The Gnomon Workshop - Photogrammetry for Production Artists

使用攝影測量捕獲技術并創建您自己的3D模型，使用Modo，Marmoset，Photoshop，Agisoft，Lightroom和ZBrush的進行建模的綜合教程。

在這個4小時的研討會中，Remedy Entertainment的首席藝術家John William Crossland為那些希望開始小規模攝影測量的人揭示整個過程。他詳細介紹了實現低、中、高范圍掃描的幾種方法，并解釋了如何生成可用作生產資產基線的高質量掃描。

John 使用他久經考驗的制作工作流程完成了創建山地靴子資產的整個過程，從初始捕獲到拓撲清理、硬表面建模和應用材質，然后再處理最終渲染。在整個演示過程中，他展示了處理掃描數據的各種技術，以及如何創建干凈的高多邊形雕刻，以及帶有UV的低多邊形網格，以便在狨猴中進行紋理處理。

這個攝影測量研討會旨在幫助那些經驗有限的人成功制作出值得驕傲的掃描件。他的攝影測量實用指南介紹了處理掃描數據所需的所有步驟，并將其一直帶到最終雕刻，包括烘焙和材料。完成本次研討會后，您將獲得許多關于攝影測量過程的實用見解，并將獲得以最少的設置需求啟動自己的項目的可靠指南。

該工作坊旨在讓您與約翰一起雕刻。他的ZBrush ZTL文件提供了所有的工作步驟，以及他的Modo文件（場景由.obj提供）和最終的Photoshop合成。狨猴場景文件也包括在這個研討會中，供訂閱者訪問和使用。

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.
