By popular request, I’m sharing a breakdown of a tearing effect using pop grains in houdini. We’ll cover a basic version (tearing a flat sheet) from scratch, then I’ll go over a few variations to generalize the effect to other kinds of geometry. Beginner to Intermediate level – nothing wildly complicated, but a fair bit of vex.

应大众的要求，我分享了使用胡迪尼中的爆米花撕裂效果的细目。我们将从头开始介绍一个基本版本（撕裂平板），然后我将介绍一些变体以将效果推广到其他类型的几何图形。从初学者到中级–没有什么复杂的东西，但是有点烦人。
