Introduction to Lowpoly Mastery
Second Life calculates Land Impact (LI) based on the highest of three costs: Download, Physics, and Server. To maximise visual fidelity while keeping your prim count minimal, follow these core principles:
Never upload your high-polygon visual mesh as the physics model. Always model a simplified hull or use bounding box primitives. Generate custom Low and Lowest LODs rather than relying on automatic decimation. This prevents avatar pop-in and maintains visual integrity across distance. Leverage modern 2K PBR materials (Roughness, Metallic, Normal) to add tactile depth without geometry bloat.
