Hi ima trying to write a script that will alter tangents in graph editor. but when i run it, it "breaks" the tangent of the graph. Why is that? its getting on my nerve,r i dont know what else to try. This is the line im using to change the tangent:

keyTangent -e -outWeight 1 -inWeight 1 -l 1 -r -t $t1 -inAngle ($anglefield \* 1) -attribute $a $s;

any clues? why does it break the tangents?
