    Hello all,

    Well 2nd time of the evening, i guess i’m not in good health;)

    Anyway, i’m trying to find a way to do a true monodirectional blur and/or shadow.
    Basically using a directional blur is going to go on both directions of the axis
    what i’m searching for is some sort of true directional glow/directional blur
    If anyone knows a plugin/a quick way of doing that without resorting to either
    multi layers/masking, please tell.

    Thanks for any help,

    Paul-Kenji Cahier

    I believe there is one in Gen Arts Sapphire. It’s been a long time since I tried out their stuff so don’t quote me.

    A much cheaper way that’s worked really well for me with mono-directional blur for _text_ is to apply Trapcode’s StarShine, then turn the individual lengths to zero for all but the direction I want the blur to go. StarShine really works well for gorgeous blurs, in addition to the whole Starfilter look thingie.

    Our SmoothKit filter set ( $89.95) has a directional blur filter that will start a pixel and blur going to one side of the pixel instead of both sides. Simply apply the directional blur filter and set the “FIlter Grow” parameter to “One side” (from the default of “Both Sides”).

    You can also control the direction at each pixel (instead of a globally applied direction) through the use of an externally supplied image (like a ramp, or the picture itself). Be sure to read the short HTML manual that is installed with the plugins upon installation.

    You can try the demo by clicking on the “Downloads” button on our webpage for SmoothKit:
    The filter set has some other nice filters: a true compound blur that doesn’t give a box-filter approximation like that found in AE. You can blur images without blurring across edges (using our Gaussian Blur filter and setting the max deviation less than 100%. This is how we blurred the face you see on the page for SmoothKit without blurring the hair too much.

    Sweet. A post from literally 11 years ago answered my question!

    Yeah, I was looking for something that would replicate that “long shadow” look that wasn’t even popular when this post was written. Note that the Trapcode effect is called “Starglow” (Shine is a different one.)

    Trapcode, want to make an easy buck? Repurpose Starglow for a “long uni-directional shadow” effect. My only feature request would be to give us a 360 directional controller instead of constraining to Up, Down, Down Right, etc… A “add grain or texture” feature could also be cool. But this is a great way to play around with multi-colored shadow effects.
