## Syntax

```lua
bool engineSetReflections(int probeSize, float marchScale [, int marchSteps = 24])
```

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `probeSize` | `int` | Pixels per side of the probe that captures the surroundings: 0 reflects only the sky; otherwise a power of two from 32 to 1024. The default on PC is 256. |
| `marchScale` | `float` | Fraction of the resolution screen-space reflections are computed at: 0 turns them off; otherwise from 0.25 to 1. The default is 0.5. |
| `marchSteps` | `int` | Steps each screen-space reflection ray takes, from 4 to 64. *(default: `24`)* |

## Returns

`true` if the setting was applied, `false` if the renderer is not running.

The setting applies to the whole client and stays after the resource stops.

## Example

```lua
engineSetReflections(128, 0)
```

### Note

Any value outside the limits raises an error.
