@davidoaken2786 wow, I didn't expect you to watch my video! You are definitely right! I updated the description. And thank you again, you saved my time and the time of the viewers)

Tbh, i found your video when i was trying to remember how to update this plug in haha, thankfully i eventually remembered. :)

Watched the previous videos...and i have to say...thats what im looking for, for month! Very well explained and gives a great start into random generated terrain. Keep up the great work, im really looking forward to the next episodes!

[@fetiska]

Thank you! I've already implemented infinite generation. Unfortunately I don't know when I will make a new episode, but I published the code in my Discord ( discord.gg/zyYcJMFkXe ), so you can check it out if you are interested

Is there any version of the Perlin Noise Plugin for 5.4?

[@fetiska]

yes, please check this: kzbin.info/www/bejne/Z3-kd6mNlLybf68

[@leogenot1783]

Hey man, thank you so much for this series, I actually can't get the project to work on Mac, seems like the plugin isn't working correctly, the blueprint doesn't seem to find the "2D Perlin Noise" node, but it's working perfectly on Windows...

[@fetiska]

According to the marketplace page (link in the description), the plugin doesn't support mac. If you want to work on Mac, you can either try to copy plugin code (the plugin code is actually implemented in 2 files: .cpp and .h), or implement Perlin Noise by yourself (if you like to suffer). To copy plugin code firstly you need to create a new C++ class in UE. When you create new C++ class you actually create 2 files YourCPPClass.cpp and YourCPPClass.h. So then you should go to YourCoolProject/Plugins/PerlinNoise/Source/Perlin_Noise and there should be 2 folders: Private and Public. Go to the Public folder, open Perlin_NoiseBPLibrary.h and copy all the code to YourCPPClass.h. After that open Perlin_NoiseBPLibrary.cpp located in the Private folder and copy all the code to YourCPPClass.cpp. It should work, but tell me if you have any problems

How now to round the landscape, make a planet ?

[@fetiska]

Oh, it's actually way more complicated than just "rounding". Moreover we can't use a common sphere, instead we need to create a sphere from a cube (I know how strange it sounds). Sebastian Lague explained it pretty well (link below) kzbin.info/aero/PLFt_AvWsXl0cONs3T0By4puYy6GM22ko8

Thank you very much for that video! I have been looking at how to generate terrains (without voxel plugin which is expensive) and this is really good. I just have a problem: when I try to go over 500 in both xsize and y size, one of them gets limited. Any idea why ?

[@fetiska]

Thank you! Click on your variable in Blueprint and inside it's details check if you typed something into Slider Range or Value Range

[@bizouardpaul848]

Thanks for the answer. I checked and it's not that. I will keep investigating

none of the links lead to the plugin your telling me to download and I'm confused

[@fetiska]

I am so sorry for this! I fixed it, please try now. Can't thank you enough for telling me about that!

[@null643]

Would it be possible to achieve a similar result without using a plugin? For a mod I'm limited to blueprints only in the editor I'm working in so no plugins allowed. I understand if it's not possible though.

[@fetiska]

You can write your own Perlin Noise function. It can take a lot of time and effort, but it's the only solution I see. I am curious what's the game are you creating a mod for?

[@null643]

@@fetiska Thanks, I'll look into the options. The game is Squad and modding is fairly restricted.

[@fetiska]

@@null643 oh, I know Squad, but I didn't know it's made with Unreal

[@null643]

@@fetiska I'll probably scrap the idea XD. Replicating this seems impossible to me anyways, would end up with different landscapes on the server and connected clients.

[@fetiska]

@@null643 I came up with much better solution. If it's a C++ project, you can just copy the plugin's code to your project. I explained how to do this in my reply to Léo Genot comment under this video. Tell me if the solution works when you chek it, please
