Qualoth 和FXHair是提供给Maya来模拟运算衣物和头发特效的软体，由韩国公司FXGear所研发出来。

Qualoth号称其运算效果比知名的Maya衣物模拟外挂Syflex还要来的更强大，其软体也已广泛运用在如Shrek(台译：史瑞克)、Lineage(台译：天堂)等知名影片制作中。

FXHair主要是处理Maya Hair的模拟运算部分。号称可以在与身体作碰撞、加上风力场的情况下，以每三秒一个fram的效率处理3500个Curves(75000控制点)。

从官方网站上的展示片来看，其结果是相当惊人，有兴趣的人可以去看看。

Qualoth 2012 V2 for MAYA Win/Linux

Qualoth is a production-proven cloth simulator aimed for high quality cloth animation creation. It has a sophisticated physical model and numerical algorithms that produce realistic wrinkles and animation, and reliable collision handling mechanism and rich set of controls that give users more time for creativity than trouble-shooting.

Qualoth is available for Maya 2009, 2010,2011 and 2012 in Windows and Linux.

Robust Collision Handling

Qualoth can detect and resolve collisions to fast-moving objects, and the self-collision can be resolved robustly even when the cloth is trapped between collision objects.

Multiple Layers

The reliable collision handling allows simulation of complicated multi-layered garments animation. The performance of qualoth is best shown when simulating such garments as below.

Realistic Wrinkles

The material that Qualoth simulates is not a spring network. Its physical model is based-on deep understanding of cloth material property that differs from rubbers and other elastic materials. The realistic wrinkles and motions of cloth simulated by Qualoth come from an advanced physical model and efficient numerical techniques.

Cloth Creation

Qualoth provides the panel-based garment creation method as well as 3D mesh-based creation. The panel-based creations allows multiple seams at a single curve, which enables creation of non-manifold surface such as pleats. 3D mesh-based creation provides options to imitate panel-based creation method to get more cloth-like material behavior.

Fields

Qualoth accepts all kinds of Maya dynamic fields such as air and turbulence fields.

Attribute Maps

Qualoth provides fifteen maps that can be painted per-vertex. It can be saved and loaded as a binary file or texture file.

Cache

Qualoth supports per-frame cache files and a single continuous cache file. Also, any kind of mesh animation can be baked into Qualoth cache files.

Cloth Blending

Any kind of meshes including cloth meshes driven by Qualoth can be blended using the Qualoth?셲 mesh mixer. The blending weights can be painted per-vertex and are normalized automatically.

Crease Simulation

Cloth has hysteretic behavior. Once folded, the wrinkles are not gone completely unless are ironed out. This kind of creases can be simulated by Qualoth with ‘bend plasticity’ property. Crease simulation produces natural thick creases conforming to body joint movements, and it can be fixed once satisfactory crease patterns are acquired. If plasticity is used during animation, it will reduce rubber-like look and movement and look more natural.

Goal Shape

The goal shape or rest shape can be animated and applied to simulation.

Local Space Simulation

Local space simulation is an efficient way to fast moving cloth animation. Users can control the amount of inertial effect and air-drag caused by world-space movement to local space simulation.
