/*
|
|
* For building atlases at runtime it is very important that:
|
|
* - textures be in trucolor/RBGA32 format
|
|
* - textures have read flag set
|
|
*
|
|
*
|
|
* It is also Highly recommended to avoid resizing
|
|
* - build padding into textures in editor
|
|
* - don't use padding when creating atlases
|
|
* - don't use tiled materials
|
|
*
|
|
* If you are having problems look at the Debug Log on the device
