I use Cycles, I think, because all the videos say it's Cycles. Mine looks the exact same. and when I made my background transparent by going to:
Properties> Render> Shading> Alpha, and set it to "Transparent."
I'm pretty sure this is how you do it because I looked up a video and that's what he did to turn on transparent background.
But, my background is black for some reason, and I need it to be transparent because I'm using these models for a game I'm making.
