It works in Blender, so you should be able to get this working in<br>
After Effects too. I'm not familiar with AE or what kind of setup you<br>
created there exactly, so I can't make any specific suggestion for how<br>
to fix it.<br>
<br>
But as far as I know, the way Cycles is storing these passes is<br>
similar to other renderers (for example V-Ray), so I see no reason to<br>
change it.<br>
