The WithMultiSample4X method is a member of the TextureArrayBuilder class in the Sandbox namespace. This method configures the texture array to use 4x multisampling, which is a technique used to improve the quality of rendered images by reducing aliasing. Multisampling achieves this by sampling a pixel multiple times at different sample points and averaging the results.
To use the WithMultiSample4X method, you must first create an instance of the TextureArrayBuilder class. Then, call the WithMultiSample4X method on this instance to enable 4x multisampling for the texture array being built. This method returns the same TextureArrayBuilder instance, allowing for method chaining.
// Example of using WithMultiSample4X
TextureArrayBuilder builder = new TextureArrayBuilder();
builder.WithSize(1024, 1024)
.WithFormat(ImageFormat.RGBA8)
.WithMultiSample4X();
Texture texture = builder.Finish();
// The texture is now created with 4x multisampling enabled.
