Increase the Harvest value without up damage

I tried to increase the harvest value proportionally of damage. Present in “CharacterBp_Ankylosaure”
It doesn’t seem work.

I tried to modify the “DmgType_Melee_Dino_Herbivore_Medium_MineStone” for an ankylosaure
I tried to modify the “DmgType_Melee_Dino_Herbivore_Medium_SuperMineStone” for a doedicurus …
It doesn’t seem work.

Is it possible to increase the Harvest of a “DamageType_Harvest…” ? Or increase the Percent of harvest proptionaly of damage ?
