Model your levels.
Inside Godot.
Block out and edit level geometry without leaving the 3D viewport. Draw shapes on a snapping grid, push faces around, cut doorways, paint vertices, punch boolean holes. Every mesh is a plain MeshInstance3D that your game already understands.

Model, texture and bake without switching apps.
You draw, edit, UV, paint and bake in the same scene, and the mesh stays a Godot node the whole time.
Draw-in-viewport shapes
Cube, plane, cylinder, cone, prism, stairs, curved stairs, arch, door, sphere, torus, pipe, and free-form poly shapes, all drawn straight onto the grid. Parameters stay editable after you commit.
Element editing
Object / Vertex / Edge / Face modes with marquee, loop & ring, grow/shrink, select-similar, and hover preselect. Selections carry over when you switch modes.
Mesh operations
Extrude, inset, multi-segment bevel, bridge, weld, connect, insert loop, subdivide, merge, detach, fill hole, and a cut tool that copes with concave faces.
Grid & vertex snapping
A reference grid on any axis plane, with line spacing set by the snap step. Hold V while dragging to land a vertex exactly on any other vertex, even one on a different object.
Adjust-last-operation
A live parameter panel like Blender's: run a bevel first, then dial in the segment count. It still commits as one undo step.
Auto-UVs and a UV editor
Automatic per-face planar UVs, and a 2D editor for when you need more control: projection, sew & split seams, island select, copy/paste, texel-density normalize.
Vertex painting
A brush with radius, strength, and falloff, painting per-corner color. Comes with a two-texture blend shader driven by painted alpha, handy for dirt and wear.
Booleans
Union, Subtract, and Intersect on Godot's Manifold CSG kernel. If a mesh isn't watertight, Unibuilder selects the offending edges so you can see what to fix.
Game-ready output
Collider & Trigger volumes, convex/trimesh/ramp auto-collision, bake to plain MeshInstance3D with lightmap UV2s, OBJ+MTL and glTF export, and a converter that turns existing triangle meshes into editable ones.
Greybox to game-ready in one place.
Every step happens in the editor you already have open.
Block out
Drag shapes onto the grid. Stairs get a step per snap increment, and everything comes out watertight.
Shape it
Shift-drag to extrude, cut doorways, bevel corners, boolean holes. Any op can be adjusted after you run it.
Texture it
Auto-UVs do the work by default. Drop materials onto faces, and open the UV editor when you want control.
Paint it
Vertex-paint color coding, or blend two textures with the alpha brush.
Ship it
Auto collision, lightmap-ready bakes, invisible collider volumes. Meshes load fine without the plugin.
