So I have a lot of questions on this topic. I am trying to make a top down 2.5D space shooter. Now my main question is what would be the best way to make the background of the level for this type of game? Should I create a plane and put what I want the background to look like on that plane as a material, maybe a space skybox, or maybe there is some other way to do it that I have yet to figure out. So please let me know. I am open to all ideas and suggestions :).
Thanks in advance! 
I’m making the same kind of game, and what i have decided to do, is use a plane with the desired background texture.
I think this is the better option if you want to keep things simple (and also is very cheap in resource consumption).
See ya!
What size plane are you using?
My texture is 512x512 pixels and i have its plane is currently scaled to 256x256x0.
Also, i have tested making the background scrolling by setting a panner in the material, but i have to research how to set the panner SpeedX and SpeedY properties from BP system in order to be able to dynamically change them.
See ya!
Cool thank you for the help!
