Blender 4.0+ add-on
UVs for architecture, in four buttons
Tiled textures stay seamless across walls, floors and mouldings, whatever their local transforms. Every tool works on all selected meshes at once, from Object Mode.
What it does
World-Space Unwrap
Box-projects UVs aligned to world XYZ axes. Tiled textures stay seamless across object boundaries regardless of local transforms. Scale control (default: 1 m = 1 UV unit).
Normalize Texel Density
Rescales UVs across all selected objects to a uniform target density (pixels per metre). Works per-object so each is corrected independently.
Auto Seam from Angle
Marks seams on concave (recessed) edges above a configurable angle threshold. Seams land on hidden corners, not visible faces — ideal for columns, mouldings, and baseboards.
Clear Seams
Removes all UV seams from selected objects.
Typical workflow
- Select all meshes → Auto Seam (marks hidden corners)
U → Unwrapusing Blender's native unwrap (now guided by your seams)- World-Space Unwrap to align UVs to world axes
- Select all → Normalize Texel Density to unify texture scale across the scene
