[AR] Hand tracking with real objects

Want to make my hand interact with virtual object or augment real object there are two problems: hand tracking when the object hide some part of the hand and the object tracking if it’s real.

Appear there are a nice UE4 support for Leap Motion controller but the technology didn’t work well with occlusion, looking at Perception Neuron appear to be a better solution but I’m not sure how well is supported their UE4 plugin.

Anyone can suggest other suitable options.
