I am having trouble creating 3D text when it comes to adding the light layer effect. I write the text, create a camera, make sure the 3d button is checked, and extrude the text. Then I move the text to see the new 3d angles of the text. As I create a light layer, nothing shows up on the text. I have made sure that I am in Ray-Traced 3D mode, but nothing happens. Help!
Show screenshots of your Composition panel and of your Timeline panel with all of the relevant properties expanded so that we can see them.
Your comp is set to Draft 3D in the timeline buttons, which simply ignores all lights. Turn it off and it will work just fine.
