在本教学中，我们将学习为动画生物添加肌肉的基本工作流程，并且将它们作为皮肤变形器来使用。这种工作流程并不需要任何的动态模拟。我们先从使用Houdini的肌肉工具架工具创建简单的肌肉造型开始。我们会来学习如何调整它的造型与位置，将它们附着到你的角色骨骼上，还有如何启用自动次级动画。最后我们会来看看如何使用工具架工具来轻松设置肌肉，将它作为皮肤变形器来平衡HOUDINI的置换操作器。

In this overview video, we step through the basic workflow of adding muscles to an animated creature and applying them as a skin deformer. This particular workflow does not require any dynamics simulation. We start by creating simple muscle forms using Houdini’s Muscle Tool Shelf. We’ll learn how to adjust shape and placement, attach them to your character rig, and how to enable automatic secondary animation (jiggle). Finally, we’ll look at how the shelf tools easily set up your muscles as a skin deformer leveraging Houdini’s Muscle Displace operator.

Muscles in Houdini are versatile, easy to use, interconnected tools. Houdini’s muscle system has been designed to serve both FEM (dynamics simulations) and non-FEM (skin deformer) workflows while using a unified set of digital assets. With the foundational information presented in this video, you’ll be ready to rig up a creature with simple muscles and you’ll be prepared to take the next steps: creating custom muscles, and using muscles in simulations with Houdini’s Tissue System.

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.
