3d Scan Integration Techniques – Maya, Mari, V-Ray & Nuke Workflow with Adrien Vallecilla

Adrian Vallecilla 的 5 小时研讨会详细介绍了将英雄资产集成到具有逼真效果的背板的完整工作流程。Adrien 使用视觉效果制作中的经典技术，揭示了如何使用 Maya 将火车的 3D 扫描转换为可用于生产的资产，并在演示过程的同时讨论了重要的硬表面建模理论。纹理部分包括如何从 3D 扫描中清理纹理并使用 Mari 将它们投影回干净的 3D 资产上——这是一种确保 CG 资产可用于 VFX 制作的标准做法。

回到 Maya，外观开发、照明和渲染都是由 V-Ray 处理的。Adrien 讨论了将印版的照明与集成的 3D 资产相匹配以获得真正逼真的结果的重要性，并演示了如何重新创建正确的照明场景。使用 Maya 的渲染设置工具，Adrien 展示了如何在 Nuke 中导出专业合成所需的所有必要的光照通道。除了详细介绍流程外，他还讨论了使用 Nuke 创建逼真的 CG 集成时要注意的事项。

本次研讨会提供了 Adrien 的低分辨率环境模型和用于拍摄的相机（Maya 的 .mb 文件），您可以下载并使用您自己的资产。由 HDRI Haven 提供的 HDR 图像和背板也包含在他们的免费收藏中。

Title: The Gnomon Workshop – 3d Scan Integration Techniques – Maya, Mari, V-Ray & Nuke Workflow with Adrien Vallecilla

Info:
Adrian Vallecilla’s 5-hour workshop details a complete workflow for integrating hero assets into backplates with photorealistic results. Using a classic technique in visual effects production, Adrien reveals how to transform a 3D scan of a train into a production-ready asset using Maya, discussing the important hard-surface modeling theories while demonstrating the process. The texturing portion includes how to clean up textures from the 3D scan and project them back onto a clean 3D asset using Mari — a standard practice that ensures the CG asset is usable in VFX production.

Back in Maya, the look-dev, lighting, and rendering is handled with V-Ray. Adrien discusses the importance of matching the lighting of the plate with the 3D asset being integrated for truly realistic results and demonstrates how to recreate the correct lighting scenario. Using Maya’s render setup tools, Adrien shows how to export all the necessary lighting passes required for professional compositing in Nuke. As well as detailing the process, he also discusses what to look out for when creating realistic CG integrations using Nuke.

Provided with this workshop is Adrien’s low-res model of the environment and camera (.mb file for Maya) used for the shot, which you can download and use with your own assets. An HDR image and backplate courtesy of HDRI Haven is also included from their free collection.
