Next episode: kzbin.info/www/bejne/mJmyk6Rsa6aMa6c Please let me know was this video helpful for you and did you have any bugs or other problems?

[@jakubhovorka8754]

Hi, I've run into a issue at 2:40, even after following the instructions visual studio kept complaining about not being able to open the #include file. To fix this I had to go to the projects folder and on the .uproject file click the option "Generate Visual Studio Files" and it worked. Thanks for the great video!

[@fetiska]

@@jakubhovorka8754 Thank you very much for sharing this problem and especially for telling the solution! Your comment will be very helpful for those who also have this problem

[@PoliticalPluralist]

Protip for anyone with a potato for a PC, setup unreal to work with VSCode, a little bit of setup but running both Unreal and VS is not necessary, you can run something much lighter. Very snappy tutorial. Very helpful. Blueprints are super cool but you end up making a wordpress site stringing 47 plugins together to avoid writing some basic code. Glad I found someone doing c++.

[@fetiska]

thank you for the tip and for the feedback!

[@fetiska]

Everyone, I want to say sorry for not making publishing any videos for so long, but I haven't abandoned my channel, I have been working on a new video, but I didn't thought that it would take so much time. The new video will be in a week or so and it won't be connected with procedural generation tutorial, but a video after the following video will be a new part of the tutorial. Thank you all for almost 75 subscribers!

[@austineldredge8003]

This is a really great tutorial and helped me understand the ProceduralMeshComponent way better, thankyou

[@fetiska]

No problem) Thank you for watching!

[@stunthumb]

This series is so damn useful and clear - I wish other Unreal tutorials were as concise and not simply trying to sell a plugin. Thank you, this really helped me escape from using clunky blueprints to do this stuff. I'd say it even serves as a good introduction to starting a new C++ Unreal project, bravo!

[@fetiska]

I am really happy these videos are useful for you, thank you for your feedback!

[@irtezamasud1079]

dude. you are awesome. you made the very complex thing easy. didn't know unreal has specific special class for procedural mesh. coming from unity It seems very informative and flawless.

[@fetiska]

Thank you for your feedback! By the way it’s pretty uncommon to see someone who came from Unity

Hey, your tutorials so cool. Would be nice to see more👍

[@fetiska]

Thank you! I am going to keep working on them

[@lukeblackstone]

Hey just wanted to let you know that this tutorial is one of the best that I have watched on Procedural gerneration. I am currently in school for a gaming degree and this one video is better than the tutorial and lessons that the class has and is currently teaching. I have linked this video in my class discussion, so that hopfully you will get more views. Keep up the good work and thanks again for the great video!

[@fetiska]

I am really happy to hear, that my tutorial is helpful for you! Thank you very much for your feedback and for sharing this video, I will definitely keep working!

Hey! This is nice :) Much more better than me.

[@fetiska]

Thank you, but your videos are also great)

[@lucascavallari8489]

Seems very nice! But do you also know how to make a quad tree? Because I believe it would be too heavy and cost performance for rendering all these vertices at once. Unreal landscape quad tree seems very interensting also

[@fetiska]

I know that quad tree can help a lot to improve performance, but unfortunately i have no experience with it, sorry for that Some other things that can boost performance are LOD, hiding far chunks, multithreading Thank you for watching and for suggestion!

[@rickfuzzy]

Awesome tutorial.

i dont't know if it is comfortable for U, but u have 82% scale of text in visual studio. i was surprised, but its first time i choosed 1080p instead of 720p quality

[@fetiska]

sorry, for small scale, it's pretty convenient for me, but i will address that in future videos

[@BlanchCat]

Do you mind sharing if you use any extensions for syntax highlighting, etc in your Visual Studio editor?

