The Gnomon Workshop – Photogrammetry For Production Artists

借助这份适用于 Modo、Marmoset、Photoshop、Agisoft、Lightroom 和 ZBrush 的综合指南，使用摄影测量捕获并创建您自己的 3D 道具以进行制作。在这个时长 4 小时的研讨会中，Remedy Entertainment 的首席美术师 John William Crossland 为那些希望开始小规模摄影测量的人们阐明了整个过程。他详细介绍了实现低、中和高范围扫描的几种方法，并解释了如何生成可用作生产资产基线的高质量扫描。

John 使用他久经考验的制作工作流程逐步完成了创建登山鞋资产的整个过程，从最初的捕获到拓扑清理、硬表面建模和应用材质，再到处理最终渲染。在整个演示过程中，他展示了处理扫描数据的各种技术，以及如何创建干净的高多边形雕塑，以及准备在狨猴中进行纹理化的带有 UV 的低多边形网格。

该摄影测量研讨会旨在帮助那些经验有限的人成功制作出令人自豪的扫描结果。他的摄影测量实用指南详细介绍了处理扫描数据所需的所有步骤，并将其一直进行到最终的雕刻，包括烘焙和材料。完成本次研讨会后，您将获得有关摄影测量过程的许多实用见解，并将为以最少的设置需求开始您自己的项目提供坚实的指导。

该工作坊旨在让您与约翰一起雕刻。他的 ZBrush ZTL 文件包含所有工作步骤，以及他的 Modo 文件（以 .obj 提供的场景）和最终的 Photoshop 合成。本研讨会还包含狨猴场景文件，供订阅者访问和使用。

Title: The Gnomon Workshop – Photogrammetry For Production Artists

Info:
Capture and create your own 3D props for production using photogrammetry with this comprehensive guide for Modo, Marmoset, Photoshop, Agisoft, Lightroom, and ZBrush. In this 4-hour workshop, John William Crossland, a Lead Principal Artist at Remedy Entertainment, sheds a light on the entire process for those looking to get started with photogrammetry on a small scale. He details several ways to achieve low, medium, and high-range scans and explains how to produce a decent-quality scan that can be used as a baseline for a production asset.

John walks through the entire process of creating a mountain boot asset using his tried-and-tested production workflow, from initial capture through topology clean-up, hard-surface modeling, and applying materials, before tackling the final renders. Throughout the demonstration, he shows various techniques to process scan data and how to create a clean, high-poly sculpt, as well as a low-poly mesh with UVs ready for texturing in Marmoset.

This photogrammetry workshop is designed to help those with limited experience to successfully produce a scan to be proud of. His pragmatic guide to photogrammetry goes through all the steps needed to process your scan data and take it all the way through to a final sculpt, including baking and materials. Upon completing this workshop, you’ll have gained many practical insights into the photogrammetry process and will have a solid guideline for starting your own projects with minimal setup needs.

The workshop is intended for you to sculpt along with John. His ZBrush ZTL file is provided with all the working steps, along with his Modo file (scene supplied with .obj) and the final Photoshop composite. The Marmoset scene file is also included with this workshop for subscribers to access and utilize.
