Hi there. I´ve found a way to add new stadiums and they work 100% without any hack to lua files. I´ve decoded the rendering database. This database includes data related with all stadiums in game. Since new stadiums we add were not in this database they were not rendering properly ( missing sky, wrong time of day, etc ) Well the fact is that we have the chance to add this lines in a file named rendering_patch.cdb DOWNLOAD IT https://www.mediafire.com/?d5c8mfqv6ocv6fu Open it with hexadecimal editor and it´s easy to understand. From offset 0A to 151 you have the data for stadium 269 day version. See that it says stadiumdb/stad_269_1 From offset 152 to 2BC you have the data for stadium 269 night version. See that it says stadiumdb/stad_269_3 To add more stadiums you just copy the same block and paste after that one ( I´ve already added some more WC stadiums in that file ) You paste the block and simply change numbers of the stadium and ready! This file goes in Game/data/ folder and you have to regenerate or remove reference from data_0.big file Finally solved the mistery where the game stores this data Regards!
