Tag any QGIS layer group as a "Transmittance Group" to open an interactive 2D control panel.
The canvas plots each layer as a draggable dot — X axis controls stacking order, Y axis controls opacity. Drag a dot to adjust both at once. Click a dot to toggle its visibility.
Key features:
- Real-time opacity and order editing with immediate map feedback
- Label control: a △ indicator selects which layer displays its QGIS label
- Exclusive Control mode: click any dot to show only that layer and its label; cycle through layers with arrow keys
- Opacity clamping: define an upper/lower opacity range applied across all layers
- Presets (×4): save and restore full panel states, including order, opacity, clamping, and exclusive control settings
Designed for workflows that involve comparing multiple overlapping layers — such as elevation models, orthophotos, and feature layers — where visual blending and quick layer switching matter.
