Editing Enabling Touch Responsiveness

The touch-responsiveness requires that Unity generate a camera-depth texture, which is dependant on the world's lighting. In worlds that do not have the correct lighting, you can add one to your avatar (note that this will automatically make your avatar rating "Poor").

== Adding a Directional Light to your Avatar ==

=== Step 1: Left-click on your avatar, and select "Light -> Directional Light" to add a new light: ===

=== Step 2: Select the newly created light, and change the following 4 settings: ===
'''Step 2a: Make sure the checkmark in the upper-left is enabled.'''[[File:Touch Response - Light settings.png|none|thumb|500x500px|1The Directional Light settings]]

=== Step 3: Confirm that the light is working by enabling "Show Contact Zones". If the lighting is not correct, a checkboard pattern will appear: ===

== Preventing Self-Triggering ==
The touch-response works by using the camera depth-texture to detect nearby objects. Unfortunately, this means the body will self-trigger in crevasses. The "Show Contact Zones" blue areas indicate where this self-triggering is occurring:

This problem can be reduced by adding an "Occlusion Map" that has been baked in Blender to your avatar. The sensitivity level can then be adjusted so that crevasses are excluded (indicated by the red areas):

'''Note: in the future, this feature will be moved to a separate mask, which will be directly editable using the Fur Grooming.'''
