I’ve been working with blender for a while, and I tried to do something I thought that would be extremely easy. All I want to do is open one of my saved pictures in blender, add in a few mesh, and render it. It sounded easy to me, but I was stumped when I attempted it.
Does anyone know how I would go in order to do this? I tried just importing the picture as a background so I knew where the meshes would go, and then I would render the image and then combine the 2 images together. But the problem with that is that the picture with the mesh renders the world background
Set the World texture to be your background texture
Use the compositor to combine your render and an Image Input node
Use some external application to combine your image and render. For the render you would need a transparent background so ensure to set an image format that can do this such as .png, set it to RGBA so includes an alpha channel and in the Render / Shading panel set the Alpha to Sky (Blender Internal renderer) or enable Transparent in the Render / Film panel (Cycles Renderer)
Use the Image as Planes addon to import your image on a plane. Make its material shadeless, put your camera and object in front of the plane and press Render
Ahhh!! Thanks sooo much! Since I have no clue on how to composite, and clicking prferences to go onto the addons crashes my blender, method 1 and 2 work the best for me! And I think for method 2 you mean set the Alpha to transparent? But yeah man, thanks. This really works!
