About asking for permission, I know I have to get permission for using assets like models or textures from their authors. But what about some simple changes of existing records in the game? For example, if I want to make a FO4 weapon rebalance mod and think "hmm, maybe I should also buff minigun's damage to 12" after seeing Cupressi's Minigun Damage Increase mod, basically I only change the same record in ESM in the same way as he did, do I have to ask him for the permission?
