FXPHD - VFX307 - Clarisse 和 Nuke 模型合成到场景的特效教程，18.3GB

第1课：摄影测量

本课程让我们有机会使用我们的无人机镜头完成RealityCapture中的工作流程，从Nuke中的图像序列准备到Maya Arnold和Clarisse的渲染。在现实捕捉中，我们将生成3D网格，正确对齐和定向网格，了解边界框概念，创建一些UV和UDIM，并导出OBJ和TIF纹理。最后，我们将跳入 Maya 并重新连接所有内容，以便在 Arnold 中获取最终布局资源。

第 2 类：Clarisse布局

我们从RealityCapture获得了生成的3D网格，纹理和相机，是时候在Clarisse中设置所有内容了。我们将在Maya中准备3D资产，并将所有内容导出为Alembic文件。在本课程中，我们将在 Clarisse 中探索散射工具，以及 Clarisse 如何快速高效地生成我们的布局，包括船只、帐篷、塔楼。

第 3 类：查看Clarisse的发展

在此类中，我们将为每个资产做一个 lookDev。探索标准着色器并将我们的 TIF 纹理文件转换为 TX 文件以提高内存效率。如果不进行纹理优化，RAM 可能会很快过载。我们将通过材质编辑器并连接所有贴图，以获得每个资产的外观开发。

第 4 类：Clarisse照明

在直接跳转到 Clarisse 中的照明工具之前，我们花几分钟时间分析板并了解照明。使用环境和定向光源设置 lightRig，并解释不同参数如何与板匹配并集成 CG 资产。

第 5 类：Clarisse渲染

灰色、美感和阴影/反射的创建通过和渲染。探索着色层和组在 Clarisse 中的工作方式，以及在浏览器中保持 Clarisse 场景紧密的重要性。我们在Nuke中所有渲染的CG拍打组合，并为下一个部门获得可靠的版本。

第6类：匹配移动第1部分

这个由三部分组成的部分由环境通才TD Michal Skowrow（Dneg London）教授，将引导您完成基于DJI Mavic 2 Pro无人机镜头重新创建虚拟摄像机的过程。涵盖了整个匹配移动管道，从概述和收集必要的数据开始，去噪板，重建无人机镜头，匹配移动摄像机，使用三级摄影测量来排列摄像机，创建失真板，以及如何在Maya到Nuke工作流程中使用它。

第7类：匹配移动第2部分

涵盖匹配移动过程的三个类中的第二个。Michal Skowron曾在Framestore，MPC和Dneg工作，并担任大学讲师。他为电影和电视、产品、汽车和医疗可视化领域的大型和小型制作做出了贡献。项目包括重力，迪斯尼丛林书，火星救援以及最近的黑镜和切尔诺贝利电视连续剧。

第8类：匹配移动第3部分

涵盖匹配移动过程的三个类中的第三个。

CLASS 1: PHOTOGRAMMETRY

This class give us the opportunity to go through the workflow in RealityCapture with our Drone footage from the preparation of the images sequence in Nuke to the render in Maya Arnold and Clarisse. In Reality-capture we will generate the 3D mesh, align and orient properly the mesh, understand the bounding box concept, create some UVs and UDIM?s and export an OBJ and TIF textures. Finally, we will jump in Maya and reconnect everything to get our final Layout asset in Arnold.

CLASS 2: LAYOUT IN CLARISSE

We got from RealityCapture our 3D mesh generated, textures and Camera, it?s time to set up everything in Clarisse. We will prepare our 3D asset in Maya and export everything as an Alembic file. In this class we will explore in Clarisse the scattering tool and how quick and efficient Clarisse can be to generate our layout with boats, tent, towers for our shot.

CLASS 3: LOOK DEVELOPMENT IN CLARISSE

In this class we will do a lookDev for each asset. Explore the Standard shader and convert our TIF texture file to TX files for memory efficiency. Without texture optimization, the RAM could quickly overload. We will go through the Material Editor and connect all our maps to get our lookDev for each asset.

CLASS 4: LIGHTING IN CLARISSE

Before jumping straight to the lighting tool in Clarisse, we spend couple of minutes analylzing the plate and understand lighting. Setup of the lightRig with Environment and Directional Lights and explain how the different parameters work to match to the plate and integrate the CG assets.

CLASS 5: RENDERING IN CLARISSE

Creation of the Grey, Beauty and Shadow/Reflection passes and renders. An exploration as to how ShadingLayer and groups work in Clarisse and how it?s important to keep the Clarisse scene tight up in the Browser. A CG slap comp of all our renders in Nuke and get a solid version for the next department.

CLASS 6: MATCHMOVE PART 1

This three part section, taught by Environments Generalist TD Michal Skowrow (Dneg London), walks you through the process of recreating a virtual camera based on the DJI Mavic 2 Pro drone footage. The entire matchmove pipeline is covered, starting with an overview and gathering of necessary data, de-noising plates, reconstruction of the drone lens, matchmoving the camera, working with the class three photogrammetry to line-up the camera, creation of distortion plate, and how to use it inMaya to Nuke workflow.

CLASS 7: MATCHMOVE PART 2

The second of three classes covering the matchmove process. Michal Skowron has worked for Framestore, MPC and Dneg and also as a university lecturer. He has contributed to larger and smaller productions both in film and TV, product, automotive and medical visualization. Projects include Gravity, Disney Jungle Book, The Martian and more recently the Black Mirror and Chernobyl TV series.

CLASS 8: MATCHMOVE PART 3

The third of three classes covering the matchmove process.
