Soft particle card with depth fade

Transparent card material for smoke, dust and glow sprites that removes the hard line where the card cuts into geometry: alpha fades by the distance to the scene depth behind it, and near the camera.

How it works

Shader type
spatial
Render modes
unshaded, cull_disabled, depth_draw_never, shadows_disabled
Parameters
depth_texture (sampler2D), sprite (sampler2D), tint (vec4 = 0.8, 0.82, 0.88, 0.8), fade_distance (float = 0.6), camera_fade_near (float = 0.3), camera_fade_far (float = 0.8), fade_power (float = 1)
Use it on
Optional: a sprite texture with alpha for `sprite` (the bundled material uses a procedural one).
Result
Soft grey puffs that blend smoothly into the floor and the crate where they intersect.
Renderers
compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
Placement

Limits to consider

Only opaque geometry is in the depth buffer; cards do not soften against each other. The gap is measured along the view axis. Unshaded: combine with `smoke_billboard` ideas for lit puffs. Cards are sorted per object.
