Painting

• Basic Landscape Material Setup:

• Create Material Structure:
  • Use Layer Blend system
  • Three basic layers:
    • Index 0: Rock (base)
    • Index 1: Grass
    • Index 2: Snow
  • “All layers use Weight Blend type”

• Essential Components:

• Layer Requirements:
  • Landscape Layer Blend node
  • Albedo textures per layer
  • “Must create Layer Info for each layer”
    • Create via: Weight Blended Layer Normal
    • “Landscape stays black until Layer Info assigned”

• Painting Tools:

• Core Functions:
  • Paint: Basic layer application
  • Smooth: Blend layer weights
  • Flatten: Average weights between layers
• Tool Settings:
  • Default strength: 0.3
  • “Large operations: ~3.0 strength, 4K brush”
  • “Detail work: Lower strength, 2K brush”

• Key Issues:

• “Tiling problems need UV control”
• “Requires landscape coordinate node”
• “Shaders compile per landscape component”