[@fetiska]

I am just using a regular Visual Studio 2022, without any extensions. I set it up using the guide below. There is an extension for VS called Visual Assist which, as far as I know, make VS work faster with Unreal Engine, but it's paid and has only free 30 days trial docs.unrealengine.com/5.1/en-US/setting-up-visual-studio-development-environment-for-cplusplus-projects-in-unreal-engine/

[@doctorblaze8754]

The funniest starts when it goes to LODs XD

[@fetiska]

Actually, as far as I know, Procedural Mesh Component doesn't support LODs and it is one of it's disadvantages

[@doctorblaze8754]

@@fetiska maybe it's possible by decreasing mesh resolution depending on distance. But I do something like you and the hardest part is foliage

[@fetiska]

@@doctorblaze8754 as I understand it, you want to spawn some mesh on your landscape procedurally, right? If so, you need to take point with random X and Y coordinates in the area you want the mesh to be spawned, but for Z coordinate, you should set very high value (something like 999999999). Then you should make ray cast from your point to your terrain using LineTraceForObjects method (for end X and Y coordinates set your point X and Y coordinates, but for Z set 0). This method returns hit result and in hit result there is an output called impact point. You just need to take impact point location and set it for your mesh and then repeat all of that depending on how much mesh you want to spawn

[@doctorblaze8754]

@@fetiska or, instead of "high" ray cast, I can use linear interpolation and landscape heightmap.

[@fetiska]

@@doctorblaze8754 yeah, it seems your approach also should work)

hey, I can't find the lighting settings to copy in the default levels, I tried using the "Basic" and "Open World" lighting configurations but they look different.I also went into the Starter content Minimal_default level but most of the settings are missing since I'm using UE 5.2.1. What lighting settings can I use?

[@fetiska]

Actually I used lightning from Minimal_default. What settings are missing? It shouldn’t look very different even if you are using ue 5.2.1

[@xyr0sTv]

@@fetiska I'm not sure if any of these changed name, but this is what you have and what I have. In your version you have: - *-Light Source-* - *-SkyLight-* - SphereReflectionCapture10 - Atmospheric Fog - BP_Sky_Sphere - *-GlobalPostProcessVolume-* - SphereReflectionCapture In UE 5.2.1 I have: - ExponentialHeightFog - *-Light Source-* - *-PostProcessVolume-* - SkyAtmosphere - *-SkyLight-* - SM_SkySphere - VolumetricCloud

[@fetiska]

@azoicxx you are right, some elements are pretty much the same, just with different name: PostProcessVolume = GlobalPostProcessVolume SM_Sky_Sphere = BP_Sky_Sphere I think I just didn’t copy everything from default scene, so you can use them and everything should be fine. Also you can play around with the parameters if you don’t like how it looks. Keep in mind that lighting has no effect on terrain generation

[@xyr0sTv]

@@fetiska Thanks!

[@fetiska]

@@xyr0sTv no problem

[@moonshot3159]

bro what if I wanted to use your technique to make an infinite voxel terrain? How would you do it in general concepts? I'm following a tutorial by Penny de Byl to make minecraft clone but it's in unity. Tell me if my guess is correct. -Triangle into cubes into chunks -Cull the invisible faces -Use noise for the terrain

[@fetiska]

yes, seems you are right

[@User-cn2qj]

can you do an tutorial when colapsing with a Trigger, new terain spawns?

[@fetiska]

It should be pretty simple: you need to use OnOverlapBegin() in your trigger actor. Inside this function call SpawnActor() and pass your terrain class as the first argument

[@User-cn2qj]

@@fetiska woudn't the new spawned terain spawn inside the already spawned terain?

[@fetiska]

@@User-cn2qj you can specify any location you want inside SpawnActor() function

Try generating Visual Studio project files and please let me know if it resolves the issues

[@stunthumb]

I had a similar issue, then tried adding that to the public dependancy part of the build.cs file instead and it worked... I added it to the end of this line: PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay", "EnhancedInput", "ProceduralMeshComponent" });

[@fetiska]

@@stunthumb thanks for sharing the solution!

@@deadlyremix4115 Not sure... this is exactly what I have: PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay", "EnhancedInput", "ProceduralMeshComponent" }); Worth a quick double-check... not sure what else would cause that, I'm a noob unfortunately.
