Checkerboard grid for LED video panels. Define cell size in pixels and cols×rows count, with half-module offset for panels that split mid-cell. Full color control for Cell A, Cell B, grid lines and info text — each with a random button and 8 quick-access color presets. Toggle IDs, logo and border. Mask mode lets you paint individual cells black to mark dead or hidden zones.

Alignment patterns for multi-projector arrays. Pick resolution from presets or enter custom, set cols×rows and edge blend % — total output size updates automatically. Dedicated blend color visualizes the overlap region. Circle overlay aids lens circle alignment. Canvas sub-mode composites projectors with per-screen X/Y offset and exports directly to Resolume Arena XML.

Square test patterns for fulldome projection. Standard mode draws a center-anchored grid with radial lines and a safe area ring. Zones mode renders concentric percentage rings from center — useful for fish-eye lens calibration and dome panel zone mapping. Brightness control for ambient-aware alignment.
