Houdini+Nuke石头汇聚特效教程 Gumroad – Magical Rock Assembly – Houdini & Nuke VFX Course

讲解Houdini中制作石头汇聚还原特效，包括破碎特效、自定义粒子运动、烟雾模拟、灯光渲染输出、以及后期Nuke的合成等

Fracture

• We are going to start this course by fracturing our Hand geometry using voronoi and boolean techniques.

Procedural SOP Setup

• After we create our fractured pieces, we are going to set up the assembly animation entirely at the SOP level.The motion of the pieces will be determined by curves that we can art direct and change in real time, without having to resimulate anything.So we are going to create this assembly animation without the use of any solvers.

Custom Particle Movement

• After we set up the geometry assembly, the other layers will be created in more of the traditional way, with the help of solvers.For the particle streams, we’re going to base the movement on the curves that we created for our assembly.Here we will use an advanced setup in VOPs to have complete control over the motion.

Smoke & Particle Advection

• We are also going to use our fracture setup to create the smoke, and then use the smoke to advect particles, which will become the embers.

HeightField & Asset Scattering

• Aside from all of the effects, we are going to use Heightfields to create some simple mountains in the back.Then we will use megascans to add more rocks and variety to our scene, to make it feel more realistic.

Lighting, Rendering & AOVs

• In the rendering sections we will set up all of the lights and materials, and render everything using Redshift.Here we will also discuss best practices and how to set up different light passes and AOVs.

Compositing

• In nuke we will bring all of our renders and start putting everything together.We will separate the AOVs for each layer so we can have complete control over the final output.

Relighting

• We will use the Bump Normals and World Position AOVs to relight our shot and extra rim detail on the subject.

Fog Particles

• We’re also going to use Nuke’s particle system to create an additional fog layer to create a more interesting look.

我们将通过使用voronoi和布尔技术压裂我们的手几何开始本课程。

程序SOP设置

在我们创建了破碎的部件之后，我们将在SOP级别完全设置组装动画。作品的运动将由曲线决定，我们可以直接艺术和实时改变，而无需重新模拟任何东西。所以我们将在不使用任何求解器的情况下创建这个装配动画。

自定义粒子运动

在我们设置几何组件之后，其他层将以更传统的方式创建
