could someone make a mod where one can
upgrade placable torches/sconces/iron torches for the base with surtling cores or flametal ore, so they burn indefinitely without the need of fuel.
I know there are mods like Eternal Torches which give us indefinite torches already, but they are rather unbalanced in my opinion and i haven't found a mod yet where one has to put some effort into such an infinite light source.
Sconces and iron torches consume less resin indeed, but in a large, fully lit base refilling them is still a tedious task and drains the resin reserves quite a bit.
I think, having to upgrade existing torches with mid-end game materials to get infinite light sources would balance infinite torches a bit while still removing the hassle of refilling them.
