Settings > Atlases > Scenes
Primary View: Scenes
- Make sure atlas binding is disabled for all scenes (if you want to strictly use atlases like they were used in the past)
Primary View: Atlases
- For each atlas you want initially loaded, set that atlas to always loaded. When you use the load/unload atlas blocks, this setting will be overridden.
Another strategy is to use atlas-scene binding. It makes more sense and you don't have to worry about loading/unloading atlases yourself. Just bind only the initially loaded ones to your first scene, and for each scene thereafter bind only the atlases you need for that scene.
