This script will copy the movements of a 'leader node' and apply them to a 'follower node'
but ... and this is important, with a delay.
in the example shown above, the leader node is Aiko's hip node
the skirt is an object parented to Aiko's hip node ( free!, created by me, see conedress1536ruffled.obj in the attachments )
the follower node is a D-Form influencing the skirt
as you can see below, the D-Form is positioned at the bottom of the skirt
so the influence is maximum at the bottom and nil at the waist line
After using mcjLagEffect, when the hips twist, the D-Form (and the skirt) also twists, but ... a few frames later.
download the zip file in the attachments at the bottom of this page
unzip it in Daz Studio's content folder
typically C:\Program Files\DAZ\Studio\content
the script and the corresponding icon will be placed
in the scripts/mcasual folder
so you can find it in the Daz Studio content tab
in the Studio / Scripts / mcasual folder
there's also a zip file containing the manual
which is simply a copy of the page you are reading
we have a stretched cube which is the parent of a 'Null' which is the parent of a cone
the null is below the cube and at the tip of the cone.
Select the 'follower' node
in our example, the Null node
by default, the leader node is the immediate parent of the follower node, in our example, that's the stretched cube.
if you want a different leader node, press and hold you keyboard's CTRL key while selecting the desired leader node.
Here is mcjLagEffect's user interface
1 - select the range of frames to be processed and the keyframe step
If you want to reduce the number of keyframes created you can set the "step" value to, for example, 5.
The movement reproduction will be less faithful, but the load on the daz scene will be lighter.
2 - select what part of the movement will be replicated
in the case of the skirt, we only replicated the "orientation", meaning the twists and sways and tilts
3- enter the desired delay/lag
by default the follower will lag the leader's movements by 5 frames,
at 30 frames per second, this means 1/6 second
4 - click the [ Do it ] button
processing should take less than a second
here's the Orientation-only lag effect
