I'm working on a script to split a joint chain into a blended pair, for use in Fk IK system.
I'm trying to loop through all selected joints, and for each iteration, create a pairBlend node and connect it to the related joints.
Code is:
proc EdSplitJointChain(string $splitJoints[])
{
group -n blendChains_grp $splitJoints[0];
rename $splitJoints[0] "result_root_jnt";
group -n result_grp result_root_jnt;
string $resultChain[] = `listRelatives -ad result_grp`;
duplicate -rc result_grp;
searchReplaceNames "result" "a" "hierarchy";
string $aChain[] = `listRelatives -ad "a_grp*"`;
duplicate -rc -n b_grp result_grp;
select b_grp;
searchReplaceNames "result" "b" "hierarchy";
string $bChain[] = `listRelatives -ad "b_grp*"`;
int $size = size($resultChain);
int $i = 0;
string $chainBlend[];
for($i; $i<$size; ++$i)
{
$chainBlend[$i] = `shadingNode -asUtility pairBlend -n ("chainPairBlend"+$i) `;
connectAttr -f ($aChain[$i]).rotate ($chainBlend[$i]).inRotate1;
connectAttr -f ($bChain[$i]).rotate ($chainBlend[$i]).inRotate2;
connectAttr -f ($chainBlend[$i]).outRotate ($resultChain[$i]).rotate;
}
}
where $splitJoints[] is the original chain to be split.
I have problems in the loop section. No matter what I do, I get an error with the name of the shading node: "Invalid object or value: chainPairBlend0"
I've tried changing the order, using a blendColors instead, and still I get the error. I'm mirroring the exact syntax that gets shown in the script history when I do it by hand, I'm just substituting the names with the positions in the $chainBlend[] array.
I know the script is very messy - I'm not good at coding, so any advice is appreciated.
Thanks very much for your help.
