Getting Parameters from subject in LiveLink
Looks like subjects can pass custom parameters via LiveLink and those can be accessed in MotionController's Motion Source: https://docs.unrealengine.com/en-us/Engine/Animation/Live-Link-Plugin
I've made custom blueprint derived from MotionController class, have set the MotionSource to my subject(Maya Live Link), overrided event on MotionControllerUpdate with added GetParameterValue node.
MotionController component is hooked up to MayaLiveLink, since I can interact with it's transforms from Maya,but I can't get any parameters from GetParameterValue node (ValueFound bool is false). I've tried to use "Translation X", "Intensity" (when using Light subobject), I've tried to create custom attributes with simple names like "a", and so on, but nothing does seem to be picked up by GetParameterValue node. Should I setup subject's parameters in Maya in some special way? Or am I tying access wrong parameter names?
I did some research and I've come to conclusion is that the feature is not finished yet.
