Botched Baking by Beginner

No.524367 ViewReplyOriginalReport
Good day everyone,
I hope this isn't too sophomoric a question, but I'm trying to set up a simple light box in Blender. Purpose is to create some baked UV layers to utilize for creating more more effective textures. I'm having a great deal of difficulty following the guides and youtube videos searched through google, was hoping one of you could point out what I'm doing incorrectly.

So, in Blender Render mode, I'm able to get a factory-default bake just fine. My scene currently has one sun, an object, and a plane underneath. However, I want to lighten the pitch black bottom with some sort of reflection from a ground.

Image attached is what I'm currently looking at. Do you see any steps I've missed when switching from the basic Blender Render to Cycles Render?
