# DT project layout
> Folder map under Assets/_MolcaDT for molca-sdk-dt.
Paths are relative to **`Assets/_MolcaDT/`** in **molca-sdk-dt** (or your fork).

Use **Unity’s Project search** (`t:Script RootManager`, etc.) or your IDE to find consumers. Naming is **DT-specific** — do not assume [VR scenario types](/vr/scenario-manager) exist under `_MolcaDT`.
## Troubleshooting
* **Script not found after clone** — Ensure the **molca-sdk-dt** package/folder is under **`Assets/_MolcaDT`** (or your fork’s equivalent); asmdef / platform settings may hide scripts if the folder was moved outside Unity’s asset database.
* **Wrong manager firing** — Many types use **`instance` singletons (**`NetworkManager`\*\*, **`POIManager`**, **`TokenRenewalManager`**); duplicate bootstrap objects cause **`Destroy`** or double requests—keep one **DT root** scene.
* **Namespaces** — Production code mixes **`MolcaDT.*`** with **`Molca.DigitalTwin`** (`**DigitalTwinDynamicModule**`); search both when tracing URLs and auth.
* **Editor-only tooling** — **`Editor/`** scripts apply only in the Unity Editor; CI builds omit them—do not reference editor types from runtime assemblies without guards.
* **Upgrade / merge conflicts** — **`Handler/Panel Handler/`** is deep; prefer adding new panels in a subfolder than editing stock handlers, to ease upstream merges.
