"Experimental support for facial animation"?

Yes, and code. Create a component or actor that implements the ICurveSourceInterface interface. There are three functions to implement, although only two are important right now: GetBindingName() and GetCurves(). The binding name is used by the curve source anim node to bind at runtime to name returned from GetBindingName(). The node can bind to components of the current actor, the current actor itself, or components or actors stored as member variables of that actor. GetCurves() returns an array of name/value pairs that specify the value each named curve will receive in the anim graph. Note that curves can drive pose weights, blendshapes, material parameters etc.

I don’t really know how to set this up. I’ve got a character with an AudioCurveSource component set up with a random sound wave. The binding name is Default. In the anim BP I’ve got a random animation without curves hooked up into a Curve Source node with the source binding named Default. I guess this should complete the binding, but what creates the actual curves? I had the assumption that this was something that turned the amplitude of the audio into curves but looking in the code it looks like it’s supposed to work with .fbx with curves and sound somehow.

Can you use Audio Source in 4.16 or are there parts missing? I’m testing with a morph target called Key 1 but I’m a bit lost on how to continue.
