No, I don't know what it is and where I can find it (if you could explain plz). You mean, adding faces to your patch I could have overtaken 500 files and because of that, my game crashs ? Though It's true that it always crash at the same moment after 15/20 faces imported, it sounds a bit strange ! But anyway, whether it could solve my problem I'm up ! So the solution, when I will know where are the "zdatas", would be to destroy some of them to stay below 500 ?
