MapGenSettings width height not work

[Xeon257]

Hello. I am developing a planetary mod for Factorio. I would like to restrict the size of a planet’s surface, but even if I set the width and height values in MapGenSettings, the map size does not seem to be limited. Also, the seed value appears to be ignored. Is it impossible to configure these settings at the prototype stage?

==== prototype.planet.planet.lua ====
...
subgroup = "planets",
map_gen_settings = linox_map_gen.linox_crust(),
pollutant_type = nil,

==== prototype.planet.map_gen.lua ====
...
seed = 100, -- not work
width = 32 * 4, -- not work
height = 32 * 4, -- not work

no_enemies_mode = true, -- work
peaceful_mode = true, -- work
