# Binders Binders determine where a vfx should be created, and its tracking behavior (should it follow a moving character). There are several types of binders: * Point (the most common, attach to a character, for example) * Camera * Spline * Linear Binders can be attached to caster or target, and have several "property" fields. Properties have the attribute `BinderPointId`, which allows a vfx to be bound to a specific point on a model (such as at the hilt of a sword). Binder points are specified in the skeleton's `.mdl` file, although this is not well-understood. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
