Param Groups (LACS)
All fixture parameters are organized into four groups, providing consistent navigation regardless of fixture type.
The Four Groups
| Group | Parameters |
|---|---|
| Level | Dimmer, level, intensity |
| Aim | Pan, tilt, position, beam position, zoom |
| Hue | ColorAdd R/G/B, hue, color, white |
| Shape | Beam, gobo, effect, shutter, strobe, focus, iris |
Benefits
- Consistent workflow — The Controls (programmer) window is organized by these groups: Dimmer, Color, Gobo, and Position tabs
- Cleaner value sets — The Value Sets window carries one tab per group (Level, Aim, Hue, Shape)
- Better organization — Programmer controls and value sets are both organized by group
How It Works
When a fixture definition is imported from a GDTF file, PRISM maps its attributes to the LACS groups. A moving head’s pan and tilt land under Aim; an RGB LED bar’s R, G, B channels land under Hue. Attribute types without a mapping get no group. The group is the same; the underlying channels differ.
