Fields

active_channel: GBufferDebugChannel

Which channel is currently being displayed.

enabled: bool

Whether the debug view is enabled.

exposure: f32

Exposure multiplier for HDR channels (emission, position range).

depth_near: f32

Depth visualization near plane override (0 = auto).

depth_far: f32

Depth visualization far plane override (0 = auto).

grid_cols: u32

Grid layout dimensions when showing all channels.

grid_rows: u32

overlay_opacity: f32

Overlay opacity when compositing debug view over the scene (0..1).

material_id_palette: Vec<[f32; 3]>

False color palette for material ID visualization.

zoom: f32

Zoom level for the debug view (1.0 = fit to screen).

pan: [f32; 2]

Pan offset in normalized coordinates.

show_pixel_values: bool

Whether to show numeric values at cursor position.

cursor_pos: [u32; 2]

Cursor position for pixel value readback.
