Houdini Niagara插件与UE4的特效交互Houdini to Niagara

Houdini to Niagara _ Overview

LESSON & PROJECT FILES: sidefx.com/tutorials/realtime-fx-with-niagara-ue4/
Learn how to use the Houdini Niagara Plug-in to bring point cache data saved out as a JSON file into UE4’s Niagara system along with attributes such as age, life, id and color. These point caches can be static or animated point clouds created using procedural modeling techniques or using Particle, FLIP Fluid or Rigid Body simulation tools. Here are four lessons that explore different kinds of FX.

了解如何使用Houdini Niagara插件将保存为JSON文件的点缓存数据以及年龄，寿命，ID和颜色等属性带入UE4的Niagara系统。这些点缓存可以是使用过程建模技术或使用“粒子”，“ FLIP流体”或“刚体”仿真工具创建的静态或动画点云。这是四节课程，探讨了不同种类的FX。

Houdini to Niagara _ Pt1 _ Particles

LESSON & PROJECT FILES: sidefx.com/tutorials/realtime-fx-with-niagara-ue4/
Learn how to take a particle system from Houdini into UE4 using the Niagara plug-in. Learn what Niagara nodes are available in UE4 and how to get attributes from Houdini into the Niagara system for processing.

了解如何使用Niagara插件将粒子系统从Houdini引入UE4。了解UE4中有哪些Niagara节点可用，以及如何将Houdini中的属性获取到Niagara系统中进行处理。

Houdini to Niagara _ Pt2 _ Volumes

LESSON & PROJECT FILES: sidefx.com/tutorials/realtime-fx-with-niagara-ue4/
Learn how to derive a particle cloud from a volume in Houdini then transfer that into UE4 using Niagara. You can then use sprites to bring back the smokey nature of the sim and achieve a 3 dimensional smoke effect.

了解如何从Houdini中的体积导出粒子云，然后使用Niagara将其传输到UE4。然后，您可以使用Sprite来恢复SIM卡的烟熏性质，并实现3D烟熏效果。

Houdini to Niagara _ Pt3 _ Impact Data

LESSON & PROJECT FILES: sidefx.com/tutorials/realtime-fx-with-niagara-ue4/
Learn how to use impact data generated from an RBD sim to spawn particle sims to add smoke and debris to the destruction effect.

了解如何使用从RBD模拟生成的碰撞数据来生成粒子模拟，以将烟雾和碎屑添加到破坏效果中。

Houdini to Niagara _ Pt4 _ Interact with Baked Particles

LESSON & PROJECT FILES: sidefx.com/tutorials/realtime-fx-with-niagara-ue4/
In this lesson, you will learn how to get interactivity between a baked particle cloud and the Niagara particles. Here you will instance toy bricks to the point cloud then create a system where a character in motion will reconfigure the bricks to build a walkable bridge.
