a flipbook is the only thing that comes to mind
you could also use a scene capture 2d to record the animation as it happens somewhere in the level but i’m not sure that would be any cheaper than importing a video.
I came across this animated screen and I’m wondering about the best way to create something similar. I believe I can do it by using media framework – creating the animation, importing the media and adding it as a material to a plane. However, this seems resource intensive. Is there a better way to do this?
