1. What do you want to achieve?
   I’m making a game and I want to know how to make my fog a bit more smooth so when a character enters that area, the fog smoothly changes.
2. What is the issue? Include screenshots / videos if possible!
   I can’t quite tell how to do so.

Can be achieved using TweenService
Tween | Documentation - Roblox Creator Hub

it tweens (smoothly transitions) between values p much

local TweenService = game:GetService("TweenService")

local tween = TweenService:Create(Instance,TweenInfo,{Properties})

tween:Play()
