Hexagon shield with travelling pulses

Energy shield made of hexagonal cells: glowing cell borders, cells that light up as a pulse wave climbs the object, random flickering cells and a Fresnel rim, drawn additively.

How it works

Shader type
spatial
Render modes
unshaded, blend_add, cull_disabled, depth_draw_never, shadows_disabled
Parameters
edge_color (vec4 = 0.3, 0.8, 1, 1), fill_color (vec4 = 0.1, 0.35, 0.8, 1), hex_scale (float = 14), edge_width (float = 0.06), pulse_speed (float = 0.6), pulse_spacing (float = 1.2), flicker_rate (float = 3), flicker_share (float = 0.1) and 1 more
Use it on
A mesh with UVs; on a sphere the cells shrink toward the poles.
Result
A glowing hexagon-tiled bubble with bands of cells lighting up as pulses climb it.

Limits to consider

Cells follow the mesh UVs, so they distort where UVs are stretched (sphere poles, seams). Additive blending cannot darken.
