CGCircuit – Advanced Destruction Series: Lightning Strike

欢迎来到高级破坏系列：雷击

• 创建地形

我们将在 Houdini 中从头开始创建整个场景，包括所有效果、几何和合成。
我们将首先使用高度场工作流程创建地形。
我们将使用多种切割技术仅在我们需要的地方获得断裂的碎片。
对于模拟，我们将创建一个自定义矢量来驱动我们的棋子移动。
然后我们将创建一些小的岩石碎片，我们将它们添加到我们的模拟之上，以增加更多的变化和真实感。

• 闪电特效和光线

对于闪电，我们将以各种方式创建几何图形。我们将结合使用 POP 模拟、
复制到点技术和属性 vops 来完全控制闪电。
从我们的碎片中，我们将创建一些体积射线以添加到闪电之上。

• 碎片烟雾和污垢

最后，我们将使用我们破碎的几何形状来创建烟雾碎片和另一层颗粒，这些颗粒
本质上将充当污垢。

• 渲染和合成

在渲染部分，我将介绍如何为也包含 AOV 的每个图层设置不同的渲染，
以完全控制我们的每个元素。
在 Nuke 部分，我们将把所有东西放在一起来完成最终的外观。这部分将相当
简单，包含偶尔的提示和技巧，以及我每天使用的一些我最喜欢的节点。
使用的工具：Houdini、Houdini 19、NUKE

Title: CGCircuit – Advanced Destruction Series: Lightning Strike

Info:
Welcome to Advanced Destruction Series: Lightning Strike

• Creating the terrain

We will be creating this entire scene in Houdini from scratch, including all the effects, geometry, and compositing.
We will start by first creating a terrain, using the heightfield workflow.
We are going to use multiple cutting techniques to obtain fractured pieces only where we need them.
For the simulation we will create a custom vector that will drive the movement of our pieces.
And then we will create some small rock debris which we add on top of our simulation to add more variation and realism.

• Lightning FX and Rays

For the lightning we will create the geometry in various ways. We will use a combination of POP simulations,
copy to points techniques, and attribute vops to have complete control over the lightning.
From our fractured pieces we will create some volumetric rays to add on top of the lightning.

• Debris Smoke and Dirt

And finally we will use our fractured geometry to create the smoke debris and another layer of particles which
will essentially act as dirt.

• Render and composite

In the rendering section I will go over how we can setup different renders for each layer that also contains AOV’s,
to have complete control over each of our elements.
In the Nuke section we will bring everything together to complete the final look. This part will be fairly
straightforward, with the ocasional tips and tricks, and some of my favorites nodes that I use on daily basis.
Tools used: Houdini, Houdini 19, NUKE
