In Node Editor, I have selected Compositing, Use Nodes, and Backdrop. In the tutorial I'm using, the object image shows up on the Render Layers Node, but it doesn't on mine and I can't get the backdrop. Can someone tell me what I might have done wrong? This is v2.76, Blender Render.

Edit: Here is the tutorial, Simple Energy Effect. Node work begins at 9:25.

As soon as he clicks 'Use Nodes', the left box has the image that will be on the backdrop when he clicks that button. My Node box has no image in it.

  • Pixelfoot, it would be helpful if you would edit your question to include a link to the tutorial. – brasshat Jun 16 '16 at 5:54

The small preview displayed in the render layers node is only visible after you have first rendered your scene. The preview can also be hidden by clicking the little material circle at the top of the nodes.

render layers

The image displayed as the backdrop in the node editor comes from the viewer node. This is also not available until the scene has first been rendered.

viewer node

You have to connect the output of the node you want to see to the Viewer Node for the image to display in the Backdrop.

Try rendering once, or moving to a new frame
