Using Unity's 2D tools for the first time and there is a snag that I can't find the answer to.
Here you can see a very simple test texture atlas, however for some reason the only shape I can work with is a rectangle; I can't even rotate it. I am probably missing something simple, because if the only shape I could use for for a Multiple sprite sheet is a rectangle, then it would simply be a better option to use polygons with textures instead of sprites.
I asked a friend that uses Unity a lot and he told me to load each image in on its own and then to use the Unity sprite packer, however a quick test proved that the sprite packer wastes a lot of space.
Is there a way to use a shape other than rectangle or to rotate it?
