Perlin Noise Generation

[latent kiln]

Script

local Size = 500
local Resultion = 100
local Amplitude = 10
local Frequency = 3
-- DONT SET IT TO 1024 OR HIGHER IF YOU DONT WANT A DESTROYED PC

function NoiseValue(X,Z)
    local Noise = math.noise(X/Resultion*Frequency,Z/Resultion*Frequency)
    Noise = math.clamp(Noise,-0.5,0.5) + 0.5
    return Noise
end
if not game.Workspace:FindFirstChild("NoiseTerrian") then
    Instance.new("Folder",workspace).Name = "NoiseTerrian"
end
for X = 0,Size do
    for Z = 0,Size do
        local Height = NoiseValue(X,Z)
        local Part = Instance.new("Part",workspace.NoiseTerrian)
        Part.Anchored = true
        Part.Size = Vector3.one
        Part.Position = Vector3.new(X - Size/2,Height * Amplitude,Z - Size/2)
        Part.Color = Color3.new(Height,Height,Height)
    end
    game["Run Service"].Heartbeat:Wait()
end

yea.

real

Add octaves

[latent kiln]

octaves?

[latent kiln]

what are those

what are octaves???

[uncut mist]

idk

[latent kiln]

well

do you like the terrian?

@topaz moth what are octaves

[topaz moth]

Imagine overlaying noise maps

With altering frequencies

[latent kiln]

im not a region expert

well

thats impossible to add ngl

[topaz moth]

No?

[latent kiln]

well

how do we get a region to have different frequencys

in 1 script

like how?

if it is possible to add its gonna be like 1000+ lines longer

wait

i just realised

[topaz moth]

Nono

It adds like 15 lines of code

4 - 5 is gonna be variables with amplifiers

Like lacunarity, gain, fbm

[latent kiln]

this has 4 settings and im sure you can tune them to your liking

[topaz moth]

Yeahyeah

Octaves just adds detail

[latent kiln]

well its not nessasary

[topaz moth]

I know

[topaz moth]

It just makes it look a bit nicer

[latent kiln]

well i made script under 10 minutes and i was running it battery powered and it took like 40%

[topaz moth]

I like fbm

[latent kiln]

oh god

[topaz moth]

This was on a small scale but on a large scale it can make amazing hills and valleys

With alterations

[latent kiln]

i dont get how i can

i dont get how i can possibly do that

im not that advanced

[topaz moth]

This goes through all of that

Every single thing

[latent kiln]

we;;

well

uh

i have no idea why you need detail in a visuliser

[topaz moth]

Ohhh I might be in the wrong channel then

😭

[latent kiln]

its alright

feel free to use the script

[hasty wing]

Layers

[latent kiln]

ok

i need to get it to be a editable mesh but i dunno how

[latent kiln]

do you know how?

[scenic rock]

there are explanations about making oceans with editable meshes and mesh deformation, that might be similar to what you are looking for

on devforum

[latent kiln]

no

im just trying to make terrain

[scenic rock]

i know

but they use editable meshes to make the oceans

so u can just see how they edit the meshes and do it for terrain

because they are editting the vertices to create the ocean and u can edit the vertices to create your terrain

[latent kiln]

but the mesh can be massive like over 4096x4096...

i use 1028x1028 because its very laggy

and its rendering over 12 million triangles

so an editable mesh would be better

[scenic rock]

read what i said

water with editable mesh edit vertices to make the water effect. you can edit the vertices to make terrain

read about the water to learn how to edit vertices

and implement that code into your terrain system

[latent kiln]

ok'

[pure snow]

Tldr doing perlin noise generation requires you to understand what it is and how to fine tune it.

[topaz moth]

Do it like chunks

Instead of a mega mesh

[latent kiln]

i dont know exactly how to do chunks

im not a perlin noise expert

[hasty wing]

It’s the exact same

ChunkCenter + vector3.new(x,0,z)

Then use that for Perlin noises xy argument

[latent kiln]

ok fine
