Dithered distance fade for camera occluders

Fade an opaque mesh without transparency sorting: pixels are discarded against a 4 x 4 Bayer threshold pattern as the object comes close to the camera or as a fade uniform drops, so walls and props in front of the camera become see-through.

How it works

Shader type
spatial
Parameters
albedo (vec4 = 0.55, 0.6, 0.68, 1), roughness (float = 0.7), fade (float = 1), near_distance (float = 1), far_distance (float = 2.6), dither_scale (float = 1), use_distance (bool = yes)
Result
Pillars near the camera break into a regular dot pattern you can see through, solid further away.
Renderers
compatibility: compiled and rendered, forward plus: not verified, mobile: not verified

Limits to consider

The pattern is visible as a grid at low resolutions and flickers with temporal anti-aliasing off; with TAA or FSR it smooths out. Shadows use the shadow camera's distance, not the main camera's, so a faded object can still cast a full shadow.
