I have to resurrect this thread because I had a similar case today. In the comp of a project where there were a bunch of comps, just one comp had its light layers stop working. I had a save of the project where the lights would be working so I imported it open the comp where the lights worked copied all the layers and pasted them in the comp where the lights would not work (before I deleted al the layers in there)
and guess what, the lights would not work again… I finally copied the comp and replaced the whole comp and then it did work. The only suspicion I have is that this was a project converted from CS4 to CS5 other than this I wouldn’t guess coz I checked everything and having worked with AE for more than 15 years I know quite a bunch of tricks…
Any Idea?
(we’re at a thousand miles from a “3D layer switch on or off” issue here, I guess…)
