A great way to understand Houdini’s node-based workflow is to explore it in the context of a project. It is important to start learning how to think and work procedurally. In this lesson, you will learn how to create your own custom brickify tool using procedural nodes and networks to define its function and interface.

Along the way you will get to use different aspects of Houdini’s workspace. By learning how to use these UI elements together, you will dive deeper into Houdini’s node-based workflow. The lessons will then give you a chance to put your ideas into practice, which is one of the best ways to learn.

This lesson includes a Step by Step PDF document to help guide you.

This is an updated version of this H19.5 Lesson.

    It's so fast I can't keep up. I can't see anything because it's going too far.

      misunderstood after only watching the video. The PDF is so well organized, I like it! I can't delete the reply, so I'll reply instead

    task was quite straight forward but after smoooth shading at the end, my nuggin on my brick is not quite circular, it has straight edges, ive repeated the lesson and found the same result.

    it seems to happen when i do the last polybevel onto the group :) any help would be great

  • Immy_Raja 1 year, 2 months ago  | 

    i figured it out, i missed a step, when beveling make sure you turn off group selection in the parameter plane, before you select include edges box,

    my point light isn't allowing me to manipulate it

      mine either!!!!!

        Did you switch to shadow mode?

  • leifdux 1 year, 1 month ago  | 

    Interesting, I know everything is wired correctly because I am able to get both the color from the Color Node as well as the Cd attribute with the rubber toy color.
    But...when I do check Pack and Instance, it does not show any color at all (just the grey color you see in clay).

    Did not check Add Shader in the testgeometry_rubbertoy too... Help please...

    • rmagee 1 year, 1 month ago  | 

      Did you change your viewport to OpenGL? There were instructions at the beginning of the first video. That might be causing the issue.

      • leifdux 1 year, 1 month ago  | 

        Thank you for the reply! Yes, not setting viewport to OpenGL was the issue (was set to Vulkan).
        Sorry, I was following the textbook version until I got stuck at this. (I believe the textbook did not mention to set to OpenGL?)

        Is here the best place to reach for Q&As?
        My lego blocks are seemingly too big and is overlapping a lot, I'll follow the video version to troubleshoot.

        • rmagee 1 year, 1 month ago  | 

          Post to the Houdini Learning Material forum and ping me - be sure to include your hip file. That will make it easier to find where things aren't working.

    Thx Rob for a nice tut. I wanna know why you set the attribvop to Run Over: Vertices and then promote them back to Points, couldn't we just read the Cd from the texture and apply directly to points?

  • Emil 1 year ago  | 

    Hi again Rob, I just gave it a shot by using the Attribute From Map node which works directly on points and it kinda replaced those 2 nodes (attribvop and attribpromote), at least visually looks the same.

  • janisfs 1 year ago  | 

    Hi Rob
    I noticed this - the pegboard has an uneven shadow from the figure. There is a shadow on the base, but the tops of the bricks do not have one.
    How can this be fixed?

  • LuzidVision 8 months, 1 week ago  | 

    I really dont think explaining the basic UI stuff in every foundation tutorial is useful? Rather annoying?

    • rmagee 8 months, 1 week ago  | 

      The reason is that we don't know which of the foundation lessons people will start with. So we make sure to make it accessible to first timers in case this is the lesson they start with.

      • LuzidVision 8 months, 1 week ago  | 

        Sounds reasonable, I guessed as much. Still its sometimes a bit frustrating, given how frustrating Houdini can be by itself. When I fight for an hour with a 10 mins segment of a tutorial, starting the next tutorial with repetitive info is somewhat agitating :D

  • LuzidVision 8 months, 1 week ago  | 

    Otherwise great series

  • LuzidVision 8 months, 1 week ago  | 

    feels a little odd to have to select the deprecated option for a quite recent tutorial. is there no way to achieve the coloring with vulkan?

  • LuzidVision 8 months, 1 week ago  | 

    the HDA should be saved with the suffix -deprecated

  • sdeleurere 4 months, 1 week ago  | 

    In lesson 2, Houdini would straight up crash when trying to copy the brick to all those points. I checked my RAM usage and it shot up all the way to 64GB. The only way to fix this is to add the copy to points node manually and enable "Pack and Instance" before connecting the rest to it.
    ( I have a 7900x, 4080 and 64GB ram running Linux Mint)

    • rmagee 4 months, 1 week ago  | 

      Strange - I have less memory than that on Windows and I wasn't crashing. But that was H20.5 and it sounds like you are in H21.

      The way you set it up sounds like the best option. I should recommend to R&D that Pack and Instance is on by default for this node.

    I'm going through this beginner path series in order and in this video I can not for the life of me get the "Copy to Points" to work. Every time I click "Copy to Points" then select "rubbertoy" and hit enter I'm just brought into the rubbertoy's object view. I've watched the video, YouTubes, and read this and general Houdini forum instructions and can not get the "single_brick" and "rubbertoy" nodes to become connected, or merged for lack of a better word, within the object view. Every single time when single_brick is selected and I click "Copt to Points" then select "rubbertoy" and hit enter, it just drills down into that rubbertoy view. Can you help? Was something turned on in one of the first two videos that needed to be turned off in the display settings but wasn't mentioned? Thanks in advance
