# FAQ & Best Practices

#### ❓ Frequently Asked Questions

**Does this tool modify the engine’s global scalability settings?**\
No. It only overrides CVars **locally while the player is inside a volume**. Once they leave, the values revert.

***

**What if the player has a different scalability level set?**\
The volume respects the player's current **scalability setting** and applies the correct override value from the array.\
This allows the tool to **adapt dynamically**, rather than force a single value.

***

**Can I use this in multiplayer?**\
Yes, but it’s **not replicated**. Each client/player will apply overrides **individually** on their own device.

***

**Does it support all scalability categories?**\
Yes — it supports:

* Global Illumination
* Reflections
* Shadows
* Foliage
* Post Processing\
  …and more. All values are mapped using Unreal’s standard scalability tiers (Low to Cinematic).

***

**Can I override multiple settings in the same volume?**\
Absolutely. Just add multiple triggers to the same volume.

***

**What’s the difference between this and Profiler or Analyzer?**

* **Performance Volumes** = Applies real-time CVar overrides per area
* **Profiler** = Real-time rendering stats and overlays
* **Analyzer** = Offline scanner for asset-level issues\
  ✅ All are designed to work together.

#### ✅ Best Practices

🧱 **Use volumes to contain high-cost rendering**\
Apply quality overrides **only where needed** (e.g. close-up Lumen, cinematic zones).

***

🏡 **Disable outdoor features indoors**\
Use `r.VolumetricCloud = 0` or similar to improve performance in enclosed environments.

***

🎮 **Use tags for advanced character detection**\
Set `Trigger Actor Tag` if you need to target specific pawns, AI, or VR rigs.

***

🔁 **Test at different scalability levels**\
Make sure each index in the arrays behaves properly across Low to Cinematic.
