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

第1課：攝影測量

本課程讓我們有機會使用我們的無人機鏡頭完成RealityCapture中的工作流程，從Nuke中的圖像序列準備到Maya Arnold和Clarisse的渲染。在現實捕捉中，我們將生成3D網格，正確對齊和定向網格，了解邊界框概念，創建一些UV和UDIM，并導出OBJ和TIF紋理。最后，我們將跳入 Maya 并重新連接所有內容，以便在 Arnold 中獲取最終布局資源。

第 2 類：Clarisse布局

我們從RealityCapture獲得了生成的3D網格，紋理和相機，是時候在Clarisse中設置所有內容了。我們將在Maya中準備3D資產，并將所有內容導出為Alembic文件。在本課程中，我們將在 Clarisse 中探索散射工具，以及 Clarisse 如何快速高效地生成我們的布局，包括船只、帳篷、塔樓。

第 3 類：查看Clarisse的發展

在此類中，我們將為每個資產做一個 lookDev。探索標準著色器并將我們的 TIF 紋理文件轉換為 TX 文件以提高內存效率。如果不進行紋理優化，RAM 可能會很快過載。我們將通過材質編輯器并連接所有貼圖，以獲得每個資產的外觀開發。

第 4 類：Clarisse照明

在直接跳轉到 Clarisse 中的照明工具之前，我們花幾分鐘時間分析板并了解照明。使用環境和定向光源設置 lightRig，并解釋不同參數如何與板匹配并集成 CG 資產。

第 5 類：Clarisse渲染

灰色、美感和陰影/反射的創建通過和渲染。探索著色層和組在 Clarisse 中的工作方式，以及在瀏覽器中保持 Clarisse 場景緊密的重要性。我們在Nuke中所有渲染的CG拍打組合，并為下一個部門獲得可靠的版本。

第6類：匹配移動第1部分

這個由三部分組成的部分由環境通才TD Michal Skowrow（Dneg London）教授，將引導您完成基于DJI Mavic 2 Pro無人機鏡頭重新創建虛擬攝像機的過程。涵蓋了整個匹配移動管道，從概述和收集必要的數據開始，去噪板，重建無人機鏡頭，匹配移動攝像機，使用三級攝影測量來排列攝像機，創建失真板，以及如何在Maya到Nuke工作流程中使用它。

第7類：匹配移動第2部分

涵蓋匹配移動過程的三個類中的第二個。Michal Skowron曾在Framestore，MPC和Dneg工作，并擔任大學講師。他為電影和電視、產品、汽車和醫療可視化領域的大型和小型制作做出了貢獻。項目包括重力，迪斯尼叢林書，火星救援以及最近的黑鏡和切爾諾貝利電視連續劇。

第8類：匹配移動第3部分

涵蓋匹配移動過程的三個類中的第三個。

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.
