I am creating a separate (non-Unity-based) product that will allow my customers to generate "project" ZIP files that will contain various configuration files and data displays.
The project will be loaded over the network by a Unity-based app that I am working on now.
Many of the data displays are made up of one or more PNG images (e.g., up and down image for button, background for a numeric display).
As far as I understand, Asset Bundles are not an option because they must be built with Unity, and my customers will only have my app, not Unity.
For now, at least, loading images and displaying them is enough. Performance on an iPad or Tegra-based tablet should be more than enough to handle the extra draw calls for our use case.
In the near future, it would also be possible for me to combine images into an atlas file with a PNG and corresponding data file if that is something that could be handled too.
Thanks!
