Exporting attribute curve from FaceFx?


we were wondering if it was possible to have attribute curve(float) for each poses in FaceFx. And export those curve to be used as material curve in Unreal.

With just want to use those float curve to make our wrinkle work.


Yes, attribute support is coming in FaceFX 2017 (due out in a couple weeks). Just create a node attribute in your source FBX file, and create a new FxAttribute node in FaceFX with the same name, and we'll write the curve data there in all output FBX files.

The pipeline into UE4 is still in flux, so I can't speak to that, but you will be able to get the curves into an FBX file from FaceFX.

if you are using the facefx ue4 plugin, material parameters aren't implemented yet. But if you can get access to the morph curves inside of UE4, you might be able to rig up fake morph targets to drive the parameters you want...but that's the best I can think of at the moment.
