Drops and streaks¶
Rain on surfaces: beads on up-facing areas, running streaks on walls and glass. Both follow Weather Rain.
| Feature | Switch / key parameters | What it gives | Cost |
|---|---|---|---|
| Drops | Use Drops?, Drops Scale, Drops Size, Drops Speed | Beads that land, sit and dry on up-facing surfaces | +1 |
| Streaks | Use Streaks?, Streaks Scale, Streaks Amount, Streaks Width | Rivulets with a drop running down in steps, always straight down in world space | no textures |
| Wide streaks / droplets | Streaks Large, Streaks Droplets | Extra wide rivulets, small static droplets between them (0 = off) | - |
Drops Roughness (group Weather) sets the gloss of all drops: 0.03–0.08 = clean water.
Tips¶
- Scale = per cm: higher = smaller and denser (Streaks Scale 0.2 = one rivulet every 5 cm).
- Cheaper streaks: Streaks Layers 2 looks almost the same as 3.
- Streaks Fade Distance (cm): beyond it streaks fade out and cost nothing.
- Straight lines: lower Streaks Wiggle (0 = straight).
