TLDR: I want to show a Vector3, as an arrow, in game
Ive been working on this script for about a week now. I'm trying to create a custom particle system that can do way more then the default particle effect.

Basically what this does is make an array of vectors (function GenerateVectorField), then construct them into a vector field. And spawn particles to simulate on the vector field.
local TweenService = game:GetService("TweenService")
local RunService = game:GetService("RunService")
RunService.Heartbeat:Connect(function()
local particles = workspace.Particles:GetChildren()
local ignore = workspace.Vectors:GetChildren()
for i=1,#particles do
local currentvector = workspace:FindPartsInRegion3WithWhiteList(Region3.new(particles[i].Position - (0.5 * particles[i].Size), particles[i].Position + (0.5 * particles[i].Size)), ignore)
for j=1,#currentvector do
local goal = {}
goal.Velocity = (currentvector[j].Value.Value / 10)
local tweenInfo = TweenInfo.new(1)
local tween = TweenService:Create(particles[i], tweenInfo, goal)
tween:Play()
end
if (particles[i].Position - Vector3.new(0,0,0)).Magnitude > 10 then
particles[i]:Destroy()
end
end
end)
Basically what this does is find a vector that is in range of a particle and set the velocity of the particle to the vector.
All I want to do is visualize the vector field I have.
Ive tried HandleAdornments and setting the orientation to show the vectors but they don't seem to point in the correct direction according to other simulations (Ex. f(x,y,z) = [x,y,z]) or even the way particles move when they intersect (Ex. f(x,y,z) = [sigma * (y - x), rho * x - y - x * z, x * y - beta * z]). I've tried visible VectorForces, which works exactly as I need, but they don't show up ingame so they are completely useless. I've tried hundreds of things but none of them work.

You got it right, though the problem is that orientation and vector forces are completely different. So you cant just set orientation as the vector, or it wont point in the right direction.
