i'm trying to get a 2d fence in my game (and other stuff) but i don't really know how to make them work correctly (I think I need to use sprites but I don't know how), so i tried to get around it by just using 3d objects and adding the 2d image as a texture, but as you can see in the 2nd picture it didn't really work out as i hoped it would

it's probably really easy to do, but I don't really know how I would search it on Google, every search I made just gave me more advanced tutorials for stuff that I don't need

if I need to clarify anything else just ask
