Stellar Sprites is a dynamic and powerful sprite generator. It's extremely easy to use resulting in countless unique sprites.
Do you need space sprites? Whether you are creating a Space Shooter, Adventure, RPG, Trader or any other type of genre, Stellar Sprites has you covered. Drag a prefab of a ship to your editor window and everytime you run your game, that ship, planet or whatever it is, will be brand new. If you find something you really like, save its seed or click the Save to File button and use it later. Stellar Sprites can also just be used to generate sprite files (.png) and you can fine tune them to meet your needs.
Compatible with Unity 4.3+ and Windows ONLY until 1.3
(Although not tested, if you were to modify the included scripts, you could use it with pre-SpriteRenderer versions of Unity)
