Distance Blending

• Distance Blending Purpose:

• Solves far-distance tiling issues
• “Keep close detail, fix distant views”
• Uses two UV sets:
  • Near (close-up view)
  • Far (distant view)

• Implementation Setup:

• Duplicate UV Sets:

  • Create near/far parameters per layer
  • Need two texture sets

• Distance Blend Node:

  • Key Parameters:
    • Blend Range (default: 100)
    • Blend Offset (default: -1000)
    • “Larger values needed for landscapes”
  • Controls transition between sets

• Texture Blending Process:

• Linear Interpolate (Lerp):

  • Alpha = Distance blend
  • Blend between:
    • Normal maps
    • Base colors

• ORD Maps Special Handling:

  • Break into components
  • Blend individual channels:
    • R = Ambient Occlusion
    • G = Roughness
    • B = Displacement

• Organization Tips:

• “Use named reroute for distance blend”
• “Separate UV tile comments”
• “Color code layers (R,G,B)”
• “Save often - crashes can happen”

Part 2

• Distance Blending Implementation:

• Process Per Layer:
  • Duplicate UV networks
  • Apply tinting variation to both sets
  • Linear interpolate between sets using:
    • Normal maps
    • Base colors
    • ORD maps (broken into RGB)

• Key Parameters:

• Blend Controls:
  • Offset: “Distance where blend starts”
  • Range: “Distance over which blend occurs”
  • Default values:
    • Blend Range: 1000
    • Blend Offset: -1000
    • “Must adjust per landscape”

• Organization Structure:

• Parameter Groups:
  1. UV Tile (0,0 priority)
  2. Macro Variation
     • Texture & contrast
     • Scale controls
  3. Distance Blending
  4. Layer Tinting
  5. Layer Textures

• Fine-Tuning Tips:

• Test in play mode
• Check both:
  • Close-up view
  • Bird’s eye view
• “Adjust values until tiling invisible”
• “Use F8 for real-time adjustments”

• Final Result:

• “Significant improvement over basic tiling”
• Combines:
  • Macro variation
  • Tinting variation
  • Distance blending
