I'm making my own ore, and I want it's autoplace Noise Expression to be the same as stone. Does anyone know what it is or how to figure out? Thanks!

You'd have to reverse engineer it from the `autoplace` field in the resource prototype definition. Its quite nested with a lot of lua functions and the expression itself consists of many noise functions.

You don't need to reverse engineer anything, you can just look at the generated string, which will be in the prototype in data.raw.
