Pass Index is not working as expected

Recently I have done a test with the pass index technique that BlenderGuru (Andrew Price) used in his last Logo tutorial. The idea is to separate objects using Pass Index instead of Layers to apply different Compositing settings.

I have created a simple scene (cube pass index=0 and sphere pass index=1), but I’m unable to make the pass index works (Blender 2.64 R51880). If I select pass index 1, I got only white.

This is my settings…


Any idea?

Have you tried plugging the Index alpha directly into the Viewer Node just to see if it’s picking it up at all?

Yes, and the viewer shows a “all black” screen.

Have you solved it yet?
