The Gnomon Workshop – Practical Lighting for Production

探索使用行业标准软件 Maya、Arnold 和 Nuke，完成镜头灯光和合成，使其与电影参考素材完全匹配的完整流程。本次中级工作坊由 Graham Cunningham 主讲，专为对全 CG 灯光工作流程感兴趣的人士设计。

艺术家们将学习如何在 Maya 中搭建基础的视觉开发灯光装置，从 3D Scan Store 导入角色，分配材质，讨论着色组件，并创建旋转台设置。之后，Graham 将指导如何创建镜头摄像机，并使用 KitBash3D 中的资源布置场景。课程还将涵盖角色照明策略，包括如何使用穹顶灯和区域光进行主光、填充光、边缘光等照明。此外，课程还会讲解如何使用 HDRI 贴图，Graham 将解释如何使用 Nuke 对其进行修改。

接下来，工作坊深入讲解了如何使用 Arnold 进行渲染，包括渲染设置、景深以及如何创建渲染通道。随后，Graham 转战 Nuke，组装渲染通道，分离出灯光 AOV，并演示如何调整灯光颜色和强度。他还详细讲解了如何添加氛围、如何使用加密遮罩微调效果、如何添加后期特效，以及最后如何应用最终调色以匹配他选择的电影参考。

在整个研讨会期间，Graham 将分享实用的见解和行业工作流程策略，帮助您在生产环境中顺利通过镜头审核。他的测试对象 Maya 文件将作为项目文件随本次研讨会提供。

本次工作坊使用了来自 3DScanStore 的女性探险家角色、来自 KitBash3D 的残骸工具包，以及来自 KitBash3D 的货物的素材。

Title: The Gnomon Workshop – Practical Lighting for Production

Info:

Explore the complete process of lighting and compositing a shot to match a movie reference, using industry-standard software, Maya, Arnold, and Nuke. This intermediate-level workshop, led by Graham Cunningham, is designed for anyone interested in full-CG lighting workflows.

Artists will learn how to set up a basic look development light rig in Maya, import a character from 3D Scan Store, assign materials, discuss shading components, and create a turntable setup. From there, Graham instructs how to make a shot camera and set dress the environment with assets from KitBash3D. Strategies for lighting a character are also covered, including how to use dome lights and area lights for Key, Fill, Rim, and so on. HDRI maps are also utilized, and Graham explains how to modify them using Nuke.

From there, the workshop dives into the rendering using Arnold, discussing render settings, depth of field, and how to create render passes. Then jumping into Nuke, Graham assembles the render passes, splits out the light AOVs, and shows how to adjust light colors and intensities. He also details how to add atmosphere, how to use cryptomattes to fine-tune the results, how to add post effects, and lastly, how to apply a final color grade to match his chosen movie reference.

Throughout the workshop, Graham shares practical insights and industry workflow strategies to help you get your shots approved in a production environment. His Test Objects Maya file is provided as a project file with this workshop.

This workshop utilizes the Female Explorer Character from 3DScanStore, the Wreckage Kit from KitBash3D, as well as assets from KitBash3D’s Cargo.
