The Game Jam Starter Kit is a set of procedural game art tools that can be used in the Unreal and Unity game editors. This starter kit provides a variety of bread and butter tools that you can use right away to enhance your game environments. These tools can be used inside these host applications using the Houdini Engine plug-ins which you can install at the same time you install Houdini. Below are tutorials for getting started with Houdini Engine and for each of the tools in the collection.

Note: The Game Jam Starter Kit has been divided into an Unreal and a Unity Starter Kits which you can find here.

    Project assets are broken. If i try to change some parameters unity says "Undefined nodes" pleas checj dependencies etc

    • Simon_V 1 year, 10 months ago  | 

      The Sidefx Labs tools are used in the assets, make sure that you have these tools installed.

    For HDA Rocks - if i try to change it in unity (session wo houdini is established), Unity have pop-up window wich is said "Asset Missing Sub-asset Definitions - There are undefined nodes. This is due to nit being able to find specific asset definitions. You might need to load other (dependent) HDAs first."

    • Simon_V 1 year, 10 months ago  | 

      Indeed, seems the Rock HDA has missing assets. Thanks for bring it up. I will look into updating it.

    Thanks so much! I've been learning so much with just a couple of hours playing around with the parameters. It's very clear and user friendly. It offers a lot of artistic freedom.

  • Simon_V 1 year, 10 months ago  | 

    Rock file has been updated. Feel free to let me know if more issues happen!

  • ing.seprab 1 year, 10 months ago  | 

    Hey, they are great. I wanted to know if there is a way to modify parameters during gameplay without impacting performance?

    • Simon_V 1 year, 10 months ago  | 

      Thanks! The idea of the tools is that they help with building your worlds faster in editor and then bake into static mesh.

  • RasmusHauschild 1 year, 10 months ago  | 

    These are amazing! Great work :) A tutorial on how to make some of these, and the thoughts that go into doing so would be extremely valuable!
    In particular, the platform and foliage tools, since they have such broad use cases. Any chance of that happening?

  • zhenwei2972 1 year, 10 months ago  | 

    Great integration with unity! Had fun playing around with these!

  • ChristopherShaju 1 year, 5 months ago  | 

    please post a houdini tutorial of this;
    how you made these HDA
    That will be very helpful

    Thanks a lot! Great Job!

    Thank you for such awesome tools to work with for beginners like myself.

    I am curious if these .HDA files work in Unreal 4.26.2.

    The default assets in the project display correctly, but when I try to generate my own assets, even within the sample project, I get many "Warning: This node is using an incomplete asset definition. It will not function properly until the asset library containing the full definition is installed" errors.
