  • radio waves..is this the right tool for the job?

    Hello All,

    I am trying to creating a series of circles that start small and grow larger (like the circles created with the radio wave effect) but I need the circles to be solid and I need 3 different shades of orange. Meaning that the first circle is one shade of orange it starts small and grows large, then the next circle is a different shade of orange starts small and grows large, ect. This can repeat forever. I also need these expanding circle to stay confined within a vector drawing (an image not type) imported from illustrator. Anyone have any suggestions?

    Thank you,

    H

    Sounds like three different layers of Radio Waves.
    But the method in use will depend on what you need that RW can’t deliver or that you can’t get it to deliver. A single circle can be turned into a replicator source. See Layer Shapes in the manual. It’s tedious but easily done by adding a REPEATER to the animation stack.

    Confining your radio wave effect to a vector shape should be a simple matte process but you haven’t said what that shape is.

    This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

    Ahhh, thank you Boglesan! That’s great advice! I’ll fiddle with the repeater now. The shape that will be confining the circles is a groundhog I drew in Illustrator. Do I need to redraw a mask that confines the circles inside the groundhog or is there a way to use the vectors from the original drawing?

    THANK YOU!!!!!!!

    Use the original drawing a layer above, do some crazy levels on it and desaturate to make it black and white, and then use a luma matte.
