Control Helper
The Control Helper is a powerful rigging tool that offers users a range of options to customize helper objects. Designed especially for rigging, it provides users with a variety of helper objects that can be tailored to their needs. It also includes a selector feature, which enables users to use other object's faces for selection, making rigging more intuitive and efficient.
One of the key features of the Control Helper is the variety of display types it offers. The tool includes a long list of options, such as Cross, Circle, Box, Arrow, Star, and more. Each display type has unique properties that can be adjusted using the parameters available in the Control Helper. This makes it easy for users to create custom helper objects that fit their specific rigging needs.
From simple shapes like circles and rectangles to more complex designs like cones and gears, the Control Helper provides users with a diverse range of display types to choose from. Some display types, such as the Eye, Lips, Hand, Foot, and Shoe, are even specifically designed to work with character rigs. With options such as Arrows, Pyramids, and Triangles, users can create helpers that indicate the direction or orientation of an object. Overall, the Control Helper's wide variety of display types is an important feature that allows users to create customized helper objects that meet their unique rigging needs.
