# Sandbox.SpriteRenderer.RefractionStrength

```csharp
float RefractionStrength { get; set; }
```

Maximum refraction offset in render pixels before the normal is applied. Alpha, depth feathering
and camera fading affect artwork opacity only, never the refraction. Zero leaves the background undistorted.

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