I want to use interaction engine to grab and move objects in Unity and I found the tutorial on youtube: https://www.youtube.com/watch?v=MM7oyMv2uL8&t=76s . But I just can't find BrushHand_L and BrushHamd_R in interaction engine prefab. I found Interction Hand(Right) and Interaction Hand (Left) but i cant drag them to Leap Hand Controller Physics Hand what is solutions ? i use unity 5.6.1 and Leap_Motion_Interaction_Engine_1.0.1. Thank you so much.
