I support this idea; the devs have altered the recipe of low densities for 0.17 (also explained in the same fff as the science pack recipe rework) and that means following them with that would make sense. Thanks!
Also, can you make low densities available earlier in the game, so we can make it for purple science? Otherwise, you need low densities to make purple science, but you need purple science to do rocket research that will unlock the low densities.
Changed the normal low density structure recipe to 20 copper, 2 steel and 4 plastic and for expensive mode to 40 copper, 5 steel and 10 plastic.
I won't do a separate mod as this is merely something for people to design bases earlier for 0.17. If you don't like it just edit it out.
I changed low density to be unlocked with advanced material processing cause I am lazy and this is not meant to replace 0.17.
This will be released with 0.1.3.
Is there a way to force this update to the tech tree retroactively, after researching it? I added the mod to a game after unlocking steel furnaces, so LDS didn't get unlocked.
I might try my hand at editing the current version of the mod, adding LDS to some other random tech I haven't researched yet so I don't have to abandon the save/achievements, but not everyone may be so adventurous. Very much open to pointers, as I've never played with the modding tools before.
EDIT: Fixed it, turns out it was pretty simple to add an entry to unlock LDS, so it got tacked on to Fluid Wagons. Very appreciative of the clean code in your mod and the devs who facilitated it.
