I'm following a book on character creation in Blender and I'm currently trying to composite my character within real footage through camera tracking. I'm at a part where I'm trying to set up the character and its shadows in a separate Render Layer and adjust them through Nodes. However, in the book, the two Render Layers have a transparent image showing. They're not showing for me. Also, adjusting things like the RGB curves has no effect. Have I set this up right? Or have I missed something?

enter image description here

Thanks

    Not all questions need the file. It is easier to find answers if you post images showing the nodes you are using in the compositor. Use the tools from this site to upload images so that they appear as part of your question. See How to upload an image to a post?.

  • Nope, I don't have a transparent object. The object appears in the footage fine. It's the Render Layer image that should be showing something and it's blank. – DustyShinigami Feb 18 '19 at 18:00
  • No pictures for us to show the issue? –  Feb 18 '19 at 18:02
  • Okay, so I think the issue was, was that I needed to do a test render, and then transparent images appeared. However, the one for the character's shadows don't. I've still yet to add the rest of the nodes from the book, but I'm pretty sure the shadows should be appearing within the image. – DustyShinigami Feb 18 '19 at 18:49
  • For those more serious about compositing into footage, I’d recommend Paul Chamber’s excellent series http://www.paulchambers3d.com/blog/2017/8/22/adventures-in-scene-referred-space-part-one as well as Sebastian König’s post which tackles similar issues http://blendfx.com/working-with-blender-and-the-arri-alexa/. – troy_s Feb 18 '19 at 19:12
  • You need to render something by pressing F12 or pressing the render button, so that the compositor has information to work with. Read: https://blender.stackexchange.com/a/6436/1853 –  Feb 19 '19 at 01:25
  • I’ve set up all the nodes now from the book, but the shadows won’t show. I’ve rendered the scene with F12, but only the character shows. I have the character on one Render Layer and the plane he walks on on another. I’m working in Cycles, by the way. – DustyShinigami Feb 19 '19 at 01:42
