When should I regenerate an entire map instead of using the Brush Tool for specific changes?

The decision to regenerate an entire map versus using the Brush Tool comes down to the scale and nature of the changes you want to make. If you're looking to make minor adjustments, add small details, or modify a specific, localized area (like changing a door, adding a chest, or altering a small patch of terrain), the Brush Tool is your best friend. It allows for precise, surgical edits without affecting the rest of your carefully crafted map.

However, if your vision involves a fundamental transformation of the map's overall layout, perspective, or environment, a full regeneration is often the more efficient and effective approach. Think of it as starting with a fresh canvas for a completely new scene, rather than trying to repaint a small section of an existing masterpiece.

For example, if you want to shift the primary geographical features, drastically alter the map's theme (e.g., from a lush forest to a barren desert), or change the overall structure of a building, regenerating the entire map will give the AI the freedom to create a cohesive new design from scratch. This prevents the AI from trying to force new elements into an existing, incompatible structure, which can sometimes lead to less satisfying results when using the Brush Tool for very large areas.
