Resources: Graphic Platform Compression

 This menu is available from some graphics menus such as Sprites and Tile-sets. This option is used to compress graphics which reduces the quality but uses less space. It can result in faster loading times and uses less hard drive space for the trade-off of lower quality graphics.

   

 Atlas 

Padding: Spaces out the rendering of tiles by a single pixel to prevent the edges of neighbouring tiles from being picked up.

 PVRTC (iOS) 

PVRTC is a high loss, fixed-rate texture compression format which is primarily used for mobile game development. Compressing resources is recommended for mobile game development for the purpose of a lower memory footprint, faster loading times and reduced power consumption.

On: Enables/disables the compression.

4-bit: Compresses graphics at a ratio of 8:1 (less compression, higher quality).

2-bit: Compresses graphics at a ratio of 16:1 (more compression, lower quality). Quality: A slider that determines the amount of graphic quality (higher numbers mean better quality but it takes longer to compress).
