  • Writing an expression for distance-based opacity

    Posted by Mostafa Talebi on November 16, 2011 at 3:52 pm

    I have a trapcode particular layer.(snow simulation);

    I want the snow’s individual particle to be smaller relevantly at near distance to camera, and those smaller at relatively further distance.

    What should I write?? (I know how to write it with mel, but not of course in Java)

    Thanks

    Particular’s particles are already camera-aware. If your scene has a camera, the particles nearest the camera will appear larger.
