i have a 3D Object and want to add a background image( if possible even a movie) to this 3D Object. I use Cycles to render and tried a plane with the image as texture. When i go into render mode, it looks like this(picture with background) and when rendered, it has no background. The key also looks into a different direction.
Should i even use Cycles for this or use motion tracking? i tried to use that but had several problems.
When scene is rendered
