Micro Variation

• Addressing Tiling Issues:

• Two main solutions:
  • Micro variation (color tinting)
  • Macro variation (large scale)

• Micro Variation Implementation:

• Base Setup:

  • Multiply base color with tint parameter
  • Default tint = white

• Variation Process:

  1. Duplicate base color & tint
  2. Add seamless noise texture
     • Use T_Macro_Variation or Perlin
     • “Very small UV scale (0.01)”
  3. Linear Interpolate (Lerp):
     • A = Base tinted texture
     • B = Variation tinted texture
     • Alpha = Noise (red channel)

• Key Components:

• Parameters needed:
  • Base tint
  • Variation tint
  • Micro variation scale
• “Uses only red channel of noise”
• “Small scale crucial for subtle effect”

• Results:

• “Reduces obvious tiling at close range”
• “Still needs macro variation for distance views”
• Customizable via material instance
