Houdini で列車の衝突をシミュレーションし、頂点アニメーションテクスチャで Unreal に送信する方法について説明します。列車メッシュをフラクチャとシミュレーション用に準備する方法、シミュレーション準備ができたら、頂点アニメーションテクスチャで、シミュレーション結果をメッシュとテクスチャとして保存し、Unreal シェーダとして設定し、変形を再生する方法について学びます。

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。

    Im a little confused by the last video. Are we supposed to have access to Steven's Unreal level? Because I cannot find it in the project files.
    Or do we need to install some sort of plug-in to get access to the "Scripted Asset Actions" and the Special material node

    • StevenKnipping 8 ヶ月, 2 週間 前  | 

      Yes, I think the Unreal map is supposed to be included. Also you will need to install the Houdini Engine plugin to see the Scripted Asset Actions as well as Soft Body Deformation material function.

    How do you get the MF_VAT_SoftBodyDeformation node? I have installed Houdini Engine H19.0.622 for UE5.0 and i only have the MF_VAT_Soft node that doesnt have the same settings as you use.

    Hey, there seems to be something wrong with the archive, I'll see if I can get SideFX to update it. Sorry about that!

    Seriously great tutorial! Thank you

    For anyone else confused about how to get the scripted action and MF to show up properly, you need to copy the plugin contents to your Project folder:

    1. Make sure there is a Plugins folder next to the Content folder in your Unreal project directory. If the Plugins folder does not already exist, create one. (Your project directory is where the <YourProjectName>.uproject file is located.)

    2. Copy the SideFX_Labs folder (...\Program Files\Side Effects Software\sidefx_packages\SideFXLabs19.0\unreal\VERISON#) and paste it inside the Plugins folder mentioned in the previous step. (The SideFX_Labs folder is where the SideFX_Labs.uplugin file is located.)

    3. Your plugin is now ready. Launch your Unreal project and you should immediately have access to the Material Functions, Scripted Actions, etc. provided by the plugin. (With the project open, you can verify the plugin is successfully enabled by searching for "SideFX Labs" in Edit > Plugins.)
