在本教学中你将学习到如何从零开始从MIXAMO网站下载动画角色并且将它输出到HOUDINI中用于布料仿真。教学将从登陆Mixamo网站开 始，然后输出FBX文件，接着将结果输出到HOUDINI或者是HOUDINI学习版中。你将会学习到如何正确的缩放这个角色，并且将动画缓存到几何体文 件中。

In this lesson, you will learn how to start from scratch as you set up and download an animated character from the Mixamo website then export the character in Houdini for use in a cloth simulation. You will start with free content from the Mixamo site, export it as an FBX file then import the results into either Houdini or Houdini Apprentice. You will then learn how to properly scale your character and cache out the motion into geometry files.

You will then learn how to set up a simple cloth simulation using the animated character as a collision object. You will model a skirt then attach it to the character and simulate. There will also be tips for caching out the simulation to make it more efficient for rendering. For more information on specific cloth properties, you can also take a look at the Cloth Masterclass.

There is currently a Costume Contest being held where you can create a character, animate it using Mixamo motion and add a cloth sim in Houdini. Mixamo has excellent auto-rigging tools which allows you to very easily add motion to your own character.

Side Effects刚开始的时候只有两个人：Kim Davidson与Greg Hermanovic，他们是热衷于UNIX下编程的动画爱好者。1985年的时候，他们加入了创新型公司奥林巴斯，然后沉浸在创作的过程中，编写他们自己的软件，为电影与广播制作视觉特效。1987年一个偶然的机会将3D动画呈现在观众眼前之后，Davidson与Hermanovic创建了Side Effects软件，并且发布了PRISMS.它是一个程序化制作软件，为HOUDINI的奠定了基础。

Side Effects因Houdini及其创新性的流程化制作技术两次获得了奥斯卡奖，另外很多奥斯卡奖影片是使用HOUDINI制作的。奥斯卡奖的获得是对Side Effects强大的研究开发能力与它同客户之间良好的沟通关系的承认。Side Effects以在这个快速发展的行业建立了领导性的地位而自豪，并且持续不断的寻找那些能够支持创新过程的新方法。

For over twenty years Side Effects has been providing artists with procedural 3D animation and visual effects tools designed to create the highest-quality cinematic results. We are passionate about what our customers do because our roots are in production, both as artists and as pioneering technical innovators.

For over Twenty Years…

In the beginning there were two: Kim Davidson and Greg Hermanovic – animation enthusiasts with a flair for UNIX coding. In 1985 they joined Omnibus, a pioneering company in the then emerging world of computer graphics. They immersed themselves in production, writing their own software and creating visual effects for film and broadcast.

In 1987, with an opportunity to bring 3D graphics to a wider audience, Davidson and Hermanovic created Side Effects Software and released PRISMS. Developed and rigorously tested in production, PRISMS was a procedural graphics application which would lay the groundwork for Houdini.

Award-Winning Procedural Technology

Side Effects Software has twice been recognized by the Academy of Motion Pictures, Arts and Sciences for Houdini and its breakthrough procedural based technology. In addition, Academy Awards have been given to many films which relied on Houdini for the creation of their visual effects.

This recognition is an acknowledgment of Side Effects’ strong research and development team and its close interaction with customers to understand and address production needs. Side Effects takes pride in establishing a leadership role in this fast-paced industry and is constantly looking for ways to support the creative process while pushing the “innovation” envelope.

Innovation and Customer Service

At Side Effects, we value innovation, integrity and commitment to the customer. With deep roots in production, we know what it takes for CG artists to succeed. Every day we apply that knowledge and strive to help our customers achieve more with less effort.

Side Effects is also committed to the growth of skills in the industry as demonstrated by the Houdini Apprentice program that gives digital artists the chance to build skills and create demo-reel content using Houdini free of charge.

As the industry continues to evolve, we remain dedicated to working with studios and artists to meet their production challenges head-on. Our knowledgable staff, our responsive customer support, and access to daily software builds are a few of the things that set us apart and make Side Effects a great company to do business with.
