    How to evenly space nulls across a spline control

    is there a way to have a series of nulls evenly spaced across a spline control in layout? i'm trying have a series of bones that each target their own null that are easily transformed en mass through a spline control. i hope that makes sense?

    my thinking was if there's a way to get the total length of the spline control, the z position of a null could be offset proportional to the length of the spline. i might be asking too much of lightwave though.

    any thoughts would be appreciated. thanks!

    Workarounds:

    I made plugin Align Items for Layout, and it's part of TrueArt's Modeling Pack, here you can see how it works:

    Select couple items in the right order, and press one of Align Items commands, and they will have evenly spaced positions/rotations/scales. From 1st item to the last item as references.

    If you have (or can convert Spline Control (export path?) to) spline in Modeler,
    EasySpline http://easyspline.trueart.eu has special tool Spline Density,
    which allows to quantize input spline to user defined evenly spaced control points:

    After quantize of spline, you would have to import it in Layout, and use control points as source of position of null item.

    There is an align and distibute command in layout, it distributes all objects between the first and last object position.

    You can also do the old parent hierarchy setup. When you move all objects at the same time they automatically offset each other with a even distance.

    Is there a way to do that without a spline?

    Just parent the nulls ( e.g. 2 to 1, 3 to 2, 4 to 3 etc ... ) then multiselect all except 1st and move them.

    sorry for letting this hang, but what i ended up doing was using "DPSpline Deformer" in each null's Nodal Motion modifier and plugging a scalar value into it's "Covered Percent" input.
