Making parts not render after a certain distance?

Hello so I was wondering how this would be possible, I was browing through roblox when I saw this patch on a game and surprisingly it did fix the lag by a whole lot.

• Power Abilities won't render at far distances (Lag Fixed) ~ Source: Ro - Piece

I was in search of something like this already but never quite knew how to do it, is there any way to change the rendering distance of certain parts and effects?

as incapaxx said, you could use StreamingEnabled but if not, you could use these functions

-- used to check distance from character

local maxDistance = 20

function checkDistanceFromChar(character,part)
	local plr = game.Players:GetPlayerFromCharacter(character) -- gets player
	if plr:DistanceFromCharacter(part.Position) > maxDistance then
		-- put code here
	end
end

-- this works by checking the distance from the character to the part

However, if you want to use CurrentCamera (assuming your using a LocalScript) then you could use something like this:

local maxDistance = 20

function checkDistanceFromCam(part)
	local cam = workspace.CurrentCamera -- gets camera
	if (cam.CFrame.Position-part.CFrame.Position).Magnitude > maxDistance then
		-- put code here
	end
end

-- this works by checking the magnitude of the camera's position minus the part's position
