## **Scene Preparation**

> Make sure the scene has a **correct physical scale**.

> 
> Set up the **tracked camera**.
> 
> 1. Add a new **Physical camera**. The location of the camera in the scene doesn't matter.
> 2. Set the **Focal length** and **Film gate** to match the actual camera used on set.
> 3. Set a reasonable **Focus distance**, for example, **2 meters**.
> 4. Adjust the **exposure **of the camera according to the scene.
>

> > Macro (refined-step)

> Set up the **projection**, depending on the desired workflow:
> 
> 1. Add **stage position nodes **if you use a **[Stage Geometry scene](https://docs-chaos.atlassian.net/wiki/spaces/ARENA/pages/125112236)** in the [configuration](https://docs-chaos.atlassian.net/wiki/spaces/ARENA/pages/125143783).
> 2. Alternatively, directly **import **the stage geometry into the scene and position it as desired.
> 
> 
> > Macro (refined-step)
> 
> Set the **render resolution** to match the camera's aspect ratio. A high enough resolution is also helpful for the operator instances, as Arena clamps the render resolution to the camera resolution in the scene by default.
> 
> 
> > Macro (refined-step)
> 
> **Repath **all assets to a shared network drive if needed.
> 
> 
> > Macro (refined-step)
> 
> **Export **a **.vrscene** file.
> 
> 1. Ensure the **primary render camera** is the tracked camera in the exported scene.
> 2. Make sure to enable **animation export** if there are animations in the scene.
> 3. Use the **Archive **option in the **.vrscene** export settings if desired. It packs the scene and all assets and makes it portable. Useful if local assets are not stored in a shared location. In this case, re-pathing the assets is unnecessary; all paths are converted to relative.
