Hi, how would you composite motion blurred passes with alpha? I get "famous" dark edges around the objects. I've just look a lot for an answer and try out different techniques but I can't find a way. Was hoping to find one in here but I just see the vector blur filter lesson. I understand this is probably too advance for an "Introducing course", but is there any advice on it, maybe even just a different keyword for search an answer? Thanks

    If anyone is checking now, try checking the premultiply button on the alpha over node.
