Your lecture is not only technically excellent but also inspiring. At least for me, you will be remembered as one of the best artists of the 21st century.

This video, around seven years ago, sparked my love of procedural generation, and even got me to start coding, wanting to fiddle with things. It popped up in my recommended feed and I just wanted to give some appreciation to Sebastian for helping me get into coding

Too many wasted searches to find procedural generation, until I found this treasure. Well done sir, it's very clear and understandable. I'm gonna implement this later.

I remember watching this video over 2 years ago while starting to dabble in procedural generation. It opened my eyes how cool and amazing programming and math can be and I haven't looked back since. Thank you for this amazing piece of education and for inspiring me in my journey to learn programming. ps. it's my third time watching the series and I'm still learning more from it!

[@lcarusLives]

I am so hyped for this - hopefully I'll have the time to tag along with this series. Looking forward to it, cheers!

[@ulur]

By far the best video on KZbin about procedural landmass generation!

[@kristianthaler6525]

That fly-over at the start with reflections on the water and all really made me want to learn. And your simplistic explanations are extremely helpful. A+

[@williamdowling7718]

This is the highest quality science concept/math/programming/simulation content on KZbin. Anyone who disagrees can fight me.

[@adamarzo559]

You always come through with high quality informative tutorials. Definitely one of the better Unity tutorial channels.

[@ealy3545]

great introduction. it's nice to see what exactly we are gonna do and get before we start instead of just jumping in a tutorial where you only see the result at the end.

[@John-kl8jt]

Outstanding tutorial. Excellent knowledge of both programming and unity.

[@medoingnerdstuff]

Just wanted to say thanks for this. It's brilliantly easy to follow and has helped me to understand why, when I followed other tutorials on the subject, things weren't working.

[@N0tVen0s]

Oh my god, man you are so cool, even after 8 years this tutorial is the best, thank you so much you are the best too)

[@splintercat7gaming]

This is a really good explanation of Perlin Noise. I had to research this on my own some months ago. This makes it seem so easy. Thanks.

[@filipv4u]

Man I love all your tutorials you're spot on. I'm really looking forward to this one. I would also be really interested in how you would create biomes or caves and place trees or other items in the world, and what we can do to control the generation.Cheers!

[@thecakeredux]

It's been four years, but I can give you a quick, yet unspecific answer: As long as your algorithm is deterministic, you can use it to do whatever you like. Pathfinders, for example, can be used to generate caves, all you need is specify the condition that needs to be met in order for two points to be connected and what condition has to be met for the pathfinder to consider a point as an obstacle to get around, and you can generate caves. Biomes can be created, again, by perlin noise. There is no reason why perlin noise would only dictate height, it can just as well dictate biome.

[@regfinley7111]

Sorry this turned out to be a bit of a novel. So I started this tutorial about 2 or 3 years ago and nailed it! I cant say enough how much I appreciate it. I was a bit bummed out when I notice no water was included. A few years later I decided to tackle the issue my self and put it on the back burner (I got stuck). And dare I say I recently got it working but the only problem is the water is not effected by the lod system due to the Texture2D heightmap generation. So water in the distance is the same as up close which is a minor cost that I will have to pay ;). I kept a eye on the profiler and it runs at a consistent 60 to 100 frames on a 8gig laptop with a gtx960. The problem I was having was when the seams for the terrain mesh are stitched together. Long story short my solution was to duplicate the entire process then insert the word "water" to each script that was used for the mesh generation. I then used a water tile plane as the "mesh container" instead of generating a texture2d with perlin noise. :) I noticed that I was getting errors due to a HeighMap which I changed to WaterMap and it always returned null. And I couldn't figure it out until I commented out the if statement inside of UpdateTerrainChunk() which I changed to UpdateWaterChunk() at if (lodIndex != previousLODIndex) along with one of the last lines of the script at ThreadedDataRequester.RequestData So everything is visible and hidden when it is needed but the lod always stays the same. Not a huge deal as I am Ok with what is happening in the profiler. I realize this is a old tutorial but I don't care. Thank you! thank you! thank you! I will post a video on my personal channel if anyone is interested in seeing how I did it. :)

I was super inspired to start going through this series and after watching this video I decided I need to go and learn more about curves. I remember briefly talking about Amplitude and Octaves in high school. But it's been a while and all these terms are confusing me. You have an excellent teaching style though. I'm afraid I'm just a bit behind.

[@GodVenn]

[@Strongfinger777]

Important Things you should know before starting this Tutorial... 1. There are script changes missing in some of the videos that can cause you headaches. You will need the source code he provides in the notes to compare to your own from time to time. 2. He breaks the Falloff Map feature at the end when he reorganises all of his scripts. It no longer affects the terrain mesh. 3. Everything to do with textures in this tutorial will be useless for a lot of developers, because he hard codes his system to only use the One Shader we create during the lessons. And the Shader in question only supports Albedo maps. No Normal maps or Specular maps, like Roughness, leaving the textures looking very flat, boring and retro. EDIT: 4. He breaks the Terrain cleanup at the end too. He really should playtested his changes at the end.

