3d扫描集成技术–Maya、Mari、V-Ray和Nuke工作流程

Adrian Vallecilla的5小时研讨会详细介绍了将hero资源集成到具有照片级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扫描转换为生产就绪资产，讨论了重要的硬表面建模理论，同时演示了该过程。纹理部分包括如何清理3D扫描的纹理，并使用Mari将它们投影到干净的3D资产上，这是一种标准做法，可确保CG资产在VFX制作中可用。

在Maya中，外观开发、照明和渲染是由V-Ray处理的。Adrien讨论了将板的照明与集成的3D资产相匹配以获得真实效果的重要性，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过程。除了详细描述过程，他还讨论了使用Nuke创建真实的CG集成时需要注意的问题。The Gnomon Workshop – 3d Scan Integration Techniques – Maya, Mari, V-Ray & Nuke Workflow with Adrien Vallecilla

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.
