TilePlus Toolkit is a system that allows you to have private data in tiles with edit support.
It includes an alternative Tile palette system with support for placing prefabs, prefab palettes, enhanced multiple selection support and “much more.”
TilePlus Painter: a new way to paint Tiles on Unity Tilemaps : a different sort of Tilemap painting and editing tool.
Just like the Unity Tilemap Editor (UTE) you can paint single tiles or groups of tiles from a Palette.
Unlike the UTE, you can paint Prefabs, custom single- or multiple-Tilemap archives and perform complex transform modifications. There’s even a persistent Favorites list.
TilePlus Toolkit: Scriptable and editable tiles that are saved with the scene.
Have you ever wanted to have your tiles actually do some work at runtime? Sure, you can subclass Tile, then and add code and fields to a tile class, but roadblocks emerge.
TilePlus tiles derive from normal Unity Tiles: but unlike normal tiles, modifying fields after painting does not alter the original tile asset. Each painted tile is completely independent of every other painted tile. This opens new possibilities for working with tiles and requires no changes to the standard Tilemap system.
Lots more detail on the asset store page: fully supported and in active development. This system is free and will always remain so.
