FX Tools

Pivot Painterは、モデルのピボット情報と回転情報を格納する SOP で、ver 1 では頂点データと追加UVで格納していましたが、ver 2 ではテクスチャに格納します。

Makes a Volume or a mesh with constant topology automatically loop. It does so by offsetting the animation by half and cross dissolving the animation onto itself.

Export a destruction sequence to FBX. It takes a packed primitive destruction setup and moves all of the point data up to object level, which allows FBX to interpret that as top level motion. Most game engines will interpret this data as a skeletal mesh animation that can be played back natively.

The Fire Presets Tool wraps up the source, solver and visualisation of a pyro sim making it quicker and easier to generate fire of different sizes from presets as well as use your own source to emit fire from.

Physics Painter は、あるオブジェクト上に物理オブジェクトをペイント配置して重力をシミュレーションすることを可能にする HDA (Houdini Digital Asset) です。前のフレームのシミュレーション結果は、次のイテレーションで何度でも利用可能で、パラメータをコントロールすることで、求める結果を得ることが可能になります。

This quick video shows you how to generate motion vectors using the Motion Vector ROP. I then show you how to use that texture in UE4 and finally explain how we calculate a useful texture.

This video shows one of the ways you could pack multiple pieces of information into a single texture. The idea is to have more control over the look of an explosion in UE4 by separating out normals, emission and opacity.

This is a quick video showing how to export a UE4 compatible vector field. You can use points or a volume as an input and choose the attribute to export.

This is a quick video showing how the Volume Texture ROP can write out a texture representation of a volume to be used with Ryan Brucks' Volume plugin for UE4.

This video will show you how to setup a preview render for pyro (or other volumes) so you can quickly iterate on your shader settings.

Skinning Converterは、トポロジ (topology) 変更の無いメッシュの変形シーケンスをボーンベースのアニメーションに変換するための Houdini Digital Asset (HDA) です。

Initializes the correct attributes on a mesh in order to export a flowmap.

The Static Fracture Houdini Digital Asset (HDA)essentially takes static geometry data from sop level, and separates them into newly generated geometry containers on object level, based on a piece attribute. You can therefore use it to quickly generate static geometry containers for further modifications ob /obj level, or to simply export this as an FBX to be used in The Nvidia Physx lab tool, or any game engine.

シミュレーションデータをテクスチャファイルとして出力することで、頂点シェーダーによる高解像度シミュレーションの非常に効果的な再生が可能になります。
