The "Convert" menu allows you to specify that the parameter should be controlled automatically in various ways. Ok, but once the parameter is converted to the other(s) one(s), how can it be automatically controlled? Maybe the parameter is now controlled by waypoints and keyframes as the normal parameters?. I'm interested into this feature because I have found that some layers (Eg. Curve Gradient) donesn't work properly in the version I have of synfigstudio (Vertices are "Unknown type". I hope using "convert" can arrange it and use some types of layers that seems that the default values are incorrectly set. Bye, Genete.
