@@nicolasseydoux5985 me too, editor scripts were just pure magic to me before this.

Minor bug: when checking the min/max, you should not have an else there (at least for the first value). The first pixel in map should always be both greater than the maximum and less than the minimum. So you could miss the global minimum there.

Absolutely phenomenal tutorial. Truly one of those lessons that makes the work of thousands better.

this might be one of the best tutorials I've ever watched. It's got real MEAT to it, and the concepts are challenging (at least to me), but the explanation is great and the code is clear.

Minor tip: If you're still bothered by the resolution despite all the operations and think it's blurry, the reason is that you're entering pixel values for localScale in your MapDisplay script. The transform values of components in Unity specify their coordinates in the world, not their resolutions in pixels. Therefore, you need to keep the localScale variable lower so that pixels are compressed instead of spread out, resulting in increased resolution. You can achieve this by dividing the height and width variables in the MapDisplay script or passing other variables to the Renderer.

Thank you for making these, you are an amazing presenter of just the thing I need to learn.

Definite the best Tutorial on this subject I have found. Fantastic Work Sebastian !

This is honestly an amazing and educational tutorial.

Your tutorials are always amazing. You're a boon to experience!

This videos are amazing, im don't have any experience in unity, im a programmer. But following your videos now im have knowledge about many things (perlin noise, octaves, frequency, etc etc etc) included Unity. Thanks for sharing, im a new FAN. Where i am in 2016 DAMN!

for the moment, the most difficult code i have seen in unity program tutorials. Thanks!

I don't really know how you came up with this but you are an absolute genius! thank you so much

Thank you! I now have a basic understanding of what "noise" is, and I hope to use this for a lot of games.

Thx,thx!!! Sebastian. I really appreciate your efforts for this goods tutorials. Nice job!!!

If anyone plays around with the noise settings and notices there is a secondary layer of noise, and wants to know how to control that... Just do something like this: Declare a variable for secondary noise scale however you choose, I did this: [Range(0,10)] public float secondaryScale; and then pass it in to the samples under the loop. This allows for some extra flexibility in creating interesting shapes later on. float sampleX = (secondaryScale * x) / scale * frequency; float sampleY = (secondaryScale * y) / scale * frequency; As always, thank you sebastian!

7 years later and these are still the best tutorials out there! Great work Sebastian! For anyone watching this now, here is a fix for the parallax seen at 9:04 when changing the offset: float sampleX = ((x - halfWidth) / scale - octaveOffsets[i].x) * frequency; float sampleY = ((y - halfHeight) / scale - octaveOffsets[i].y) * frequency; Note: This also flips the scroll direction in x and y which makes more sense when you are dragging the values in the editor but might break eventual minimap code etc. If you do not desire this just flip the sign again.

Switching it back to the MapMaterial fixed it so it now shows the correct black values. That was actually pretty funny. I thought it was due to the editor default lighting, directx vs opengl, I was changing all kinds of things trying to fix it! Its ok now though so don't anyone fret! :)

That's a very increadible job. Thank you very much!

Your tutorials are the best.

I was working on a procedurally generated 2d top-down game and was using the default Mathf.PerlinNoise texture with no added processing to generate my terrain. Needless to say, it did not look very good. I tried all kinds of solutions, even switching to cellular automaton generation for terrain, and while it looked better, it did not generate infinitely. Using your tutorial my terrain looks even better and is now generated infinitely. Thank you so much for this!

This is pretty awesome. I was playing around with generating blocks with the map so more granularity in making the noise map is great. Hopefully you go over chunking in the future as that's where I'm stuck when trying to combined the meshes and hit the max vert limit.

I grabbed a bunch of code from github for open simplex noise. I had to remove a bunch of code for 3D and 4D noise, then modified it to make it work. The noise in my implementation is extremely slow. It gives different values than the Unity perlin. When you average the two noises then multiply it by amplitude the results are amazing

Thank you for the great tutorial. Only one that I have been able to find on layering noise to create heightmaps. Currently using it through Java to try to create good Cities Skylines maps. Most on workshop are "my first map" or the really good ones based on a specific location.

Great content! Thank you very much!

Great tutorial as always! One thing I figured out is that you can ditch the custom editor and call GenerateMap from the OnValidate method. Then it also updates when you undo variables changes.

hey its you who asked the question on cubes terrain generation on unity

Just a note if anyone is trying to implement this in a real game that needs to be chunked or tiled in any way, this works only if your noise texture is generated once and then sampled. Offsetting and changing scale will dramatically change the features in the next tile since the average is being calculated locally and offsets are being offset too much. You can see the artefacts as he scrolls through terrain in the video, it is not continuous terrain. Solution is to first change the offsets so they match the scale : float sampleX = ((x - halfWidth) / scale * frequency) + (octaveOffsets[i].x / scale * frequency); float sampleY = ((y - halfHeight) / scale * frequency) + (octaveOffsets[i].y / scale * frequency); and after that you can either remove the scale (not recommended) or you can calculate the max value globally. Since your noise map outputs 0-1 , you can either use geometric series to pre compute the maxValue, or you can just send a dummy value of 1 through the loop, applying the function, and saving the result as maxValue. Another thing is you want to not scale the terrain -0.5,0.5 if you are not working with Z component, if you are, you need to compute the minValue using the above technique.

