I just found out that the images are measured in pixels in RAM that has nothing to do with whether it is optimized to occupy less memory or not, something is always learned.
I have been told that I can make the parallax the size I want even more than 3840x3840 and then divide it into sections, these sections put them in the plugin in this way the game does not have to load at once 3840x3840 or more, but only the section in which it is and it will load and unload in memory the section that it needs at all times.
But when I saw how the plugin was used in the example project, I saw that the parallax layers had to be all the same size as the map, for this reason I can't get it to work on larger maps.
Can you tell me if this is possible with your plugin? Well, the only way I see to load the parallax in the plugin is that the image has the same size as the map.
