be careful, though. They won't anti-alias.

my recollection is that you just import em like any other sequence of images.  They'll show as a bright patchwork of colors in the shapes of your objects.  I filtered out individual objects by color and used them as mattes.

my plan for my thesis was to render out a matte pass at a higher res than the beauty pass.  the color was going to be a black and white hold out of the main character (because fur doesn't work well with tags and my character is full of fur).  And I was going to spit out a tag pass along with it.  That way, the fact that the tag pass is not anti-aliased would not be as much of a problem.  I'd scale down that layer in the composite once I had extracted the non AA-d matte.

But if what Matt said is true (I checked my mail archive to be sure I was not confused about what was said) then it may not work on animated sequences.  Which would be a shame.  I'll have to run tests before I start rendering.  But thats months away for me.

Forgive my ignorance with the FX Tree I don’t use it much. I poked around the Docs and the FX Tree effects but couldn’t find much about the Tag files. Do you have to do anything special to them or just import them?
