A free and handy little Unity asset to quickly arrange small textures/images to a big atlas texture and save it as a single big png. Or split a texture into multiple small textures (respectively tiles). As simple as that.
Free to use and a part and foretaste of the quality of the upcoming 3D Tile-Map Creator: iG Tile-Map 3D.
- Drag & drop textures into the Atlas- or load images into the Atlas- or import an Atlas- Arrange the textures by drag & drop- Save the Atlas as a single big png- or as multiple tile textures
