306D: The Instanced Fleet
"Drawing 1,000 asteroids means 1,000 "Draw Calls." The CPU has to say "Draw this" 1,000 times. A Navigator uses GPU Instancing to say "Draw this asteroid 1,000 times" in a single breath."
The Concept: GPU Instancing
Instancing allows the GPU to draw the same mesh many times with slightly different properties (Position, Color).
* **Material Option:** "Enable GPU Instancing" checkbox.
* **Property Block:** Using `MaterialPropertyBlock` to set data per-instance.

The AI Trap: "The Unique Material"
You ask the AI: "Give every asteroid a random color."
// AI-Generated Code: Batch Breaker
void Start() {
// Audit Fail: Accessing .material creates a NEW material in memory.
// You now have 1,000 materials and 1,000 draw calls.
renderer.material.color = Random.ColorHSV();
}
This is "State Thrashing." The GPU has to stop and switch materials for every single rock.
Elite Telemetry
Research shows "Elite" teams achieve 15% faster lead times by keeping AI on a "very tight leash."
- Small Batches Solving one problem at a time prevents logic drift.
- Modular Design Localizing the "blast radius" of AI changes.
- Tight Loops Rapid iteration with constant code review.
The Navigator's Correction
Corrective Protocol
// Corrected: 1 Draw Call
MaterialPropertyBlock block = new MaterialPropertyBlock();
block.SetColor("_Color", Random.ColorHSV());
renderer.SetPropertyBlock(block);
