History
June 28 2014 8:60 PM release
July 20 2014 10:21 PM new version improves finding an re-using previous "pole" nodes
Introduction
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 it also can help you for animations where you want a foot or a hand to follow something or grab something
For 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 "old version" is and will remain here : https://sites.google.com/site/mcasualsdazscripts/mcjautolimb
The new version adds "poles of attraction" or "poles" for short
Since there's an infinity of ways to position a leg so that it reaches its 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 toward the pole you specify
in the case of legs it will "point" the knees toward the pole you specify
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\
once installed, it will appear in your content library, under Studio / Scripts / mcasual
or
C:\Users\Public\Documents\My DAZ 3D Library\
once installed, it will appear in your content library, under My DAZ 3D Library / Scripts / mcasual
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 node far in front of the knee or far behind the elbow
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 node to the figure's collar bone
if the targeter was a foot, the Pole node is parented to that leg's buttock
and 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
the script will not attempt to delete that type of pole node
USE - Three nodes : a Target, a Targeter and a Pole
You have a "target" node and you want the left hand to follow the movements of this node
and you created and animated a Pole node to control the elbow's behaviuour
select the target node
press the CTRL key, and select the left hand ( the targeter )
still holding the CTRL key, select your pole node
( the selection order is very important )
Specify the range of frames to process and press the "do it" butto..
Done !
This image shows how mcjAutoLimb rotates the plane passing through the shoulder, fore-Arm and thumb joints, so that it passes through the Pole ( green ball )
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
