Directing materials with a mood board instead of a prompt
Words are a poor way to describe travertine. A reference board says it at once - and the render reads it as material, not as a picture to copy.

A prompt that asks for warm stone and bronze will get stone and bronze, but rarely yours. A reference image tagged as material tells the engine what the surfaces should be made of, while the geometry still comes from your source.

One board, many views
Because the board is a node on the canvas, the same palette feeds every view of the project. Change a sample once and every render downstream can be run again with it.
