Houdini has supported distributed solvers since Houdini 10. This masterclass provides an overview of the current state of these solvers; including the new support for resizing smoke simulations and water tanks in Houdini 15. The first half demonstrates the setup of a variety of distributed effects using shelf tools and HQueue. The final bit dives into technicality and builds a new distributed setup via microsolvers and manually invokes the tracker.

In this tutorial we look at techniques to create interesting zero gravity liquid flip simulations using Houdini.

NOTICE: Houdini 14 - Point wrangle syntax has changed. Put @ in front of global variables, and look out for errors.

Note that I skip an attribute wrangle at 4 minutes in - that is redundant and the distance calculation I did in that I moved to a later step and I do mention that later on in the walkthrough. :)

Sorry for the inconvenience. There is only three passes including Depth,Velocity,RBG in this tutorial without Normal pass.
对不起！视频里是深度，速度，rgb层，没有法线层

视频内是我渲染volume分层的操作，虽说一直用着但是不知道这么渲染出来的分层是否是正确的