Thankyou sebastian league very cool 👍👍👍👍👍👍

Three thumbs up! Just awesome!

Great tips!

Once you finish this, you should show us how to add random objects (tree's, etc) in the map as well as a way to use water asset's with this system and if you've ever played rust things like Rad Town's etc.

11:17 you may know this at this point but putting [Min(1)] next to the public variable will also clamp it there.

Great work

I think maybe the offset should also take scale and frequency into account, like so: float sampleX = ((x - halfWidth) / scale * frequency) + (octaveOffsets[i].x / scale * frequency); float sampleY = ((y - halfHeight) / scale * frequency) + (octaveOffsets[i].y / scale * frequency); This way the offset value will scroll/translate through the perlin noise at each octave's own level of detail.

i have noticed that the offsets are not working well. when you're changing them the noise map is not moving but it looks like a layer of clouds moving at differend speeds - this is because the various octaves are not moving as they they should. fixed it with: float sampleX = x / scale * frequency + octaveOffsets[i].x * frequency; float sampleY = y / scale * frequency + octaveOffsets[i].y * frequency;

Well that’s cool. Allows you to see different maps easily.

Nice tutorial sir. :)

thank you.

I believe there is a flaw in the min/max noise height part of the procedure. Because you used an "else if" for the minimum height part, if the first sample happens to be the minimum value for the entire map, the minNoiseHeight value will never be assigned to that minimum because the first sample will always be greater than the initial maxNoiseHeight value and it will not go in to the minNoiseHeight part of the conditional statement. If you make both parts if statements instead of if/else if then it should correct this flaw.

You can now clean up those messy if checks for if a value is [Min(1)]public int mapWidth;

As great this tutorial is, I have a question: is there a way to update the offset in runtime without relying on the GenerateMap function on every frame?

you're just amazing man i wanna know how do you do those things since a year i wasn't able to understand what do you even saying after a year of hard work and shit now i only can understand and be amazed acctually! xD

I find this extremely fascinating. Have you considered changing how the scale should be different for each frequency? Done the way I'm imagining it should look more like your zooming in and out rather than stretching and shrinking. You'll notice when you reduce the noise scale it starts looking like flat noise and when you increase the noise scale it starts looking like one color. Let me know what you think. Thanks for the video.

7:50 It's because 100,000 units is the max width and length of the terrain object.

Should'nt you multiply the octaveOffsets[i].x and octaveOffsets[i].y with the frequency?

I was wondering if eventually you'd show a way to use this for 2D terrains, and would add editors for the final version of your terrain (provided you may like to move the vertices by hand after the generation).

A better fix for both the issue with parallax and the scaling is to not apply the scale the the octaveOffset but only the frequency. Also a tiny nice to have is to flip the y offset so that when you drag the value in the editor up and down will be correct. float sampleX = ((x - halfWidth) / scale + octaveOffsets[i].x) * frequency; float sampleY = ((y - halfHeight) / scale - octaveOffsets[i].y) * frequency;

It's just that further octaves don't get offset properly if you don't multiply their offset by frequency too.

Excellent tutorial. Clear and concise. One question: The *2-1 operation on the noise is somewhat superfluous, no? It normalises to the same terrain topography in the end - just offset 0.5 down? As in, that can be shifted afterwards if needed? Or if not normalised just sneaks in extra amplitude?

Great tutorial up to the point where persistance gets turned into a slider. It didn't work for my version of Unity initially (2019.1.8) but a quick google search revealed a Unity tutorial about sliders in inspector and just modifying [Range(0,1)] to [Range(0f,1.0,)] seems to have made the trick.

Because the min and max can go below 0 and above 1 when you are layering the octaves. For example with a high frequency you could find you get 0.8 for octave 1, 2 and 3 which when added together would give you 2.4. The same can happen in negative. Also imagine if you had an amplitude of 1000 instead of 1, then you would have 2400. It doesn't matter how big or small the numbers go when you are sampling the points, as long as you bring everything back between 0 and 1 at the end while maintaining the proportions.

+Alister Gray That error message means that there should NOT be 8 parameters. Go check the method definition and make sure the parameters you're passing in match up correctly with the method's arguments.

Offset -100,000 to 100,000 works, but no larger, since float only has 6-7 decimal digits of accuracy. You're dealing with fractions of numbers after this. 100,000 is already using up 5 decimal digits, but you're requesting 6, 7, or more. (E.g. 10 million + 1 in float will still be exactly 10 million.)

The else at approx 3:51 will make it so that if the first value generated is the lowest, the normalization will fail. (as the first value will be both the highest and the lowest value seen so far regardless of value, it needs to update both). It should just be a separate if statement.

noiseMap[x, y] = Mathf.InverseLerp(minNoiseHeight, maxNoiseHeight, noiseMap[x, y]); This is making my plane come out just pure white in texture.
