Help Wanted: Im harding coding the surface conditions for different ores, does anyone know a way to dynamically find what surface each resource can spawn on and then get its merged surface condition? I want this to be able to work for any new planets and it should be able to find any new resource patch, but not necessarily its surface conditions.

For example coal can be found on nauvis and vulcanus and so its surface conditions need to include those two but exclude everywhere else.

I don't have the DLC, but can't you use resource_prototype.suface_conditions?

Though this doesn't account for the spawning conditions of the resource: frequency can be set to zero by the mapgen parameters I think (maybe only possible indirectly).
