Looks like this is the part here @howmanysmaII comes in
God tier optimization, as usual. Thanks Lily!
I’ll be pushing your changes to master shortly.
Your changes are live! Thanks for the helping hand! <3

I like this! This would be prefect for a horror a game who thinks that would be awesome?!

Hello. I found a glitch. If the player is using the automatic graphics mode, the rain will not show up at all. I know it is above 8 graphics because the terrain water is still clear.

Not a bug, but rather an annoying feature of the way Automatic works. It doesn’t tell you what it’s being set to, so you have to just assume the worst or you’ll run into problems if it assumes high settings and is really low.
This is very annoying API behavior and developers have been asking for it to change for nearly half a decade at this point. Support a feature request!

I took the script and made it into a module so that you can Enable / Disable the Rain effect during the game, You can also change the settings of the rain during the game.
Module:Enable(Optional Settings) will enable the rain and if the Settings are given it will update the settings of the rain, If settings are not given it will continue to use the previously given settings or the default if non were given.
Module:Disable() Disables the rain
Module:SetSetting(Setting) will change the rain settings to the given settings, Not all settings have to be given.

--FEATURES--
Creates droplets of "water" on the screen, with a distortion effect, giving great immersion
for games that have rainy environments.
Droplets will not spawn if the player is indoors or under cover of some sort.
Droplets will not spawn if the camera is pointed down, as that is avoiding "getting rain in the eyes".

THIS PRODUCT RELIES ON GLASS MATERIAL, THUS SHARING ALL THE LIMITATIONS OF GLASS.
Non-opaque objects are currently not visible through glass.
This includes, but is not limited to, transparent parts, decals on transparent
parts, particles, and world-space gui objects.
Additionally, it only looks right for users with graphic settings of at least 8.
Hence, I've set it to only spawn droplets if the user has the graphics set high enough.

Update!
- Uses object pooling to avoid creating and destroying so many parts constantly
- No longer uses Welds, uses WordRoot:BulkMoveTo instead
- No more TweenService usage
- Adjustable update frequency
- Better performance (getting 300FPS in the demo place on my laptop!)
- Neater code
Also put together a proper Rojo compliant repository instead of that one random .lua file.

Update!
- Now a module instead of LocalScript
- Added
ScreenRain:Enable(settings?) - Added
ScreenRain:Disable() - Added
ScreenRain:Configure(settings) - Tweaked the transparency values for nicer effect
This update makes it easy to have weather systems and zone areas since you can now easily turn rain on and off and configure the settings on the fly!
If you want the behavior from before this update, your LocalScript should just look like this:
local ScreenRain = require(script:WaitForChild("ScreenRain"))
ScreenRain:Enable()

What do i put in the ScreenRain:Enable(setting) what do I put in the setting place?
You can put in a dictionary containing any of the settings that you wish to change from the defaults, although it is not necessary if you don’t wish to change them. Note that you do not need to include all the settings, only ones that you wish to change. Below is an example (using the default settings) of an input.
local Settings: {[string]: number | Color3} = {
Rate = 5, -- Spawn rate (droplets/second)
Size = 0.08, -- Average droplet size
Tint = Color3.fromRGB(226, 244, 255), -- Droplet colour
Fade = 1.5, -- Time to fade out
UpdateFreq = 1 / 45, -- Update frequency
}
ScreenRain:Enable(Settings)
oh okay now i understand thank you!
i won’t stop having this error for some reason:
Here the script:
local RainModule = require(game.ReplicatedStorage:WaitForChild('ScreenRain'))
local Settings: {[string]: number | Color3} = {
Rate = 5, -- Spawn rate (droplets/second)
Size = 0.08, -- Average droplet size
Tint = Color3.fromRGB(226, 244, 255), -- Droplet colour
Fade = 1.5, -- Time to fade out
UpdateFreq = 1 / 45, -- Update frequency
}
game.ReplicatedStorage.Water.OnClientEvent:Connect(function()
local Enabled = true
print('firedlolxd')
RainModule.Enable(Settings)
end)
in a local script

You must use :Enable() not .Enable().
