  • TROUBLE WITH KEYING OUT! How do you get rid of one colour?

    Posted by Daniel Haskett on April 20, 2005 at 6:52 pm

    Hi there

    Basically what I have done is created a walk cycle of someone in black and white, but because I want to loop it I have saved it as a movie with a blue background so that I can then get rid of the blue background once I import it again. I thought I could do this with colour key but it still leaves bits of blue around the edges of the man and if I put the tolerance up it takes away parts of the man. Surely there is a way to just eliminate a flat colour?

    Thanks in advance!

    Yeah, but it’s only a flat colour up to the edges of the next colour. Antialiasing blends the two colours, creating a smooth edge.

    You should have rendered with an alpha channel to get transparency. Render to a quicktime movie in the animation codec or to a series of TGA files, output module set to RGB+alpha, and millions of colours+.