[@alrogast]

Thanks for the warning. Excellent tutorials, based on them I made the generation of a limited world from chunks. But then I don't understand at all what to do with texturing the world. Could you give advice on which way to look, or there may be links to tutorials on texturing meshes. Thank you.

[@Strongfinger777]

@@alrogast No worries. Unfortunately I just stuck with one built in material with one texture with normal map and roughness, which you can still apply with this system. I just threw out all the texturing and the shader from this tutorial and plugged a preferred material into it, which will still work. But its only one texture over the whole landscape. It works fine for my game, because its set in hell and looks all volcanic, but unfortunately for an earth like world its not appropriate. I tried adding normal map support Sebastians very basic shader, but I couldnt figure it out. Sorry m8. I dont know what else to try. Hollistic 3D has a couple of tutorials that uses a very similar technique for texturing, but its for actual Unity Terrain, not anything else. But at least it had normal map support. :) Oh, another thing Sebastian breaks at the end is the terrain cleanup. Bits start getting left behind again. I dont why he didnt playtest the play mode at the end. Programmers should never assume their code is just going work.

[@chewysnipes6376]

Thank you very much for your tutorials on this subject. The subject matter was great; the presentation was ok. You move very quickly through some topics, often deleting or renaming code in less than a second and immediately scrolling away from what you just did, which makes coding along with you rather tedious, with having to stop and rewind the video to see what you had just done. But all-in-all, a very good tutorial for beginners, and I will continue to follow you to see what else you might come up with. Thanks again.

Very nice and helpful serie ! I'd like to go further by inplementing biome generation but i don't know how to do it. I've thought about creating other noiseMap with different parameters (like FallofMap) but i struggle makin this spawn randomly on the terrain and not in only one chunk. Thanks for the help

[@tacopacopotato6619]

great video, youtube needs more stuff like yours

[@geekygamer3954]

If anyone needs help with understanding this video, try ignoring the red graph. Imagine each octave layer as separate land generations. all that's happening is it's adding the value from the graph, onto the main grid. and the "lacularity" is how much each value is. and each curve. is how much the value goes down. the more curves, the less impact it has because when you hit enough curves, it balances out and becomes an average value. note: lacularity also scales down the graph. so basically its like you're compressing a spring. laid out, the spring is very long and can go very up or down, but compressed it becomes a straight line. persistance is just the multiplier. it multiplies how much each value occurs. it takes the coil, and repeats it. for example, if you have the number 16. with default layering, the single square value is (x + 16). with persistance, it's (x + y(16)) you multiply the 16 by the persistance.

[@geekygamer3954]

for basic understanding (without persistance or lacularity), the graphs are litterally added together. combining the graph: y1 + y2. take the first graph's value and add it to the second graph value. it's supposed to represent the graph getting darker as it gets closed to 1.

[@petrkassadinovich2705]

Thank you Sebastian!

[@dougwarner59]

Even though you never explicitly said so; I assume that persistence should be less than one and Lacunarity should be greater than one to obtain the desired results. Anyway great video and I can't wait to learn more.

[@GregoryTheGr8ster]

I was messin' with this subject in 1994. Sadly, the AI that my game needed was an insurmountable challenge, so I abandoned it. Still, I regret that I did not continue to work on the terrain generation feature. Also, I realized that if I want truly natural terrain, I'd need to become a geologist. I'd need to know densities and other physical properties of the Earth's crust, and also the forces that act upon the crust. That would be a big task.

[@danh9676]

I want to make sure I have this right. Octaves is essentially the number of layers. Lacunarity is essentially the scale of that layer(octave) Persistence is like the opacity of that layer(octave) Is that correct?

[@gaz0z]

If you are to additively combine those 2D layers of height maps in an image processing software. Yes, those would be the exact parameters you'd be playing with.

Been looking into procedural generation and perlin noise to generate height maps for terrains recently and I think this series is exactly what I have been looking for! Also it looks like you textured the terrain by giving individual polygons a color based on their height or noise value, if this is what you used then I looked into it but couldn't find no solution

[@Neronix17]

I was literally just looking into adding this to my project yesterday, so awesome timing. I don't suppose you're covering how to include prefab assets on the terrain? I don't mean generating them like the terrain though, I mean like a predefined object in a specific set of coordinates and having the generation accommodate that object with the correct height of terrain.

[@adamevans1312]

Just a guess but after your noise maps are generated, edit the value for the area you want effected to a constant in a circle radius or something along those lines.
