 Introduction
This is the new version which is compatible with Genesis 3 !
Say you want to create a dance animation. You animate the hip sways.
Now comes the hard part where you must, for each frame of the animation,
carefully re-position the legs so the feet don't float above the floor or sink below the floor.
This takes a lot of time and you often end up with shaky trembling feet.
With mcjAutoLimb, you select the foot, and the script makes all the leg work for you -
you get super stable feet!
mcjAutoLimb can also help you for animations where you want a foot or a hand to follow something or grab something
Amother example, you create a null node and position it where you'd like the figure's left wrist to be
select that node, then select that hand, run the script
and presto, the hand moved precisely where you wanted
this works for animations too ! it saved me hours of work over the years.
 The new version (2014/2015) adds "pole vectors" or "poles" for short.
There's an infinity of ways to position a leg so that a foot reaches it's target.
The poles help mcjAutoLimb decide how much "twist" to apply to a leg's thigh joint or an arm's shoulder joint.
In the case of arms, mcjAutoLimb will "point" the elbows according to the pole orientation.
Specifically it's the Y-Axis of the pole node that guides mcjAutoLimb.
If the pole node was a cylinder, the Y-Axis is simply the line going from the base of the cylinder to the top.
In the case of legs mcjAutoLimb will "point" the knees according to the pole vector's orientation.
If you don't specify a pole, the script will create one based on the current knee/elbow aim.

 Installation
The zip package is found at the bottom of this page
unzip it in your daz content folder, typically
C:\Program Files\DAZ\Studio\content\ or C:\Program Files (x86)\DAZ\Studio\content\ or C:\Users\USERNAME\Documents\DAZ 3D\Studio\My Library
once installed, it will appear in your content library, under
Studio / Scripts / mcasual
or
My Library / Scripts / mcasual
Starting with Windows 7 if you right click on the downloaded zip file and select the [Extract All ....] pop-up menu item you simply browse up to your Daz Studio Content Folder
and the files will fall in the proper folder
 USE - Single node This mode is used to keep a foot or an arm where it is, even if the rest of the body is moving
Select a hand or any node parented to a hand
this can be a finger or a sword, as long as it's parented to a hand
or select a foot or any node parented to it
this could be a toe or this cold be a null node positioned at the bottom of the shoe sole
run the script
Specify the range of frames to process and press the "do it" button
the selected foot or hand or finger .... should now stay put!
note how the script created a target node for you
it also created a pole vector ( a null node ) and parented it to the shoulder or thigh
or if a pole node was previously created for this figure and this leg/arm, then it will be found and re-used
you can optionally make the script delete them on exit
 USE - Two nodes : a target and a Targeter You have a "target" node and you want the left hand to follow the movements of this node
select the target node
press the CTRL key, and select the left hand ( which we will call the targeter )
node that the selection order is very important
if you select the hand, followed by the target ... it wont work
so, target first, hand second
 launch the script
Specify the range of frames to process and press the "do it" button
if the target stays withing hand reach, everything should be fine
here again, the script took care of creating and parenting the Pole vector
you can have that node deleted upon exit
or if a pole node was previously created for this figure and this leg/arm, then it will be found and re-used
 Tips for problematic cases Tip 1
The default limits for foreArm joints is sometimes -5 degrees to 135 degrees
this can cause mcjAutoLimb to hesitate between applying a "Bend" of 5 or -5 degrees
mcjAutoLimb is trying to make the arm a certain length and those two angles satisfy the condition
so you may want to go in the parameters tab of the foreArm and change the range of Bend to 5 to 135 degrees
Tip 2
sometimes setting "limits off" on the thighs/shins or the shoulder/foreArm is needed
Tip 3
make sure your target is reachable for the duration of the animation
Tip 4
Read the manual ( web page ) of the old version of mcjAutoLimb
