Fix: Unity Mesh BatchRendererGroup PSO Precompile Misses Custom Shaders

DOTS-style instanced rendering; first frame stutters from PSO compile.

Manually precompile

Loop BRG materials; precompile each variant. One-time cost.

Or pre-render frame

Render BRG once at boot offscreen. PSO compile during loading screen.

Audit per shader

BRG shader list; verify each is in precompile flow.

“BRG bypasses standard PSO precompile. Manual coverage required.”

If you ship BRG, the precompile audit is mandatory. First-frame hitches are visible.
