## Syntax

```lua
bool engineSetMaterialAlphaClip(material material, float|false|nil clip)
```

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `material` | `material` | The material. |
| `clip` | `float\|false\|nil` | The alpha threshold, from 0 to 1. `false` turns cutting out off. `nil` follows the base again. |

## Returns

`true` when it was set.

## Example

```lua
local leaves = engineCreateMaterial()
engineSetMaterialAlphaClip(leaves, 0.4)
engineSetWorldMaterial("*leaves*", leaves)
```

### Note

A number outside 0..1 is an error, and so is `true`.
