You need to load your map in Map Maker then hit the Export button. All your exported filse will appear in YOUR export folder within the Feralheart folder.
Files include .fhm (the map itself), .fho (the object groups you used), .fhs (the sky you used), .fhw (the weather cycle you used).
All these files need to be found and put into a compressed folder. Then upload that folder to a file sharing site such as mediafire or zippyshare ect.
Give your friends the download link, once downloaded they need to place the files into their exports folder. Then the map portal will be in Cape.
