  NoiseTexture can also generate normal map textures.
  The class uses [Thread]s to generate the texture data internally, so [method Texture2D.get_image] may return [code]null[/code] if the generation process has not completed yet. In that case, you need to wait for the texture to be generated before accessing the image and the generated byte data:
  [codeblock]
- var texture = preload("res://noise.tres")
- yield(texture, "changed")
+ var texture = NoiseTexture.new()
+ texture.noise = OpenSimplexNoise.new()
+ await texture.changed
  var image = texture.get_image()
  var data = image.get_data()
  [/codeblock]
