On-Demand WebSearch Strategy
For plugins NOT listed above, use the following approach when users ask:
- WebSearch for latest documentation:
"Unreal Engine 5.7 [plugin name]" - Verify if plugin is:
- Post-cutoff (beyond May 2025 training data)
- Experimental vs Production-Ready
- Still supported in UE 5.7
- Optionally cache findings in
plugins/[plugin-name].mdfor future reference
Quick Decision Guide
I need abilities/skills/buffs → Gameplay Ability System (GAS) I need cross-platform UI (console + PC) → CommonUI I need dynamic cameras → Gameplay Camera System I need procedural worlds → PCG I need large crowds (1000s of AI) → Mass Entity I need destructible environments → Chaos Destruction I need vehicles → Chaos Vehicles I need water/oceans → Water Plugin I need VR/AR → OpenXR
