So I'm making a modpack using spice of life carrot edition and your config options are confusing to me as i want the player to gain HP whenever they eat enough foods (up to 40 new hearts total but the pack balances this as thats super late game)
I have these set right now:

If true, max health will be capped at 6 hearts and absorption at 2 hearts per limb. If false, the health cap will be much higher (64 hearts normal and 16 absorption)

B:capMaxHealth=false

If true, max health is scaled to your hearts, and the config entries get multiplier to match the max health

B:scaleMaxHealth=true

If true, all usages of setHealth from other mods will be captured. Should not cause any problems, but allow mods like scaling health bandages to apply

B:watchSetHealth=true

But it appears that even eating different foods i'm not gaining new hearts. on my limbs. Could you help clarify what i need to do in order to get this to work?

spice of life carrot edition had an incompatiblity, but it is resolved now.

there is a config option saying natural health regen and set that to true.

where is that option in the config i cant seem to find it
