Interface GeoDecalOptions

Altitude (m) of the projector above the footprint center — the ortho cast starts here. Must clear the tallest terrain under the footprint. Default 3000.

Approximate terrain elevation (m above the ellipsoid) at the footprint center; the projector hovers height above THIS. Default 0.

Projector far plane (m). Must reach the lowest terrain under the footprint (measured from the projector). Default height * 2.

Composite lit (paints G-buffer albedo before lighting → receives terrain light/shadow) or unlit (flat, always visible over the lit scene). Default true (lit).

Blend mode. Default 'alpha'.

Opacity in [0,1]. Default 1.
