- Technical Considerations (Critical):
-
Components:
- Base unit for:
- Rendering
- Visibility calculations
- Collisions
- Must be square & same size
- Each stored in single texture
- “Power of two texture size” required
- Duplicates vertices along shared edges
- Base unit for:
-
Sections:
- Division options:
- One section (1x1)
- Four sections (2x2)
- Max size: 256x256 vertices
- Used for LOD calculations
- Division options:
-
Performance Balance:
- Smaller landscapes:
- Faster LOD transitions
- Better terrain occlusion
- “Requires more components”
- Each component:
- Has CPU processing cost
- Each section = one draw call
- “Epic’s max recommendation: 1,024 components”
- Smaller landscapes:
