Observe the heavy color banding of the image 5. From Unity's Importing Textures documentation: If the platform or GPU does not support NPOT Texture sizes, Unity scales and pads the Texture up to the next power of two size. The program simply loads a texture and render it as a quad. The performance is so significant that most engines (Unity included) will automatically scale all textures to a power of 2. PNG refers to a type of raster image file format that use loseless compression, that makes it popular among its users. I had the same issue and had to not only uncheck 'compress PNG files' option in Project -> Target -> Build Settings -> Packaging, but also uncheck 'Strip PNG text', so that the png conversion tool is not called at all. You can also use these types to read and An acronym for Portable Network Graphics, PNG is a lossless file format designed as a more open alternative to Graphics Interchange Format (GIF). Both color and equivalent grayscale images can be used as reference images or by users at runtime. Using workarounds to create temporary textures which are replaced by these methods, we can specify the attributes and compression of the textures. The file size reduction can often be as much as 60-80% smaller than equivalent 24/32-bit PNG files. Unity has certain default formats set up for each platform, but in some situations you may want to override the default and pick a different compression format for some of your Textures (for example, if you are using a Texture as a mask, with only one channel, you might choose to use the BC4 format to save space while preserving quality).
