Sorry to join this conversation so late. I too find the asset management a bit of a hassle, but nothing unmanageable. As for the problems that [USER=“35245”]Yuji Saeki[/USER] seems to be having, let me ask you this: is your OS in English or another language, ex Japanese? I’ve stumbled upon some nasty problems that are simply caused by unicode characters causing all sorts of problems in a folder hierarchy. This might explain why moving marketplace assets causes crashes. This almost never happens, because the assets that have just been added aren’t referenced anywhere yet. My advice is to use an English distribution of the OS for Unreal development. It’s not ideal but it is safer!
