# EnvironmentResource.CreateOptions

A type that controls compression, sampling quality, and cubemap dimensions when creating an environment resource.

## Declaration

```swift
struct CreateOptions
```

## Overview

Overview The options provide control for balancing memory usage, quality, and processing power when creating an environment’s lighting data.

## Topics
