How it works

Shader type
canvas_item
Parameters
shine_color (vec4 = 1, 1, 0.95, 1), angle_degrees (float = 30), band_width (float = 0.14), softness (float = 0.5), intensity (float = 0.9), sweep_time (float = 0.8), pause_time (float = 1.4), progress_override (float = -1)
Use it on
A Sprite2D (or other textured CanvasItem) with transparent space around its shape, assigned to the node as usual.
Result
The sprite with a bright diagonal band of light across its middle.

Limits to consider

The band moves in UV space, so in an atlas it sweeps across the whole atlas region. It brightens additively and can clip on light sprites.
