What kinds of major layout or environmental changes are best handled by a full map regeneration?

Full map regeneration is ideal for scenarios where you need to fundamentally alter the core elements of your battle map. This includes significant shifts in the biome or environment, such as transforming a snowy mountain pass into a volcanic wasteland, or a bustling city street into a ruined, overgrown ancient site. These changes impact the entire visual language and structural components of the map.

Beyond environmental shifts, consider regeneration for major layout overhauls. If you initially generated a map with a river running through the center and now need a large, open plain, or if a small cave system needs to become a sprawling underground dungeon, a full regeneration will allow the AI to re-imagine the entire space. Trying to achieve these drastic changes with localized inpainting can be cumbersome and may result in disjointed elements.

Essentially, if the change you envision would require the AI to rethink the map's foundational structure, its primary features, or its overall 'feel,' then a full regeneration from a refined prompt is the most powerful way to achieve your desired outcome. Don't be afraid to experiment, as Version History ensures you can always revert if the new generation isn't quite right.
