After I get back from my vacation I'll post new converted grounds from PES6. I'm planning to make all of their J-League models (except the Tokyo Olympic Stadium which is currently renovated), but unfortunately I encountered some missing parts after exporting. I have this issue in Yokohama and Sapporo, which is a shame, especially in Sapporo, which looks awesome in overall. Maybe somebody could help me with fixing this bugs. :P
Anyway, here's some previews (in-game and blender ones)
Kashima Stadium (Kashima Antlers) 100% ready
Big Eye Stadium, Oita (Oita Trinita) 100% ready
Kincho Stadium (Cerezo Osaka) 95% ready
International Stadium Yokohama (Yokohama F. Marinos) -you can see what's missing... the ground will be fixed, but the rest is just missing
Denka Big Swan Stadium (Albirex Niigata) w.i.p.
Sapporo Dome (Consadole Sapporo) - missing exits on second condignation (export bug)
Yamaha Stadium (Jubilo Iwata)
Fukuda Denshi Arena (JEF United)
