Hi,
I am new to after effects and have an amateur question for you, as always.
I have created an animation in maya with black background, imported it to AE 6.5 and have put keylight on it, choosed the color picker clicked on the black background but nothing happened, the black background is still there(i switched on the transparency grid).

"Better yet... go back to your 3D app and render with an alpha channel or at least generate a matte to do a track matter with"
I dont know how to render with an alpha channel or generate a matte.
Can you tell me how to do it or where can i find documentation on it?
I am using maya 2008.
Thanks for the responses.

Or try using a luminance key. Not ideal but will work on your black background. Ideally the exported video would have an included alpha channel. Look at exporting to a mov with "millions of colors +" as your color choice.
