Another important thing to remember when creating your own Textures is to maximize the space within the Texture itself when you're combining multiple images. However, be aware of different materials requiring different parts of the same Texture. You can end up using or loading that Texture multiple times. In addition, some Textures may also have an alpha channel, which makes part of the Texture transparent. Lastly, for parts of a texture that are tiled, you don't need to add the image tiled more than once. In general, you only need the part that is tileable; Unity will take care of the rest. Not only will this help to increase the resolution of a tileable image, it will also save space. Fortunately, there are a few programs out there that help to make this whole process easy, such as TexturePacker, which you can find by either visiting https://www.codeandweb.com/texturepacker/unity or by scanning the QR code:
