I remade some files and packet everything.
It has appearance and its mesh.
It has its datatables/ clientregion, enviroment, player, travel
It has a modified CRC_planet in misc.
It has its shader/ui_planet_selcoruscant.sht.
It has is snapshot/coruscant.ws.
It has its string/en/coruscant_region_names.iff
It has its terrain/coruscant.trn and enviroment/coruscant.iff
It has texture/ui_planet_sel_coruscant.dds
And its ui/ui_planet_map.inc for its map graphic and ui/ui_ticketpurchase.inc for the terminal session.
I wrote its planet_manager for its starport and the planet_weather section via server side.
Added .TRE to config.lua and open Coruscant to world.
But failed. can anyone answer me?. Thank you.
