motion blur is disabled

I've been making changes to someone else's AE file with a lot of layers that have motion blur. I've changed positions of many of the objects, and now there isn't motion blur in many places where there was before, A great many layers have a hyphen in the timeline's Motion Blur box instead of the Motion Blur icon. And there doesn't seem to be any motion blur in those layers.


When I click in a box with the hyphen, nothing happens. In the Layers menu, Switches>Motion Blur also doesn't do anything.


Please-- what is happening? Is AE telling me I don't have the resources to do this, maybe?


I'm using a MacBook Pro  2.8 G with 4 G of RAM, OS 10.6.8, and After Effects CS 5.5

    Are they hyphens on pre-comps?


    That hyphen usually means that you have a pre-comp with transformations collapsed.  That's the switch with the little sun-lookin' thing on the pre-comp layer.  Don't mess with that unless you're familiar with how the layers are set up or you might mess something up.


    Enter the pre-comps and enable motion blur on the individual layers.


    Making any sense?

    This has nothing to do with resources. You have pre-composed stuff or used combinations of blending/ matte modes. All the hyphen tells you is that any pertinent switches will have to bbe set in the pre-comps and/or you may need to restructure your project to get motionblur.

    Just putting in some Hold keyframes wouldn't have this effect, would it?


    Exactly the opposite: Hold does what it says - it does not interpolate, hence no motion blur. And again, those hyphens mean that switches/ settings are inherited. Fix the pre-comps and the motionblur wil lrender just fine. If that's not possible, try things like CC force Motionblur or comemrcial tools like RSMB to introduce artificial/ forced motionblur.
