  white border in composite

  Posted by John Slately on April 19, 2011 at 8:56 am

  I have a series of PNG images (character and background) rendered out of Autodesk Maya (with Mental Ray) for compositing in AE.
  They are the DiffuseNoShadow, Indirect, and Shadow pass. Premultiply was disabled.

  I imported the sequences into AE, initially ‘Straight’. For a foreground character, I screen the Indirect pass over the Diffuse in it’s own comp, but notice a dark border. Interpreting the Indirect layer as being ‘Premultiplied’ fixes things somewhat, but leaves traces of a faint white border.

  I would add a ‘Matte Choke’ to remove it, but since the layers have a “holdout” (from mental ray) doing so would create a black where the pixels were choked. Also there are some narrow areas I can’t choke as they’ll be removed.

  Anyone have a solution to my border issue? My appreciation if you do!
