Occlusion Detection
Occlusion detection reveals where objects, trusses, people, or other projectors block the light path between a projector and its target surface — before you discover the problem during setup.
Check for blocked projection
- Add the relevant venue objects and obstacles to the scene.
- Open Analysis and choose Projector Coverage.
- Select Run Analysis.
- Use the overlay legend to find non-projected areas and check the total screen coverage.
Projector Coverage includes visible obstacles when it checks which parts of the screen each projector can reach. If coverage is missing where a projector should be visible, inspect the throw path for a blocking object.
Common occlusion sources
- Trusses — rigging bars passing in front of the throw path
- Other projectors — projectors mounted in front of each other in a linear array
- Scene objects — columns, walls, stage props or obstacles added to model the venue
- LED walls — opaque panels that block throw from projectors behind them
Fixing occlusion
After identifying an occluded area you can:
- Adjust the projector's position or angle to clear the obstacle
- Reposition the blocking object
- Add another projector to cover the blocked zone
- Document the occlusion in the PDF report as a known constraint
