Renders doesn't display in Node Editor while compositing I follow that tutorial step by step:
https://www.youtube.com/watch?v=H3sSZ6W7rgQ
and had to stop around 44:00 - I had rendered my image and when I go into Node Editor there is no way to make backdrop shows up. I don't know what's going on. I'm using Blender v2.71. Please help me :)
TARDIS Maker comment is a solution to my problem, I just didn't connect render layers to a viewer node.
