Lights Not Affecting Scene I'm new at lighting and texturing, so I've likely done something catastrophically stupid.

Got a relatively simple scene, a hockey puck slides along the ice. Started trying to add some volumetric lighting only to find that none of the textures are receiving light. When I turn Ambient Occlusion on, they all show up at full value. Ambient Occlusion off, everything goes dark.

I'm hoping this is as easy as I've accidentally touched a setting I wasn't supposed to or linked a node incorrectly, but I've uploaded the .blend since I have no clue where to begin with cause/effect on this.



Any help you can offer this despondent n00b would be appreciated.


Blender 2.79b

using the Filmic Blender color management add-on, but I've found
no indication that it's the culprit.


EDIT 08/15/2018: I've discovered a new development. Objects with emission shaders WILL affect scene lighting, but specifically not lamps.
You were only displaying the first layer in your viewport. Make sure to highlight both layers when previewing.
