本教程是关于Houdini和Nuke雷击闪电破坏视觉特效制作视频教程 Advanced Destruction - Lightning Strike,时长:7小时32分,大小:4 GB,MP4高清视频格式,教程使用软件:Houdini,Nuke,附源文件,共56个章节,作者:Voxyde,语言:英语。
创建地形
我们将在 Houdini 中从头开始创建整个场景,包括所有特效、几何图形和合成。
首先,我们将使用高度场工作流程创建一个地形。
我们将使用多种切割技术,只在需要的地方获取碎块。
为了进行模拟,我们将创建一个自定义矢量来驱动碎块的移动。
然后,我们将创建一些小的岩石碎块,并将其添加到模拟的顶部,以增加变化和真实感。
闪电特效和射线
对于闪电,我们将采用多种方式创建几何体。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。
我们将利用碎块创建一些体积射线,添加到闪电之上。
碎片烟雾和泥土
最后,我们将使用碎裂的几何体来创建烟雾碎片和另一层粒子,这层粒子实质上就是泥土。
基本上将充当泥土。
Redshift 渲染和 Nuke 合成
在渲染部分,我将介绍如何为每一层设置不同的渲染,其中也包含 AOV、
以完全控制我们的每个元素。
在 Nuke 部分,我们将把所有内容整合在一起,完成最终效果。这部分将相当
的技巧和窍门,以及我日常使用的一些我最喜欢的节点
Description
Note: Several lessons are available for free and I encourage you to check them out.
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.
