# Sandbox.LoadingScreen.StepFraction

```csharp
static System.Nullable<double> StepFraction { get; set; }
```

How far through the step in [Sandbox.LoadingScreen.Title](/api/Sandbox.LoadingScreen/Title) it is, 0 to 1, for a bar while nothing's downloading - like
updating a package's shaders. Null when the step can't say. Cleared when the loading screen is hidden.

Declared in [Sandbox.LoadingScreen](/api/Sandbox.LoadingScreen).
Assembly: `Sandbox.Engine`.
