3D with lightmap UV2s, OBJ+MTL / glTF export, and “Convert to Unibuilder” for existing triangle meshes.
- Pure GDScript, no C#/.NET required.
There is a near fully functioning demo version of the Unibuilder addon available on Itch.io, the version I used in the demonstration video below. The full version is also available on Itch.io for a one time purchase of $24.99 USD.
