script not finding the model in the scene

Hey Fellow Daz entousiast !

i'm following the tutorial here (https://www.deviantart.com/3dstrobist/journal/Transfering-Mixamo-Animations-to-Daz-Genesis-8-1-906594358) to import mixamo animation into Daz and apply it to a G8 model, but when I try to execute the script from this tutorial to fix the messed up rotation, i get this error:

TypeError: Result of expression 't2' [null] is not an object.
Stack Trace: ()@F:/daz2unity/g8mixamo fix.dsa:11
Error executing script on line: 11
Script executed in 0 secs 7 msecs.

it seems that the script is not able to grab t2 (the genesis 2 model)

here is the script if you dont need to go through the tutorial:

function transferY(a,b){

var t8,t2;

t8=Scene.findNodeByLabel(a);

t2=Scene.findNodeByLabel(b);

var valr=t2.getYRotControl().getValue ();

t8.getYRotControl ().setValue (valr); 

}

function transferX(a,b){

var t8,t2;

t8=Scene.findNodeByLabel(a);

t2=Scene.findNodeByLabel(b);

var valr=t2.getXRotControl().getValue ();

print (valr);

t8.getXRotControl ().setValue (valr); 

}

var nframes=Scene.getAnimRange().getDuration ().valueOf()/Scene.getTimeStep().valueOf();

for( var fr = 0; fr <= nframes; fr+=1 ){

Scene.setFrame( fr );

transferY("Left Thigh Twist","lThigh");

transferY("Right Thigh Twist","rThigh");

transferX("Right Shoulder Twist","rShldr");

transferX("Left Shoulder Twist","lShldr");

transferX("Left Forearm Twist","lForeArm");

transferX("Right Forearm Twist","rForeArm");

} 

thank you in advance for your help!

You need to insert soem error checking, for example make sure that t2.inherits( "DzSkeleton" ) is true before trying to access its members - in this case I think the label you are using is not matching the figure and so t2 is null, which of course fails to find any members. Error checking and, in develppement stage at least, printing notes to the output are always a good idea.

私も同じ問題を抱えていました。
私は解決策を見つけました。
スクリプトの問題ではありません。
3DStorobist のコードは一文字たりとも間違っていません。
まず、前提として FBX to Mixamo を作成しておく必要があります。
次に、アニメーションを Genesis2 から Genesis8 に転送できます。
ここからが本題です。
みなさん、共同編集に切り替えてスクリプトを適用していますか？
これは私たち全員が陥る罠です。
ほとんどの人はそれをユニバーサルにしてスクリプト化します。
共同エディターでスクリプトを実行してみましょう。

i had the same problem. i found a solution. It's not a script issue. 3DStorobist's code is not a single letter wrong. First, you need to create FBX to Mixamo as a prerequisite. Then you can transfer the animation from Genesis2 to Genesis8. Here is the main issue. Have you all switched to co-authoring and applied scripts? This is a trap we all fall into. Most people make it universal and script it. Let's run the script in co-editor.
