Saving problem

Hello everyone, I’ve placed a live video on a plane in Unreal Engine, set it up to loop continuously, and it always plays on the screen. However, when I save the files, close Unreal Engine, and then reopen it, the video material is lost. What could be causing this issue?

Hey there @tennnshu! Does the material asset itself disappear as if it was never created? Or does the reference to the media disappear?

Thanks for replay,
Only material disappear

That is… interesting. Are you saving the material in a folder managed by the engine or anywhere outside of main content?
