Houdini tutorial where you learn how to make a house generator based on modular models. The tutorial is for intermediate users of Houdini.

Generator is very useful when to use in game engines like Unreal engine 4.

    Nice tutorial Simon, I have a question about "L_System". What is the expressions do you use for randomize Generations and Random Seed?
    Thank you in advance for your feedback.

      Hey Emmanuel, There are no special expressions in the random seed , these are link/references to the controller. By default if you fill in the base rules shown in the video the random seed slider in the L-system will work and give random variations.

    Hi Simon, in this tutorial how you copy the reference of your asset from unreal to houdini like UE4 material & asset so when you imported the HDA in UE4 your HDA has automatic material assign to them and asset too.

      You can use attribute instancing, with that you can instance a model or even a blueprint from unreal on the points. So your output is only points (or called pointcloud) with data referencing to the model to use in Unreal.
      Here is some info on it, I also often do this in tutorials. https://www.artstation.com/siver/blog/e3be/houdini-blog-37-unreal-instancing
