CapsuleHand_L and a CapsuleHand_R to your scene and make them children of the Leap Hand Controller

Setup LeapMotion VR Scene• From LeapMotion>Prefabs>HandModelsPhysical drag a

RigidRoundHand_L and a RigidRoundHand_R to your scene and make them children of the Leap Hand Controller

Setup LeapMotion VR Scene• Locate the HandPool component attached to the LeapHandController• Set Model Collection value to 2 – drag capsuleHands(L/R) and

RigidRoundHands(L/R) from Hierarchy to empty slots• Click Is Enabled and Can Duplicate on both Elements

when you bring them upto the leap motion camera

using the inbuilt Unity Physics Engine

Optimising for Framerates & Quality• Select Project Settings – Quality• Select Simple and change Anti

Aliasing to 4x Multi Sampling• Anti Aliasing is very important in

VR and where possible should be enabled

• Increase Default Render Scale from 1.0 to 1.5 which increases object sharpness – see next slide

• Avoid Dynamic Lighting where possible – best to bake lights

How to Increase Render Scale• Create new C# file called RenderScale• Add the following code and attach script to the LeapSpace Object in your

Hierarchy• Code is from Unity Getting Started Tutorial - http://tinyurl.com/j2elrjt
