I am attempting to follow this lecture. When I get to masking the ground from my scene, I run into a problem. The Render Layers for the Ground Only has lost its IndexOB plugin and I have nothing to connect to the IDMask. I see it seemingly change automatically in the lecture video. That doesn’t happen for me. I have no way of plugging the RenderLayers “Ground Only” into the IDMask. I have included a screen shot of the set up. I am sure it is something simple that I am missing. I should also add that I am using Blender version 2.79a which may make a difference.
Any suggestions?
