Memos & notes on everything in Blender, from objects to keyframes

Open a Blender project after three weeks, or someone else's, and you still know why that modifier is there, what the next pass on the walk cycle should fix, or which material is the final one. PolyNotes lets you write notes right on the things they're about. Each note remembers the view and the frames where you wrote it, and takes you back there in one click.

Requires Blender 5.2 or later.
