Maya Learning Channel | Appendix A: Part 1 – Matching the FK arm to the IK arm
In Appendix 2 @9:26 both of my FK to IK arms switching is not working but everything else is. Below are examples of the outcome.
Judging from these worldspace queries, I my controls do not appear to be frozen yet they are and must have been moved after being frozen to give it these readings.
xform -query -worldSpace -rotation leftArm_CTRL;
// Result: 0 0 0 //
xform -query -worldSpace -translation leftArm_CTRL;
// Result: 0.695788 4.453783 0 //
Solution:
As stated by Maya Learning Channel in an answer to Gamerwhogames I applied this code:
For the leftArm_CTRL find :
$t_hand = `xform -query -worldSpace -translation rightArm_IK_snap_GRP`;
and Replace with:
$t_hand = `xform -query -worldSpace -translation leftArm_CTRL`;
$t_rp = `xform -query -worldSpace -rotatePivot leftArm_IK_snap_GRP`;
$t_rp2 = `xform -query -worldSpace -rotatePivot leftArm_CTRL`;
$t_hand[0] += $t_rp[0]-$t_rp2[0];
$t_hand[1] += $t_rp[1]-$t_rp2[1];
$t_hand[2] += $t_rp[2]-$t_rp2[2];For the rightArm_CTRL find :
$t_hand = `xform -query -worldSpace -translation rightArm_IK_snap_GRP`;
and Replace with:
$t_hand = `xform -query -worldSpace -translation rightArm_CTRL`;
$t_rp = `xform -query -worldSpace -rotatePivot rightArm_IK_snap_GRP`;
$t_rp2 = `xform -query -worldSpace -rotatePivot rightArm_CTRL`;
$t_hand[0] += $t_rp[0]-$t_rp2[0];
$t_hand[1] += $t_rp[1]-$t_rp2[1];
$t_hand[2] += $t_rp[2]-$t_rp2[2];
Example before:
Above: The left arm posed with the FK controls.
Example after:
Above: The left arm after IK switch via MEL script UI.
