The WithDepthFormat method is a part of the Texture2DBuilder class in the Sandbox API. This method configures the texture to use a depth format, which is typically used for depth buffering in rendering pipelines. Depth formats are essential for operations like depth testing, which helps in determining the visibility of objects in 3D space.

To use the WithDepthFormat method, you need to have an instance of Texture2DBuilder. This method is chainable, meaning you can call it in a sequence of method calls to configure various aspects of the texture before finalizing it with the Finish method.

Example usage:

var textureBuilder = new Texture2DBuilder();
textureBuilder.WithDepthFormat();
var texture = textureBuilder.Finish();

This example demonstrates how to create a texture with a depth format using the builder pattern.
