The Guard Tower project shows beginning Houdini users how to construct game ready units using Houdini. The learning series shows the process of building up the parts and pieces of the props using only Houdini to procedurally produce each asset. Throughout this process you'll get introduced to the techniques of high-res modeling and baking using the toolset that Houdini provides.

You'll also learn how to assemble all the parts and pieces into the final guard tower and its accompanying props, using Houdini, Digital Assets and the Houdini Engine for Unity. By the end of the course you'll have tools that will produce wood planks, ladders, oil drums, sandbags, wall building, and more!  You'll get the “Big Picture” of how to use Houdini for your everyday game production needs. Practical needs.

Before we dive into the construction of the Guard Tower assets, the video above gives you a good idea of the types of assets we will build throughout this course. This course is intended for beginner to intermediate Houdini users who want to learn how to use Houdini Engine. We recommended at least a basic understanding of how to use the Houdini Interface and how to construct some of the basic nodes in Houdini.

1. Building the Ground

To start the Guard Tower scene, you will literally work from the Ground up.  You will learn how to create Houdini Digital Assets and how to import them into Unity 3D using the Houdini Engine!

2. The Wood Wall

In the Wood Wall section of the project, you will create wood planks and posts then copy them to points to create the wall construction. You will learn now to set up the wall using a control curve then how to wrap it up as a digital asset.

3. Sandbag Wall

The Sandbag Wall asset will take things to the next level using VEX and Loops to place the bags in a staggered manner. You will again create a digital asset and its top level interface.

4. Ladder

In this section, you are going to learn how to re-use assets such as the plank and the posts to create a ladder.  By following this workflow you will learn how to dramatically speed up the time it takes to create more advanced digital assets

5. Guard Tower House

In the Guard Tower section you are going to walk through the graph that was built to produce the legs and the house of the final Guard Tower.  At this point in the course you are basically repeating similar steps.  Instead of seeing every node being created, a walk-through will teach you how this asset works.

6. Oil Barrel Asset

In this Oil Barrel section you are going to build a low resolution barrel then use High resolution techniques, learned in the previous lectures, to make the high resolution oil barrel. By the end you will have a complete stacking tool inside of Unity that will procedurally stack oil barrels without any manual placement

      Enjoyed this series so much, thanks. Will the grass blades tutorial you mentioned on the last barrel video be added?

  • Indie-Pixel 6 years ago  | 

    Howdy Little Ninja! So happy you enjoyed the course!! You know, I do need to get that video series completed still. Ill try to get it up in the next week or so! Thanks for reminding me! :-)

  • LittleNinja 6 years ago  | 

    Awesome, thanks.
    Just found the tutorial on Pluralsight, it looks very similar to this one but maybe more extended/detailed? Might signup to take a look at it :)

    • Indie-Pixel 5 years, 11 months ago  | 

      Yeah, the pluralsight course goes through some more techniques and different approaches...Let me know what cha think! :-) Thanks again!

    thank you so much !!

    Any more training like that are welcome ;)

  • Indie-Pixel 5 years, 11 months ago  | 

    You are very welcome Chassaigne! I am so happy you enjoyed the course! the next Course that will be coming out from myself is a course on how to model vehicles in Houdini using a procedural / traditional workflow. Im just finishing up the editing on it now and should release it very soon! Thanks again! :-)

    I can't find the guard tower.hda in the file , is it really there ?


    • Anonymous 5 years, 7 months ago  | 

      It's in the Unity files

  • Indie-Pixel 5 years, 10 months ago  | 

    It should be, but maybe it got missed. Ill have to send it to Side Effects so they have it too. Let me ping side effects and see if they are missing it. Thanks for the heads up! :-)

    You should put up a disclaimer for those of us using Houdini Apprentice. Your tutorial doesn't help us.

  • Indie-Pixel 5 years, 10 months ago  | 

    Howdy Russ! I would like to know more about what is not working for ya? Definitely let me know. Thanks!

  • Anonymous 5 years, 7 months ago  | 

    The skin node in the guard tower is not working as expected in H17. Is there a discord or a forum for discussions about these tutorials?

  • flashpapergrind 5 years, 7 months ago  | 

    In response to Russ (sorry for the necro but this may help fellow Apprentice users):

    Houdini apprentice doesn't allow the use of Engine Plug-ins or the creation of .hda's. Apprentice saves digital assets as .hdanc and Houdini Indie saves them as .hdalc.

    This tutorial is incredibly helpful but only to those with Houdini FX and Houdini Core.

    Oh yeah, this track is solid and informative, thank you so much for making it available to subscribers. :)

    Simply amazing!
    I love your tutorials, I'd pay for them without thinking twice

    Keep doing your awesome work :D

    I am having issues with part 11, layout of wall. when I use the attribute wrangle the polygon disappears using the expressions
    @P.x = rint(@P.x/2)*2;
    @P.z = rint(@P.x/2)*2;

    if I use a number less than 2 on expression @P.x/2 then a square polygon shows.

    • bobc4d 4 years, 5 months ago  | 

      never mind, got it figured out. I was zoomed in too much

  • guillaumeayad 4 years ago  | 

    I am super grateful Kenny, thank you :)

  • Papagodzilla 3 years, 8 months ago  | 

    I am trying to learn the basics of houdini and its unity engine to see if the software is what my next project needs.

    This tutorial seems like the best thing out there to have a global overview and learn the basics. But the apprentice software and engine doesnt seem to work properly in unity, at least not for following this course.
    Is there a way to follow it for learning purposes ? If the tool is what i need, i will gladly invest to integrate it in my project, but as an indie dev, i cannot spend hundreds of dollars without knowing if the software is what i need.
    it is confusing, why isnt there a trial version of the indie software ?

    thank you
