I just started seeing an issue where the editor hangs for nearly a minute on the “Building Texture Streaming” during level build.
My level is pretty much just a grey box with almost no textures used. It’s also worth noting it becomes unresponsive during this time and I cannot press the “Cancel Build” button. The Task Manager shows very little usage.
Over a minute?!? Seriously? Oh no, it’s the end of the world… lol Ok. Yeah, what you’re facing is normal. One minute is nothing. It’s normal even if you don’t use any textures. Just wait. A quarter of the development life is waiting the computer.
