This model is meant to be used for lighting visualization of stages and shows. the polycount is reduced relating to the model you can get from the manufacturer. The fixture comes in two versions: Spotlight and washlight.
The light source is modified to look like a real spotlight with output glow and a nice flare when you look into it. Even Gobos look great as beam effect.
The Fixture is driven by expresso and is controlled like you would control it by a lighting console.
controllable are: - intensity - color - pan/tilt - zoom - iris - gobo and gobo rotation
- several render options
The Gobo section is pretty handy. you can create custom gobo materials and just drag and drop them in the gobo link.
You safe a lot of time with it and your renders will be looking great.
