I can make some basic sorts of 2D shapes with Open Simplex or Perlin Noise, but I'm looking for tutorials on how to make various specific 2D things. For example, wood textures, marble textures, etc. I can't seem to find any online tutorials that go beyond very basic concepts. Could you please suggest some tutorials that explain how to do specific things with noise? I am used to coding in Java or Python, but any language is fine.
