Could you upload the scene? Also, is there a link to this tutorial? And in a Windows environment, the default place Maya dumps the crash logs is the "C:\Users\Username\AppData\Local\Temp", using the naming convention MayaCrashLog(can't miss them ). I dont know why i haven't got any crash logs at that location you directed me to ... but anyways i sent you my maya file (not sure if it's uploaded properly through simplymaya or not, i can put a 4shared file for you too just in case). Thank you for helping me edit: hold on i'll upload to 4shared i dont know where my maya file went ... https://www.4shared.com/file/Kq5wqxN8/Tree_file.html
