本教程是由Allanmckay机构出品的高楼爆炸好莱坞级特效制作视频教程，时长：超过15小时，大小：30 GB，格式：MP4高清视频格式，附源文件，教程使用软件：Nuke，3dsmax，共34个章节，语言：英语。
FXPHD教程组织刚刚发布了另一个新课程，电影《奔跑》的视觉特效，参与展示的是MELS工作室。 他们在Nuke中如何使用各种技术，以及他们如何做各种人群复制的体育场射击， 所有这一切都会与电影的实际镜头做对比。本课程老师是HugoLéveillé教授，他目前是蒙特利尔Mels工作室的合成主管， 凭借超过10年的VFX经验，他将通过为Nuke创建和集成管道工具来分享他的工作时间。
当今大型电影绝伦的特效，不禁让人要惊叹其合成的逼真与强大！NUKE曾被用在Digital Domain所制作的很多电影和商业片中。NUKE 是由The Foundry公司研发的一数码节点式合成软件。已经过10年的历练，曾获得学院奖（Academy Award）。为艺术家们提供了创造具有高质素的相片效果的图像的方法。NUKE无需专门的硬件平台，但却能为艺术家提供组合和操作扫描的照片，视频板以及计算机生成的图像的灵活、有效、节约和全功能的工具。在数码领域，NUKE已被用于近百部影片和数以百计的商业和音乐电视，NUKE具有先进的将最终视觉效果与电影电视的其余部分无缝结合的能力，无论所需应用的视觉效果是什么风格或者有多复杂。Nuke合成软件参与制作的著名影视有：《后天》、《机械公敌》、《极限特工》、《泰坦尼克号》、《阿波罗13》、《真实的谎言》、《X战警》、《金刚》等。
ALLAN MCKAY LIVE ACTION SERIES TERM 1
FX Term 1 Century City Building Destruction
Before we dive into sequences of shots – where our focus will be in working on many FX for many shots and learning through the unique challenges that arise. Our goal of the first term is to jump in the deep end on a solo shot or a ‘one off’. This will give us the chance to focus all of our attention and energy on the process and walking through a real film studio pipeline.
Initially walking through the pre-production phase we’re able to learn many critical lessons on how to approach a visual effects shot ‘the right way’. Planning and discussing what’s involved and communicating our plan before we take action. From initial ‘hand over’ of our shot and then beginning to block out our shot in phases before we get involved too heavily in creating all of the elements.
As we dive into creating the effects, we first initially create our destruction and lock the look. Learning to create a solid workflow for creating our destruction dynamics and integrating it into our shot with basic lighting and shading. Our first review is after we initially build our first pass of the destruction – we then review this and decide on what areas need revisions – A really critical moment is where we then review our shot and begin to problem solve issues and revise any issues with our simulation before we finalize the animation, and export Alembic caches of everything for use in final rendering.
Once our dynamic simulation is approved and ‘published’ we move onto creating all of our effects which are driven from the base simulation we built. Initially focusing on geometry simulations we create many additional effects elements from sparks and embers, to additional secondary glass impacts, debris as well as dense clouds of dirt spilling out of the building as areas collapse. Each of these elements is also published and baked out to Alembic caches so they are final, and also require no further calculations.
After which we create many of our atmospheric effects, from various levels of dust, fire, explosions, shooters, smoke, smoke columns, flame bursts and internal large scale fire inside of the building, and dozens of other layers.
Meanwhile we have many intermediate implementations of our elements into composite inside of Nuke, which allow for us to see our shot progress and understand how it will all be integrated together. Finally once all of our elements are built, we begin to balance our renders out, focusing on the lighting and shading and adjusting layers until we have a perfect balance of all of our effects elements. We’re then able to begin to build up our scene states for render pass creation and take our final render passes into comp.
Not only do we focus on heavy treatment in comp of our elements, as well as many tricks to integrate our elements seamlessly into the shot, and adding additional reflections and many other steps. But we’re able to review our shot as a whole and what additional elements we wish to create. Here is where we’re able to go into 3D one final time to make any final adjustments, as well as to create ‘contact maps’ of any debris hitting the sides of the buildings, as well as burn maps for our pyro elements to burn and mark up the building areas around it, and interactive lighting passes to get our fire to illuminate and light our shot as well.
All of this is performed over a fairly lengthy time, our first time is one where we focus on doing a majority of heavy duty work, but our focus is on making one visual effects shot completely amazing and taking it through to final. Understanding every step of the way and learning many of the steps involved in revising our effects as we move through the process. The final look is that of a high quality Hollywood production level visual effects shot. Which now we can start to replicate this process but on a much larger scale in many more shots in the further terms. This is an intense lesson and paves the way for the rest of the course.
This is just a short excerpt from the full course description.
