    ⁉If you are not seeing the MESH SAMPLER option or it is not working 👉 Enable the plugin "Procedural Content Generation Framework (PCG) Geometry Script Interop"

    Hey there! For the Height to Density, you can use a native node instead of BP node, Copy Attributes, copying $Position.Z (the height) into $Density.
    As for the chain with Density Filter afterwards, you can bundle those two nodes into an Attribute Filter on $Position.Z, and you can either use the height as a parameter, or have a constant threshold :)
    Other than that, good content!

    Always looking out for your videos as they are way more in-depth yet approachable than everyone else I have watched so far, definitely can see a quality bump in the making of this video too, thanks & keep it up!
    Already can't wait for your next PCG video! 🔥

    Awesome Video as usual. I assume the text popups are not done manually.. Bounds Modifier says "Bounce Modifier" on screen.. @ 4:27 .. made me LOL

    • @azielarts

      Haha good catch. Lol Bounce Modifier that's a good one.

    Thank you so much! exactly the info I need for my project. For the meshsampler, is it only bound to the triangles and vertices? What if I an irregular topography (not equally subdivided), is there a way to "scan" the surface it self?

    • @azielarts
      @azielarts  4 หลายเดือนก่อน

      No problem!!
      Hmm you might be able to use the voxel option to do that, though I have messed with that as much 👍

    Is there a way to spawn the points on specific areas by filtering where one based of the materials is applied to the static mesh?

    I’m trying to make a blueprint with a few meshes and a PCG component to spawn foliage on a particular static mesh within the blueprint.
    I follow this tutorial, but i cannot add a tag to the ‘Actor’ of the static mesh i want foliage spawning on (if that makes sense?) i can get it to work using a bounding box, but thats not quite what I want.
    Is there any way to do this? Spawning foliage on a mesh inside a blueprint.
    Thanks

    Question: If I desire Static Mesh A on Normal to Density (1st Node) +1 Z Axis, and Static Mesh B on Normal to Density (2nd Node) -1 Z Axis, how do I accomplish that in terms of wiring, tagging (?) and setting parameters in Add, Density Filter and/or Static Mesh Spawner? Is this explained in the Cave Masterclass? Tutorials are awesome.

  • @Lars_Ekstrom

    Having trouble getting the points to appear, ive used the correct tag, have the mesh i want stuff to appear on chosen in the mesh sampler but i wont see any points appear

  • @red4666
    @red4666 4 หลายเดือนก่อน

    can you have the points inherit the color of the surface they're on? to mimic point cloud? and can these points be manipulated by niagara?

    Have you found a way to set Spatial Noise attributes as PCG settings? Really bugs me that they need to be hard coded

    • @azielarts
      @azielarts  4 หลายเดือนก่อน

      Hey! Yes you can create a parameter to access in an instance. Is that what you are thinking?

    Hello Aziel , really awesome tutorial ! really appreciate u give us such the great contents.
    I have tested to duplicate the scattered mesh , bit it seems will lost the PCG on the duplicate one ,even they have same actor tag on it.

    I was just thinking about adding detail to wood using a simple chip mesh but doing it with PCG, and I found your video perfect timing. I had a question. I'm putting the chips on to a simple rectangle. But I wanted more points on my mesh and I used a duplicate point node after my transform points node to double the points I have. But I have to mess with the location to make it look scattered. Is there a easier way to add more points to my mesh? Thank you.

    • @alex.renderings

      Yo I was wondering the same thing and here's what I found to work: start with a World Ray Hit Query node and then plug that into a surface sampler node. You'll probably have to use a filter tag to make sure the chips don't get scattered on anything, but that should work for you

    Hello! You are the master of PCG so i'm reaching out to you for help.
    I have made a PCG that generates me room each time I open a door.
    I have the locations of the walls.
    My question is: Is there a way to make a World map (Press "M" for map)
    That shows all my rooms? Again I have the walls X and Y.
    I was thinking of using widget with canvas, but I'm not sure and I can;t find any information of that.
    I just have X and Y and I wish to create a world map that changes in game mode.
    Any advise ? Thank you!

    Quick tip for anyone wondering how to increase the number of points when scattering PCG on a mesh: start with a World Ray Hit Query node and then plug that into a surface sampler node and you're good to go

  • @aerospacenews

    🌟Another really good one, Thaddaeus! @azielarts Any idea how much of a performance hit this delivers? I used the other PCG technique you taught on a huge map and when I added my camera I went from 70 FPS to the warning about low memory and very low frame rate. I'm sure I've done something wrong - starting with the map size. I did limit PCG spawn to just visible to camera but not much help.
    Going to duplicate the level/map and on the copy try to apply World Partition to reduce the data load. I mention PCG because I've seen some forum posts that say it is costly. I'm doing cinematics so thought my 64 GB, 3080 box could handle. I guess not.

    • @aerospacenews
      @aerospacenews 6 หลายเดือนก่อน

      @azielarts Thaddaeus - apologies for replying to my own comment but had something very strange happen and could really use some help from you or other users. Opening this 5.1.1 project I've found all the PCG elements missing from both the outliner and the project folders, BUT, the scattered meshes are still in my landscape! I can't touch them or edit or delete them in any way. Can you please suggest a solution to at least delete them without starting the level over from scratch? Thank you! 🙇🏼‍♂

    Hello, I'm using version 5.4, and so far I haven't been able to make it happen. The Mesh Sampler function is not available in the version. Is there any way to replace it?

    • @azielarts
      @azielarts  10 วันที่ผ่านมา

      Make sure you have the PCG mesh interoperability plugin turned on. That is probably the issue.
