I know the VFX artists rushed in to see this.
I was reviewing my aurora borealis tutorial until I realized… It kind of doesn’t look like that.
So, I wanted to move the part that’s emitting the entire aurora far up and make it more accurate but, then it just wasn’t emitting anything. I tried using a script but that didn’t work either. It didn’t even render it in.
I tried searching far and wide, but I found either really unoptimized or unnecessarily complicated solutions. Until I just tried to do it myself. I tried unions, attachments, and this is the thing that worked:
BEAMS
Beam objects are used to… make beams. No, not the ones in structures but like those cool plasma gun beams.
Alright, enough babbling I’ll show you how to do it:
Get a part on any location (preferably close to the player like 0,0,0)
Make it completely invisible
Now, put 2 attachments in it and connect them with a beam.
Put the attachment at the grueling location your client fears. (aka the spot where the particles were struggling to render)
You’re done! Wait… Why don’t I see anything?
So, even if the attachment IS rendered, that doesn’t mean roblox will render the particles. Huh makes sense ig
How to fix this
You just import this simple tiny little localscript into your starterplayerscripts:
task.wait(3)
-- LocalScript (place in StarterPlayerScripts)
local RunService = game:GetService("RunService")
local Players = game:GetService("Players")
local player = Players.LocalPlayer
print("[PFX CLIENT] script started for", player.Name)
local EMITTER_NAME = "EmitterName" -- << change this to your emitter's Name
local maxPerFrame = 6 -- cap to prevent flash-bursts
local useRenderStepped = true -- smoother visual timing
-- Find emitter in workspace by name (first match)
local function findEmitterByName(name)
for _,v in ipairs(workspace:GetDescendants()) do
if v:IsA("ParticleEmitter") and v.Name == name then
return v
end
end
return nil
end
local emitter = findEmitterByName(EMITTER_NAME)
if not emitter then
warn("[PFX CLIENT] Emitter '"..EMITTER_NAME.."' not found. Attempting to pick first ParticleEmitter in Workspace...")
for _,v in ipairs(workspace:GetDescendants()) do
if v:IsA("ParticleEmitter") then
emitter = v
break
end
end
if not emitter then
warn("[PFX CLIENT] No ParticleEmitter found in Workspace. Aborting.")
return
end
print("[PFX CLIENT] Using emitter:", emitter:GetFullName())
end
-- sanity: ensure parent is BasePart or Attachment (per docs)
local parent = emitter.Parent
if not (parent and (parent:IsA("BasePart") or parent:IsA("Attachment"))) then
warn("[PFX CLIENT] Warning: emitter parent is not a BasePart or Attachment; this may not behave correctly.")
end
-- turn off engine automatic emission (we control it)
local originalEnabled = emitter.Enabled
emitter.Enabled = false
local accumulator = 0
local stepEvent = useRenderStepped and RunService.RenderStepped or RunService.Heartbeat
print("[PFX CLIENT] Control loop started. Rate:", emitter.Rate)
stepEvent:Connect(function(dt)
-- re-read rate (so designer can tweak in Studio during play)
local rate = emitter.Rate or 0
accumulator = accumulator + rate * dt
local toEmit = math.floor(accumulator)
if toEmit > 0 then
if toEmit > maxPerFrame then
toEmit = maxPerFrame
end
-- safety: if emitter lost parent, try to refind once
if not emitter.Parent then
warn("[PFX CLIENT] Emitter lost parent; attempting to refind...")
emitter = findEmitterByName(EMITTER_NAME) or emitter
if not emitter or not emitter.Parent then
warn("[PFX CLIENT] Emitter still missing; stopping emitter loop.")
return
end
end
-- Emit (this uses the emitter's configured ranges e.g. Lifetime, Speed, etc.)
emitter:Emit(toEmit)
accumulator = accumulator - toEmit
-- debug: remove/comment this if too spammy
-- print("[PFX CLIENT] Emitted", toEmit, " (acc left:", accumulator, ")")
end
end)
script.Destroying:Connect(function()
if emitter and emitter.Parent then
emitter.Enabled = originalEnabled
end
end)
Okay, don’t kill me but I used chatgpt. Look I’m not much of a scripter and this was the most simple way to do it. And it works! Note: that task.wait(3) at the top is pretty important. Gives the client time to actually load the part and stuff. Increase if needed.
WOO! NOW I CAN SEE MY CRAPPY AURA FROM MILES AWAY!!! ISN’T THAT SOOO COOL??
Alright, but this woud be seriously useful for things like fires since in real life you can see them from pretty far away, but roblox doesn’t really do this.
Oh, and if you didn’t figure it out yet, set the beam’s transparency to 1. Until next time!
