I was using this tutorial, and I found something that wasn’t working, and wanted to let you know what I did to make it work.

At this point

“thisComp.layer(“Butterfly Controller”).effect(“Wing Rotation”)(“Angle”);

Then Apply a similar expression to the Y Rotation of the left wing (notice the *-1):

thisComp.layer(“Butterfly Controller”).effect(“Wing Rotation”)(“Angle”)*-1;”

I had to change “Angle” to “Slider” because it’s a slider controller and not an angle controller.
