=== Rock Blocks ===

By default, zones will always stretch to cover the entire non-underground area of the map. RMG proceeds in two steps. First, zones are laid out without forcing all the space to be occupied. At this stage, zones tend to have regular, circular shapes, and do not cover the whole map: there are usually unoccupied cells next to the border and at the corners of the map. In a second step, all unoccupied cells are claimed by the nearby zones. As a result, these zones may expand significantly, regardless their size setting. When "rock blocks radius" option is enabled, some of the unoccupied cells are filled with obstacles, so they do not contribute to extend the playable area of the nearby zones. It results in zones that are more uniform in size and shape. The "rock block radius" setting controls the relative radius of the playable zone. Default value is 1.0. The smaller the value, the more cells are filled with obstacles, resulting in smaller playable zones, but with more regular shape. However, if the value is too small, the option will be automatically disabled.

For underground zones, a similar algorithm is always enabled, with a radius of 4.0. This value will be overwritten by "rock blocks radius" value, if enabled.

For templates with water content, water will be generated instead of obstacles. Water zones are not affected by rock block radius option.

Rock block radius can be tuned, by trial and error, to adjust zone sizes and/or zone size ratios. Note that a radius value will only be suitable for a given map size and a given template structure. If you change these, you may have to manually adjust the radius again.
