  Value of motion blur switch into an expression

  Posted by Paul Roper on February 5, 2013 at 1:36 pm

  Hello,
  I would like to access the value of the motion blur switch on a layer, something along the lines of:

  thisLayer.motionBlur

  …so I can control whether Motion Blur is / is not applied in the Refine Matte effects for that layer. I can get the comp’s shutter angle easily enough (thisComp.shutterAngle) and poke that into the Refine Matte effect’s shutter angle, but it would be very useful to be able to get a per-layer motion blur enable/disable property kind of thing.

  From dragging the pick-whip to any of the layer’s switches (which achieves nothing) it seems I might be asking for the impossible, but I’m hoping it might be hiding as some obscure variable stored internally that I can grab.

  Any help would be greatly appreciated!

  Thanks,

  Paul

  As far as I know, you can’t get at the motion blur state.

  I suspected as much. Thanks (as always!) Dan.
