I’m trying to do a composite rendering using the pytsai script. Camera match worked quite good and in camera view everything is properly arranged to my backgroundimage, but when I render the image, the background image disapears. I’ve looked through the manual but didn’t find a easy way to get it rendered. It seems this can be achieved using nodes, but I’m quite new to blender and got no clue how to use them.
Another question is how an objects shadow can be rendered on a plane, that itself should be invisible. ( I matched a photo of my desk to a plane and now I want to add some objects. the plane should become invisible and the shadows casted on the photo)
I hope I made my intention clear and someone can help me, otherwise I could add some screenshots
