Houdini碰撞尘土烟雾特效教程 FXPHD – HOU170 – Impact-Based Dust Volumetrics in Houdini从不同镜头的准备和优化开始讲解，到场景烟雾粒子的模拟，比如物体之间碰撞产生的尘土之类的The course begins with preparing and optimizing the assets to ready them for fast iteration during the shot production process.

It then dives into the often scary world of DOPs by building a smoke simulation network, which will allow you to both demystify and master the workflow.

Great care will be taken in studying the crucial step of the volume sourcing emission.

You will see how to avoid stepping, as well as inject as many details in the simulation right from the emission by extracting useful data from the RBD animation.
