I am trying to add an image to a scene to be rendered. I am able to add the image in the compositor, but when I try and render the scene the image is mostly white with a few random pink and purple colors. I am using blender 2.79

This is a screen shot from cycles:

This is a screen shot from what gets rendered:

This is a screen shot from the 3D View camera view:

What is causing the render to be mostly white?

  • $\begingroup$ Is the image the same size (in pixels) as your blender scene? $\endgroup$

  • $\begingroup$ I'm guessing that your camera is way to close. With you cursor in the viewport press "0" to see your camera view. $\endgroup$

  • $\begingroup$ @Dontwalk While in node editor if I push 0 nothing happens. If I switch to 3D View and push 0 I do not see anything. If I switch to render view and push 0 nothing happens. $\endgroup$

    $\begingroup$ @Dontwalk the image is in the compositor, not in 3d space. $\endgroup$

The image you are loading and the blender scene are not the same size (in pixels)

Blender will not auto-size your images to fit within the compostion.

To know how big your image is press N in the UV/Image editor to bring out the side panel.

enter image description here

If you load an image that is larger than the composition, you will only see a portion of the image.

enter image description here

If you add a scale node and set it to fit, then your image will be scaled to fit within your composition.

enter image description here

Note that if the images are a different aspect ratio than the output, you have three choices:

stretch: deform the image to match within the aspect ratio of the container)

Fit: keep the images proportions but fill the remaining either with a transparent background or with black (if the "Use Alpha" option is unchecked)

or Crop Not stretching the image, resizing to fit vertically center cropping horizontally.
