Procedural Tiles is a Blender add-on built around a library of over 100 shader nodes that emulate tile patterns. It lives in the material node editor, and each node is designed to be used like Blender's Voronoi or brick texture. Because of that, no new workflow is required: existing shader node knowledge transfers directly.
The nodes cover a range of uses inside a shader graph. They can define the core pattern of a floor or wall, act as noise for surfaces, break up symmetry and repetitive tiling, or hide the hard edges that appear when a texture tiles. The library is described as growing, with new tiles added over time.
Procedural Tiles is compatible with Blender 4.2 LTS and newer, requires no special permissions, and is released under the GNU General Public License v3.0 or later. Source and issue tracking are available on the developer's GitHub page.
