This is something I've been dying to find out for a long time. I tried to figure it out myself once, but got stalled at getting the arbitrary map into AE. I'll give it another shot, but if anyone knows how to do this would they mind sharing?

Okay, so I played around with it a bit more and figured it out.

To get the Arbitrary Map out of PS you have to go into curves and set it up as you want it (arbitrarily... of course). Before you click the 'Save...' button make sure that you have the pencil tool selected in the Curves dialog. If you Save without the pencil tool selected then it will save a curves (.acv) file, when you select the pencil tool it saves an arbitrary map (.amp) file.

Now, the confusing part was how to get this file into the Glow effect in AE. The AE documentation says that when you select the 'Arbitrary Map' option a standard 'Open' dialog should pop up, but this doesn't happen... unless you hit the 'Options...' button of the Glow effect. When you hit 'Options...' you get an Open dialog that will allow you to select any Arbitrary Map (.amp) files.

Note: I tried saving out an .acv file and renaming it to .amp but the Open dialog in AE wasn't fooled.

Glad I finally figured this one out, hope this helped.
