I am in the middle of implementing Runtime Atlasing through the RenderTexture method described in this thread (
http://2dtoolkit.com/forum/index.php?topic=4219.0 ). However, I am having trouble with the part where the sprites need to be packed into the view of a camera. Namely,
1) In what way should the sprites be rendered? Is it through Texture2D?
2) How do I pack the sprites into efficient positions?
I am sorry if these questions are obvious, but I have been stuck on this problem for quite a while and even implemented the feature through Texture2D.PackTextures, however its performance is simply not efficient enough for what I need.
