|
|
So the best edit approach is to <i>erase</i> the secondary data and let the system automatically regenerate it on edit completion.</span>
|
|
<p>You can also <i>keep</i> all the data, but you won't be able to change the coastline.</p>
|
|
<p>If you need to change the coastline and keep the data, you may try the <i>risk</i> edit option.
|
|
The data will be restored as much as possible, but the coastline change can cause unexpected fluctuations and errors.</p>
|
|
<p>Check out ${link("https://github.com/Azgaar/Fantasy-Map-Generator/wiki/Heightmap-customization", "wiki")} for guidance.</p>

<p>Please <span class="pseudoLink" onclick=saveMap(); editHeightmap();>save the map</span> before editing the heightmap!</p>`;
