力场可以困住角色并阻止他们前进。但大多数情况下，它们是虚拟屏障，由 Steve Wright 等视觉特效合成大师创建。在这个基于项目的课程中，Steve 展示了如何使用 NUKE 构建一个令人惊叹的科幻力场。他展示了如何通过为门设置动画来为基本的哑光绘画添加生命，然后键入绿屏镜头并小心地将主角（一名装甲太空战士）合成回场景中。然后，使用 NUKE 的噪声节点，Steve 创建力场动画并将其相乘以获得最大效果。最后，为了真正卖掉这个场景，他添加了交互式照明、运动模糊和其他收尾工作。收听以了解如何在您自己的项目中重新创建这种效果。

Force fields can trap characters and stop them in their tracks. But most of the time they’re virtual barriers, created by VFX compositing gurus like Steve Wright. In this project-based course, Steve shows how to build a show-stopping sci-fi force field using NUKE. He shows how to add life to a basic matte painting by animating the doors, and then keys the green-screen footage and carefully composites the main character, an armored space fighter, back into the scene. Then, using NUKE’s Noise node, Steve creates the force field animation and multiplies it for maximum effect. Finally, to really sell the scene, he adds interactive lighting, motion blur, and other finishing touches. Tune in to learn how to recreate this effect in your own projects.
Topics include:
* Pulling the key
* Making garbage mattes
* Compositing the character in the scene
* Creating the force field effect
* Setting the timing
* Creating and positioning emitters
* Adding interactive lighting
* Refining the final look
