Thank you for your answer. Yes, I've looked into this folder before I asked here, but no texture resembles the buildings at Juno, Einbroch and Einbech there. I noticed that they were using specific abbreviation for each city, e.g "prt" for Prontera, " "jp" for Amatsu, etc. But for juno, einbroch and einbech I could only find them outside the texture folder, with file naming as einbroch.gat, einbroch.rsw, and einbroch.gnd.
