  Bottom of the stack vs ambient light

  Posted by Philip Hogarth on August 6, 2011 at 9:49 am

  Hi people,

  I have not used After Effects a lot before and not regularly but I have got a problem concerning ambient light. I am doing a 3D project which includes a basement which leads to stairs connecting to a city. I have used an ambient light for the basementhowever I have had to place the city at the bottom of the stack otherwise the view is wrong. Because of this the city falls under the ambient light as well. I have tried to precomp the basement and add the light to this but it doesn’t recognise the light and the walls are greyscale. I was wondering if there is a way to stop the ambient light affecting the bottom layer.

  Thanks,

  Phil

  Turn off the “accepts lights” property of the 3D layer?

  I tried that and there is no change, I also tried turning off the adjustment switch but this has no effect on the composition whatsoever.

  Hmmm … I’m on a laptop without AE at the moment so I can’t check … maybe I recalled wrong and “accept lights” doesn’t apply to ambient lights or something … sorry.

  Not at all mate, just grateful for any help. If I precompose the basement layers and add the light in there it fine. Then when I go back to my main comp it is correct until I turn on the 3D layer switch and it goes back to greyscale. Thanks though.
