Leadlight – Stained Glass Generator for Blender

👉 See all my Blender addons on BlendKit >

Leadlight builds leaded stained glass windows in seconds: pick a design, then change the outline, the lead pattern, the colors and the glass while the window rebuilds live. Every window is one clean mesh at real size, ready for churches, homes, castles, games and product shots.

Features
- 46 designs in five families: Gothic lancets and tracery, rose windows and oculi, Victorian and Arts & Crafts doors, Tiffany and Art Nouveau, modern and dalle de verre
- 13 outlines: Gothic, round, segmental, ogee, Tudor and trefoil arches, circles, fanlights, foils, polygons and lozenges
- 18 lead patterns: medallions, diamond quarries, roses, roundels, Tiffany flowers, Art Nouveau, Art Deco, Prairie, kaleidoscope, mosaic and more
- Trace your own picture into lead lines and glass colors
- 18 palettes taken from real windows, gradients and per-piece hand-made variation
- Ten glass textures (antique, seedy, hammered, streaky, ripple, glue chip, drapery, crackle) and opalescent glass that glows with backlight
- Round or flat lead came, Tiffany copper foil or concrete joints, with solder at every joint
- Stone, wooden and metal frames, mullions, Gothic tracery and iron saddle bars
- One-click Backlight, Surprise, Vary and New Colors; game mode material for export
