  • CC Force Motion Blur is killing my particles.

    Posted by Nate Hanson on March 21, 2008 at 5:04 pm

    1. I have an adjustment layer with CC Force Motion Blur applied.

    2. I have a precomp below the adjustment layer that includes particles generated with CC Particle World.

    3. When the Force Motion Blur effect is on, the particles are so dim I can hardly see them. In fact, on my background which is a wood texture image, they are all but invisible. When I turn the effect off, the particles come back.

    Why is this happening?

    Is there an easy fix, or do I need to generate my particles outside of my precomp (above my adjustment layer)?

    Thanks for any help,

    Nate

    [Nate Hanson] “Why is this happening? “

    Probably because the particles are moving quickly enough that they become very, very blurry. As they blur they become less visible. Try duplicating the pre-comp to increase the opacity of the blurred particles (you may even want 3 instances of it).

    I think you are right about why they are disappearing, but duplicating the layer (3 times) made no improvement.

    I’m just going to create them above the adjustment layer. It looks fine that way. Plus duplicating the precomp changed the look of the other elements quite a bit.

    Thanks for the quick response, Darby!

    Here’s another option, try applying an Alpha Levels effect on the Adjustment Layer after the CC Force Motion Blur and increase the Gamma value. The downside of this route is that all of the other layers will be affected as well, depending on what you’re doing in the composition this may or may not be acceptable.
