Project Titan での環境作成では、ケーブルが大きな役割を担いました。このレッスンでは、様々な太さのケーブルの集合を作成し、それらを垂らすシミュレーションの実行方法を学習します。この設定は、Houdini デジタルアセットにまとめることができ、UE のエディタ内でのケーブル設定に使用できます。その結果、ゲームプレイに最適化された、環境に手早くディテールを追加可能なケーブルツールが完成します。

Project Titanは、Houdini のプロシージャルワークフローを実制作環境でテストするためのインハウス技術デモで、3D 環境の生成に Unreal Engine 5 の最新テクノロジを活用しています。詳しくはこちらをご覧ください。

    Would the first 4 steps of this process also work with Unity?

    • Simon_V 1 年 前  | 

      Yes the tool should also work in Unity, just remember to input a curve for the tool.

    I'm extremely grateful for this tuts Simon. thanks a lot man!
    Will you make tuts for other stuff too? Loke the building.
    Nevertheless, love you mate!

    • Simon_V 1 年 前  | 

      Thanks, yes more Tutorials will follow!

  • DL_Martin 1 年 前  | 

    Are we getting overviews for each tool of this project? Buildings, character VATs and etc... I really enjoyed this!

    • Simon_V 1 年 前  | 

      Thanks, yes more Tutorials will follow!

    I got a problem when open the file in unreal engine.
    I can't see the Houdini Input. My unreal version 4.26
    Don't know how to solve the issue, it will be grateful if anyone can help me out.

    • Simon_V 1 年 前  | 

      Updating Houdini Engine could solve the issue.

      • wang.ray02jp 1 年 前  | 

        It seems to be a license problem, but i'm not quite sure.
        I'm using apprentice license, "Houdini Engine for unreal" seem to need a COMMERCIAL license.
        Still, thanks for your reply, really appreciate it.

        By the way. This tutorial is very useful, and instructions are very understandable.
        Is a great start for beginner. Extremely grateful for making these awesome tutorial.
        Looking forward to learning more~

    Wow this is awesome, is there will be tutorials about how all the tools in Project Titan was created ?

  • CaueRodrigues 1 年 前  | 

    Amazing tutorial Simon!!

  • Trogleth 1 年 前  | 

    You guys are heros! I love Houdini but as a complete noob I was having a lot of trouble!! Thank you so much for this!!!

  • DirtPizza 1 年 前  | 

    For some reason I stop seeing my Spline control points after I open the Sessions Sync. Is there a way to get them back?

    • DirtPizza 1 年 前  | 

      Oops, was in game view....

    Such a great course easy.

    One question though, do collisions work with UE4 landscape instead of the floor mesh?

    • desolas 12 ヶ月 前  | 

      I wanted to add that it was easy to follow, but it seems like one of those things that are hard to master with all these different systems implemented.

    Thank you for the awesome tutorial!

    Everything with the cable creation and hda setup seemed to go correctly.
    But I am stuck, after bringing the asset into unreal 5.

    I cannot edit or see the curve points after selecting "curve input" and my geometry looks super simplified compared to the one in Houdini ( less cables, less twists, too fat ). But the main thing is that I just don't understand how to access the curve and then make the cable flow where I want it. I don't see any vertices or curves just the geo.

    Any help is much appreciated.

    • 2765987908 5 ヶ月 前  | 

      Did you get the solution?I get into the same trouble.

  • GDonkey 11 ヶ月, 3 週間 前  | 

    New day and now the curve is showing itself. Hahah. Never mind. Everything is working great thank you.

  • VladislavK 11 ヶ月, 3 週間 前  | 

    Hi Simon, this is great! Thanks for sharing this tutorial! Just as a side note, you could also change the simulation type to Quasistatic and control the frame number from there. It would recook and update the vellum solver automatically on any input change without the need to Reset Simulation.

  • uncleda666 11 ヶ月 前  | 

    I learned lesson 5. Why don't I respond to curve input? It's always Houdini's icon.

  • goodday2ran 9 ヶ月, 3 週間 前  | 

    Hi Simon! I follow the steps of lesson 5 but the cables don't collide. Do you possibly know what is going wrong here? BTW I'm using the project file.

  • Julinoleum 9 ヶ月 前  | 

    Anybody else got a problem with the main cable scaling smaller during the simulation? It's like affecting the pscale but I've been rewatching the setup a good ammount of time.

  • panxinyu1234 5 ヶ月, 3 週間 前  | 

    Hello Simon, I can't find the tutorials and project examples about pipe tools in project Titan.

  • Myria 5 ヶ月 前  | 

    Great tutorial, thanks!

    At 12:20, another solution, instead of going through an Attribute Transfer,
    Just change the Construction methode in the Sweep node to : "Cycle Through Cross Section Primitives per Curve.

  • DoctorClue1024 1 ヶ月, 3 週間 前  | 

    Does anyone have solution to measure unity_instanced mesh's size in Houdini?
    I wand to import ununitize sized object, and rescale it to 1 meter. but match size or getboxsize node doesn't work on that.
