I'm on a project where I need to load external sprite sheets for the main character, and because the player can choose between thousand of them, I can't really use the built-in sprite strip importer...
Here is the upgraded sprite component I need:
To do this:
Then I just have to load images from URLs into the sprite, and change the "Crop origin" parameter through events to create my animation from scratch.
If you follow the link I posted above, I made a working prototype using an animated "mask" with blend modes instead, but it's not that good for performance, and adds a bunch of problem with layer ordering.
Now I don't know if this is possible with a plugin, but it could be quite powerful for a few other stuff, like loading enemy sprites as the player progress through levels, or opening new animations possibilities
