      Good morning!

      I'm using the Edge Blend Mask in 2 scenes, and my hope is that there would be a smooth cross fade between them. However, when the crossfade begins, the mask sort of flashes on and then it flashes off when the cross fade ends. Please see the video (watch the bottom of the screen).

      It's the same mask in each scene and it looks great when we are just sitting in the scene. 

      I don't want to use a Global Edge Blend, because I only need the mask for these two scenes. I've tried cropping with a softened edge, but it's not as good because I can't control the width of the softness like I can in the Edge Blend Mask actor.

      Any thoughts would be welcome!

      Thank you,

      Hugh

        I believe the edge blend is applied after the scenes are composited, and therefore can't be mixed in this way.

        The only option I can think of is to ensure the same settings for edge blend for both scenes during the crossfade, and then animate the Edge blend values with envelopes after the scene change has occurred. If its possible, a cut rather than a crossfade would tighten it up, but other wise, flow one after the other ( I would need to test, but there is a good chance the values push through only once when the second scene is activated for cross-fade, so you may be able to start the edge blend animation a short while (0.25) after the initialization of the scene).

            So, this worked (in the second scene). It's a 2 second cross fade. Thanks!!

               Great!
              not exactly what I imagined, I though you might animate the 'bottom width' value. Interesting you need to toggle the visible (mental note taken).
