Procedural Landmass Generation (E01: Introduction)

Welcome to this series on procedural landmass generation. In this introduction we talk a bit about noise, and how we can layer it to achieve more natural looking terrain.
A quick summary:
'Octaves' refer to the individual layers of noise.
'Lacunarity' controls the increase in frequency of each octave.
'Persistence' controls the decrease in amplitude of each octave.

Yeah. Look at his recent video. I watched it three times in awe of his extraordinary intellect.

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

[@eggzeatpeggz]

8 years old and still a fantastic video

[@Ctlyst0]

just asking, does it still work in newer unity version?

[@eggzeatpeggz]

@@Ctlyst0 probably not so i just download the version he is using

[@Ctlyst0]

@eggzeatpeggz oh okay i see. I was currently on part 10 and so far so good

[@lcarusLives]

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

[@jairussorensen1526]

For those of you wondering, this whole series still works in 2022.

[@ChunkyPotatoGobrr]

thanks man legend

[@adamarzo559]

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

[@javiercalderonmarquez1181]

This is one of the best tutorial series I've ever seen. Thank you so much for this useful information

[@TylerFerraro]

Your videos are always the perfect balance of theory/concept and actual code. Keep up the great work, looking forward to watching this series unfold.

[@xXWhatzUpH8erzXx]

Sebastian, you're by far the best KZbinr when it comes to making Unity tutorials. Anytime I see a new video on your channel, I get so pumped! You just post the best ideas.

[@upgames1313]

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!

[@Foub1234]

I watched your pathfinding series and was blown away. I am really excited for this series and hope to learn a lot on this subject so I can implement a feature like this in my current project

[@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+

[@pandacommando3540]

This is by far the best explanation of heightmap noise I have ever seen. Thanks! :)

[@ulur]

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

[@peteconquer]

This is one of the best tutorials ever.

[@dmaasin23]

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.

[@nmsenterprise4495]

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.

[@ineeda12step92]

Count me in on Patron. You produce superb tutorials and I very much appreciate you sharing your knowledge in a way that I can absorb. Please keep up the great work!

[@QuickFingersGames]

really great job man, really clear voice recording, and a great explanation of what additional octaves do in proc gen, will be watching this series :)

[@Sycenx]

I never comment on videos, but these are so incredibly good that I have made an exception. Love it!

[@EnricoPietrocola]

That's some signal processing theory explained perfectly in 3 minutes, can't wait for the other videos

[@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!

[@felixmerz6229]

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.

[@GodVenn]

Your videos are really clear, well explained and interesting. I love them, please keep'em coming!

[@MakeWithData]

This is awesome! I really enjoyed the more mathematical analysis, and I can't wait for the next part!

[@John-kl8jt]

[@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.

[@Badders1977]

[@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 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.
