I use Cycles, (I think, because all the videos say it's Cycles and 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 model's for a game I'm making. Please help!
