Grass System Prototyping

Grass Prototyping

Experimental grass implementations exploring different approaches:

• MultiMesh grass: Initial attempt using MultiMeshInstance3D
• 4-zone LOD system: Distance-based density zones (later replaced with smooth blend)
• Continuous LOD blend: Smooth density falloff instead of discrete zones
• Emergence animations: Grass growing up from ground (removed for simplicity)
• 500m range: Extended grass coverage with sharp density falloff

Iteration Notes

These experiments informed the final GPU particle system:

• MultiMesh had update performance issues → switched to GPU particles
• Discrete LOD zones looked jarring → smooth blend better
• Emergence animations added complexity without visual payoff → removed
