How can I make parts of a structure look different enough from each other

I’ve made a wooden structure in which you can see a trainstation. https://codepen.io/michielschukking/pen/OPRdEWV?editors=0010

I like architecture with rhythms. But to see these rhythmic figures line up it is handy if objects look a little different from each other. Different parts I already colored to stand off of each other.

Maybe by:

  • Shadows on the ground. How do I do this? groundMesh.receiveShadow = true; does nothing, and this would help greatly with estimating height.
  • Distance fog. This could help make the beams stand loose of one another.
  • Textures. Some kind of simple pattern that can make the beams look loose of one another.
  • What would be really great is a line around each object, comic-book-style. That could be really helpful interpreting the structure.
  • Making them see-through transparent. This could really help with parts that should ‘click’ into each other.

Hopefully more complex structures are coming. If you see something (easy) that can help with interpreting this geometry please help. Thank you!
