Can I do progressive load before packing?

  @speeder_kidoteca unfortunately texture loading is not assync and although it is in our roadmap, efficient implementation in our current system would be quite complex, as all works on a single thread.
  
  So even with coroutines, if file is large enough, it will freeze the gameplay.
  
  Most common suggestion is to preload all the files on the beginning of the scene.
  
  You can either create a static packed texture (using Texture Packer) and load it on scene start.
  
  Or load all separate files by creating Texture instances for them and storing as scene properties and use them later (you can even create a loading bar and update it between loaded textures this way).
  
  But unfortunately these are the all available options for now.

  I think you ALMOST understood me.
  
  I know large enough files will freeze things, that is my point, I want to load smaller files, one after the one using coroutines, instead of loading a large file.
  
  For memory efficiency reasons, it would be awesome if I could load those files separately, and then pack them in memory using maxrects.

  Aha, I see.
  so you want to know the progress of loading texture separately, but then also using all the perks of packed texture
  
  Unfortunately yes I don't think it's possible yet.
  While you could load all the graphics separately and then try to create the dynamically packed texture like this:

  local pack = TexturePack.new({"1.png", "2.png", "3.png", "4.png"})

  I don't think it will reuse the loaded graphics from memory, because they way it dynamically creates a pack differs from a standard texture loading way.
  
  So currently your best bet would be to create static preloader:

  or load separate files.
  
  As loading separate file may turn inefficient and won't provide smooth animation, I would go with a static preloader
  or even integrate it with SceneManager to appear automatically with every scene:
