The unit of measure for patch position is 4 meters, so that's enough for a 256x256 meter region, but not enough for larger regions. So, there is also a terrain patch layer type &quot;M&quot; (AuroraLand in Firestorm viewer). In this format the position of the patch in the region is two 16-bit fields, in [y,x] order.</ins></div></td></tr> <tr><td colspan="2">&#160;</td><td class='diff-marker'>+</td><td style="background: #cfc; color:black; font-size: smaller;"><div><ins style="color: red; font-weight: bold; text-decoration: none;"></ins></div></td></tr> <tr><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"><div>===Cloud Patch===</div></td><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"><div>===Cloud Patch===</div></td></tr> <tr><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"><div>===Wind Patch===</div></td><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"><div>===Wind Patch===</div></td></tr> </table>
