Building & Modeling
- Align / Mirror — symmetry and precision layout
- Arch / Curve / Path tools — roads, railings, pipes
- Gap Fill / Vertex tools — stitch seams cleanly
- Material/Color Swapper — fast theme iteration
- Terrain Editor — sculpt/paint with locked metrics
Workflow
- Package/Asset Managers — reuse modules across places
- Instance Find/Replace — mass refactor names/props
- Profiler overlay — measure spikes while iterating
AI Helpers
- Code copilots — draft Lua, refactor, add comments
- Image/Texture upscalers — upscale icons & UI safely
- Prompt-based skybox/thumbnail generators (export 1024–2048)
- Sound design AI — short SFX variations with loudness normalized
Testing & QA
- Device emulation — low/mid/high presets, FPS capped
- Streaming testers — teleport, stress regions, report unloads
- Memory/Inst-count inspectors — prune worst offenders
Tip: keep a separate QA place with microbench maps for props, UI, particles, and pathfinding to profile changes quickly.
