I've tried adding all sorts of lights (spot, parallel, ambient, point) and they appear just fine in my layer hierarchy and in 3D space BUT they do not emit any actual light. They do not "shine".
I have made sure to check that the items I am trying to shine on are in 3D mode, Draft 3D is on, etc, etc...
I am using AE CC, latest version. Using a PC, Windows 8.1 64-bit OS, i7-5500U (2.40GHz 1600MHz 4MB), NVIDIA® GeForce® 840M 2GB graphics.
My lights were working when I first started using them weeks ago, but for some reason they have stopped...
Draft 3D is on, etc, etc...
Try turning that off.
You should see the light lighting up the solid.
If you don't then your composition panel settings are wrong. You should have Draft 3D turned off and resolution set to auto, zoom factor to fit up to 100% or less and your view set to active camera and your fast previews set to final quality or adaptive resolution.
Thank you so much!
