SimplexNoise

This is a clean, fast, modern and free Perlin Simplex noise function.
If we change float to double it could be even faster but there is no double type in Blueprint
All Public Functions are BlueprintCallable so they can be used in every blueprint

SimplexNoise 1D,2D,3D & 4D
Scaled Version SimplexNoise 1D,2D,3D & 4D
InRange version SimplexNoise 1D,2D,3D & 4D
SimplexNoise Function retruns float value between 0 - 1
SimplexNoise Scaled retruns float value between 0 - scale factor
SimplexNoise In Range returns float value between minRange - maxRange
inFactor value added to all functions to set frequency of the noise [ Recomended values form: 0.1 - 0.00001 ]
GetSimpleNoise1D_EX (float x, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne)
GetSimpleNoise2D_EX (float x, float y, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne)
GetSimpleNoise3D_EX (float x, float y, float z, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne)
GetSimpleNoise4D_EX (float x, float y, float z, float w, float lacunarity, float persistance, int octaves, float inFactor, bool ZeroToOne)

This algorithm was originally designed by Ken Perlin, but my code has been adapted and extended from the implementation written by Stefan Gustavson ([email protected]) and modified to fit to Unreal Engine 4

Problems using Simplex Noise

I've made something from this tutorial using the plugin : https://www.youtube.com/watch?v=1VLVNYR-lRc&t=241s

I managed to update the code as that's a 2018 tutorial, the 2d simplex noise gained a new node since that time, and when I redid the code in a new version of the engine the noise only appears in 2d instead of 3d. Could I get assistance on how to make it work or maybe have assistance with how to make it work? There's absolutely no tutorials and I'm utterly lost

UE 4.26.2 plugin "Berlin Noise" build failure

I imported the plugin "Berlin Noise" into UE4 and it prompts me to↓, What's going on, please?

What is the project license?

Hi @devdad,

Thanks for your UE4 plugin!

I could not find any license in your project, would it be possible to get one added please?

Cheers,

Thomas

Errors when building in Development/Shipping

Hi,
I really like the results with your plugin, but I'm getting some compile errors when I Build in Development or Shipping. Building Development Editor works fine though.

4.22 update?

Got it working with 4.21 but when I'm trying to update the project to 4.22, the plugin fails to compile at launch. Any workaround?

Will not build with 5.1

Hello, looks like this doesn't want to build with 5.1. Trying to upgrade my project and its telling me it can't compile. I just got done cloning what jimshalo10 had in the pull request for 5.0 but that's a no go as well. I was already using this for 5.0 however, its just 5.1 that isn't working now. I understand that this is originally for 4 but considering that it was working on 5.0 is there a way to make this work? I've been trying to compare uplugin files to see what need to but changed so if I stumble into anything I'll update.

Noise generation screws up on pretty big seeds. Output is randomly raised or lowered by large amounts suddenly and small artifacts appear if that doesn't happen. Usually happens when seed is >500.

Crash on loading unreal 4.17 & 4.18 with plugin

Misspelled CreatedBy name in .uplugin file

Just wanted to point out that your name in the Plugins view within Unreal shows as DavDad instead of DevDad. Wanna make sure you get the right attributions :)

In range and Scaled not working as intended.

Hi @devdad,

Just stumbled on a problem here. Idk if this is due to the updates but the thing is the in-range function and the Scaled does not work as expected? It still yields values that are out of range. See attached photos. I'm using the 4.24. I'm not into c++ so I thought it might be helpful to request a check up from the creator.

Thanks a lot!
(attached photos are the screenshot of the yields of the In-range function)
