Bird Nest Weaver builds woven bird nests procedurally in Blender. Pick one of 19 real-world nests, or shape your own with 98 settings, and the nest rebuilds itself as you change them. This guide covers version 1.1.0.

A nest can include woven twigs and grass, a coiled rim, soft lining, a mud cup or mud pellets, moss, lichen, leaves, feathers, string, eggs in 8 patterns, and a support such as a branch, a wall or the ground. Everything is shaded with 16 procedural materials, with no image files.

It works in Blender 3.6 to 4.x, and installs as an extension in Blender 4.2 and newer. It needs no extra Python packages.
