This repository is really out of date! I'm leaving it intact since I have some videos and tweets referencing it. Any newer shader work will go in a https://github.com/y2kcyborg/obs-shaders

Putting Together the Reflection Effect

• Your avatar needs to trigger the conditions for the bug I'm exploiting, I recommend:

  • VRM avatar in VSeeFace
  • Glasses material using 'Standard' shader in 'Transparent' rendering mode
    • Colour: black with alpha between 0.5 and 0.95

• Scene 'Avatar Lighting'

  • 'Avatar' - avatar source
  • Source for other accessories that should receive lighting
  • 'Game Mirrored Blurred' - source mirror of game source (hidden)
    • Blur: Dual Filtering, Area, Size 6.0
    • 3D Transform: Orthographic, Scale X -100%
  • (On Scene) Dynamic Mask
    • Input: 'Game Mirrored Blurred'
    • Red Channel: Base 0.2, Red Input 1.0
    • Green Channel: Base 0.2, Green Input 1.0
    • Blue Channel: Base 0.2, Blue Input 1.0

• Scene 'Avatar Reflection':

  • 'Reflection Mask' - source mirror of avatar source (hidden)
    • Shader: 01-alpha-to-mask-and-erode.effect
      • Thresholds can be used to help get rid of stray pixels, make sure you keep glasses surface within threshold
    • Blur: Dual Filtering, Area, Size 1.0
  • 'Blend Group' - Group
    • 'Reflection' - source mirror of game source (hidden)
      • Shader: 02-sphere-distort.effect
        • Default values should be a reasonable starting point
        • Try to make a sphere behind your head that follows glasses surface as you move your head around
        • Play with the "Tint" option at the bottom
      • Blue: Box Linear, Area, Size 3.0
      • Dynamic Mask
        • Input: 'Reflection Mask'
        • Alpha Channel: Base 0.0, Red Input 2.5 (this will bias/grow the mask after the blur on it)
    • 'Avatar Lighting' - Nested scene from last step
      • Edit Transform: Y Position = 1080 (or whatever your canvas height is)
    • (On Group) Shader: 03-blend-group-special.effect
      • Special Sauce: Enabled
      • Upper Source Gain: Control amount of reflection
      • Lower Source Gain: Control amount of transmission

Now drop scene 'Avatar Reflection' in where you want your avatar!
