Sometimes, when I go to import a new asset into a project, I’ll click import button and Unreal will just completely freeze and won’t accept mouse events. Literally, if I click on editor window, window behind it will receive touch event. This can only be remedied by forcing Unreal to quit and re-open it.
This actually happens quite frequently. For instance, if I leave Unreal open for a few hours while I’m away and then attempt to import something, this always happens. It may also happen after importing 2 or 3 things in succession and attempting another import.
I haven’t been able to reproduce this behavior. At what point does editor freeze? Is it right when you click Import button, or are you able to select file to import? If latter, are there specific types of files you are trying to import that cause problem? Thanks!
Sorry for delay in response. Without a reproducible case on our end, it’s going to be very difficult to be sure, but we believe this may have been fixed in a recent change made which will probably appear in 4.7. Once that preview becomes available, please attempt to reproduce import problem in a new project and let us know if it still occurs. Until then, please let us know if there is any additional information you believe may be relevant. Thanks!
Additionally, next time this happens please double-check to see if a crash window appears behind main editor window. There are some known issues in which that happens, and we may be able to attain more information from you if that is case.
