Accessory Specifications
The accessory symbol should be a 2D/3D hybrid object. At a minimum, the symbol must contain a 2D representation. Keep the accessory representation as simple as possible to reduce rendering time.
The Object Info palette for accessories and lighting instruments looks identical, but the Device Type differs (Light, Accessory, or Static Accessory).
Accessories should have a record attached for storing the default accessory values. The record should not contain fields that vary from instance to instance of an accessory. For example, do not add a Color Scroller channel field value unless that channel is used by all the color scrollers in the file.
The attached record should consist of the following fields:
 
Generic accessory category; in some cases, this can be similar, or identical to the instrument type (example accessory types include Top Hat, Barn Door, Color Scroller, Gobo Rotator, and Color Frame)
Add fields as desired; these fields are read into the Lighting Device object if the field name in the accessory record matches the field name of the Lighting Device object
