Digital Rain — your world drawn in falling code. A free post-process material for Unreal Engine and UEFN.
Put one material into a Post Process Volume and the screen turns into streams of glowing glyphs falling down the columns. The scene shows through the code — brighter where it is lit, sharp along silhouettes — so you can still walk around in it.
WHAT IT DOES
8 ready looks: Classic Rain, Code Vision, Binary Stream, Hex Terminal, Red Alert, Color Code, Ghost Overlay, Digit Storm.
The world in code. Glyph brightness follows the scene's light, silhouettes and creases glow, near surfaces stay readable even in the dark — tuned so a level is playable in this view.
Full control of the rain: speed, speed variation, trail length, density, glyph change rate, head glow.
Character sets: katakana-like signs, digits, binary 0/1, hex — 64 glyphs drawn for this pack, mirrored or not. Swap in your own glyph atlas.
Colours: any glyph / head / background colour, or glyphs in the colours of the scene; scanlines and vignette.
Only some objects in code. Custom Stencil mask: the effect everywhere, only on marked objects, or everywhere except them.
MATERIALS ONLY
No Blueprints, no C++, no plugins. One master material built from short Material Functions — no Custom node, which is why the same pack works in UEFN.
PLEASE NOTE
The scenes, environments, characters and props shown in the images and videos are used only to demonstrate the effect and are not included in this product. The product contains the post-process materials only (master material, presets, Material Functions and their texture) and an overview map built from simple engine shapes.
REQUIREMENTS
Object mask: Project Settings > Rendering > Postprocessing > Custom Depth-Stencil Pass = Enabled with Stencil.
