Maya Muscle is a skin deformer that allows users to rig characters with underlying muscle objects to create realistic skin deformation. Maya Muscle also lets users paint weights per-point to define exactly how the muscle attributes (Sticky, Sliding, Relax, Jiggle) affect the skin. This is a time-consuming and computation-heavy process. However, there are tools available to simplify the process, such as the Maya Techniques | Custom Character Toolkit DVD by Erick Miller and Paul Thuriot, which includes a fusiform and multi-belly muscle model.

What You'll Learn
Muscle simulations
Maya Muscle is a skin deformer that allows riggers to create realistic skin deformation by rigging characters with underlying muscle objects. Any NURBS surface in Maya can be converted to include a Muscle Object shape node, which can then be connected to the Maya Muscle skin deformer. This enables the creation of muscles based on the character's skeleton, so that when the skeleton moves, the muscle objects squash and stretch, driving the surface of the character's skin. Maya Muscle also offers features such as Displacement, Force, Jiggle, Relax, Smooth, and Collision, which can be used to create other deformation effects.
To create muscle simulations, one can start by building a skeleton and then modelling the muscles and the rest of the character's body. This can be done using basic deformers offered by Maya, such as the Sculpt Deformer, which is a sphere that pushes local points away from it and can be used to create the effect of muscles sliding and moving under the skin. Additionally, there are tools and plugins available, such as the skinShapeDeformer by Erick Miller and Paul Thuriot, which simplify the rigging process.
It is worth noting that creating muscle models and simulations can be time-consuming and computationally intensive. Animators often work with low-res proxy meshes and add muscle simulation afterward once the animation is ready. Additionally, there are collaborative efforts in the industry to create open-source muscle flexing and skinning plugins for Maya, which could provide further tools and simplify the process of creating muscle simulations.

Multi-belly muscle modelling
To achieve this, artists can utilise Maya's muscle deformation tools, such as the Sculpt Deformer, which uses a sphere to push local points away from it, creating the desired muscle shape. Additionally, Maya's skin deformer, Maya Muscle, allows for the creation of underlying muscle objects that drive the deformation of the character's skin. This tool enables artists to paint weights per point, precisely controlling how the muscle attributes, such as Sticky, Sliding, Relax, and Jiggle, affect the skin.
For multi-belly muscle modelling, artists can group several fusiform shapes to create more complex muscle structures. This technique is particularly useful for modelling muscles with multiple heads or origins/insertions, such as the biceps brachii, which is considered 'digastirc', meaning it has two bellies or heads. By giving a muscle additional heads or origins/insertions, it can generate more power, similar to having multiple muscles pulling on the same tendon.
Judd Simantov and Mark Edwards have developed a multi-belly generator for Maya, which simplifies the process by bridging two curves with multi-belly NURBS spheres and incorporating constraints and jiggle deformers. This tool can be found at cgMuscle.com, along with the associated MEL scripts. Additionally, Erick Miller and Paul Thuriot's Maya Techniques | Custom Character Toolkit DVD offers a great fusiform and multi-belly muscle model, providing valuable insights into studio pipelines and rigging for production use.

Muscle flexing and skinning plugins
Maya Muscle is a popular plugin that allows users to create realistic muscle and skin simulations. It is a skin deformer that lets you rig characters with underlying muscle objects to create realistic skin deformation. Maya Muscle also supports collision detection, which means you can create realistic interactions between muscles and other objects. This plugin is particularly useful for creating realistic characters with natural-looking movements.
The Maya Muscle guide provides detailed information on setting up your character rig to work with Maya Muscle for skin deformation and other deformation effects. Maya Muscle lets you paint weights per point to define exactly how the muscle attributes (Sticky, Sliding, Relax, Jiggle) affect the skin. You can also use Muscle’s independent Displacement, Force, Jiggle, Relax, Smooth, and Collision features to create other deformation effects.
Judd Simantov and Mark Edwards have created a multi-belly generator for Maya that bridges two curves with multi-belly NURBS spheres, set up with constraints, jiggle deformers, etc. This Maya plugin and its associated MEL scripts can be found at cgMuscle.com. Judd and Mark are also working with others in the industry to create an open-source muscle flexing and skinning plugin for Maya.
In addition to Maya Muscle, there are other plugins available for Maya that can enhance its functionality and make certain tasks easier. For example, the Redshift Renderer is a GPU-based renderer that allows for high-quality, fast rendering. The Substance Painter Live Link plugin simplifies the process of texturing and allows you to see the results in real time.

Sculpt Deformers
The Sculpt Deformer can be used to create complex musculo-skeletal deformations, especially in larger animals. This is achieved by parenting the Sculpt Tool to the skeleton of the character. The Sculpt Tool can be any NURBs object, and using a NURBs object as your Sculpt Tool is also referred to as using a custom sculpt tool.
For example, when simulating the musculature of a horse's leg, you can use multi-belly NURBs spheres to create multiple 'fusiform-like' muscles connected along the origin and insertion of a multipennate muscle. This is a technique put forth by Judd Simantov and Mark Edwards, who have created a multi-belly generator for Maya. Their tool bridges two curves with multi-belly NURBs spheres, with constraints and jiggle deformers.
The Sculpt Deformer can also be used in conjunction with other deformers, such as the Wrap Deformer, to create realistic muscle and skin motion. The Wrap Deformer allows you to deform a mesh with an internal mesh or 'muscle', and the sculpt deformer can be used to create sliding and moving muscles under the skin.

Muscle displacement, force, and jiggle
Maya Muscle is a skin deformer that allows you to rig characters with underlying muscle objects to create realistic skin deformation. It is a powerful tool for simulating musculature in Maya. Maya Muscle's independent features, including Displacement, Force, Jiggle, Relax, Smooth, and Collision, enable the creation of various deformation effects. These features can be utilised to model muscle displacement, force, and jiggle, enhancing the realism of animated characters.
Displacement in Maya Muscle refers to the ability to deform the character's skin realistically by squashing and stretching the underlying muscle objects. This is achieved by building muscles based on the character's skeleton, so when the skeleton moves, the muscle objects deform accordingly, driving the surface of the character's skin. For instance, when an animated character moves its arm, the muscles in the arm would contract and expand, causing the skin to stretch and compress in response.
The Force feature in Maya Muscle allows you to set the amount of force required to trigger specific muscle movements. This is particularly useful for creating impact motions, such as when a large creature plants its foot during a walk cycle. By adjusting the force values, you can control the strength and intensity of the muscle's response to external forces. For example, you can make the muscle jiggle more intensely when a character runs and create a more subtle jiggle when the character walks.
Jiggle in Maya Muscle refers to the secondary motion or bounce of the muscle when it undergoes a rapid change in motion, such as transitioning from stationary to moving or vice versa. The Jiggle attribute includes settings like Cycle, Rest, and Impact, which can be adjusted to fine-tune the jiggle effect. Additionally, Maya Muscle provides X, Y, and Z values to control the direction and intensity of the jiggle. The X and Z values strengthen or dampen the motion in the muscle's plane, while the Y value changes the jiggle along the muscle's length. The number of frames the muscle takes to bounce back and forth and come to rest can also be adjusted, affecting the overall appearance of the muscle's movement.
Maya Muscle also offers advanced tools and plugins to enhance muscle modelling further. For example, the skinShapeDeformer by Erick Miller and Paul Thuriot provides paintable weights and significantly faster calculations. Additionally, Judd Simantov and Mark Edwards have developed a multi-belly generator for Maya, which includes jiggle deformers and other features to simplify muscle modelling. These tools demonstrate the ongoing advancements in muscle simulation within the Maya community.
