Or might need to test for direction of rotation and add or subtract (the full rotation counter) 2pi. Like slerp() from quats.

Wow... thanks Dan, exactly what i wanted. if it also could automaticly fix the big jumps in the graph when the value crosses 360degrees, then you should make an deal with adobe to supply this as a standard script with AE ;-) - Robert 2013/4/24 Dan Ebberts <debberts@comcast.net> Try this: { var myComp = app.project.activeItem; if ((myComp != null) && (myComp instanceof CompItem) && (myComp.selectedLayers.length != 0)){ app.beginUndoGroup("Convert 3D Orientation to Rotation"); var myLayer; var myVal; var t; for (var i = 0; i < myComp.selectedLayers.length; i++){ myLayer = app.project.activeItem.selectedLayers[i]; myOrientation = myLayer.property("Orientation"); if (myOrientation.numKeys > 0){ for (var j = 1; j <= myLayer.property("Orientation").numKeys; j++){ myVal = myLayer.property("Orientation").keyValue(j); t = myLayer.property("Orientation").keyTime(j); myLayer.property("xRotation").setValueAtTime(t,myVal[0]); myLayer.property("yRotation").setValueAtTime(t,myVal[1]); myLayer.property("zRotation").setValueAtTime(t,myVal[2]); myLayer.property("orientation").setValueAtKey(j,[0,0,0]); } }else{ myVal = myLayer.property("Orientation").value; myLayer.property("xRotation").setValue(myVal[0]); myLayer.property("yRotation").setValue(myVal[1]); myLayer.property("zRotation").setValue(myVal[2]); myLayer.property("orientation").setValue([0,0,0]); } } app.endUndoGroup(); }else{ alert("Please select at least one layer..."); } } Dan From:

No... i just want to manually adjust some of the keyframes of the rotation, eg. smoothing some areas, but that is really hard to do with the orientation keyframes when it jumps from 359.9 degrees
to 0, making huuuge visual jumps in the graph editor. - Robert 2013/4/24 scott.aelist <scott.aelist@gmail.com> > Doing any adjustments on a keyframed orientation is really counterintuitive. Sounds like you want to use an expression rather than a script then? |
