About this project
What does Fogtools add?
FogTools
**FogTools** lets you create custom fog and skies with colors, gradients, animated colors and auroras. You can use commands or a visual editor that updates live.
The mod is **100% client-side**: install it on your client and it works in singleplayer and on any server. To send fogs to other players (@a, specific players, server-wide biome fogs), use the [FogTools Plugin]
![Fogtools GUI]
What's new in 1.5
- **Visual editor (GUI)** with a color wheel, a live preview and a keybind (**G** by default)
- **Gradients with any number of colors**, each placed where you want on the color bar
- **Custom rotation**: tilt the gradient to any angle (for example 45 degrees for a diagonal sky)
- **Animated colors**: any color point can loop through several colors, each with its own timing
- **Translucent color
NONE**: leaves gaps in the fog so the original sky shows through - **Auroras**: animated curtains in the sky, with custom colors, height, intensity and speed
- **Smooth transitions** between fogs, biome fogs and auroras, even when a fade is interrupted
- **Copy and paste** fogs as text with
/fogtools copyand/fogtools paste(works from the clipboard) - **Fixed client biome fog commands**
- **Smoother color rendering**: less banding and no pixelated gradients
- Chat messages only show in **creative mode** (errors are always shown)
- New version: **26.2**
![Auroras]
Supported versions
1.20.1 - 1.20.4 - 1.21.1 - 1.21.4 - 1.21.5 - 1.21.8 - 1.21.11 - 26.2 (Fabric)
Visual editor
Press **G** (can be changed in *Controls > FogTools*) or run /fogtools editor.
- Change **radius, density, opacity, sky, rotation, fade in and fade out** with sliders
- **Color bar**: left click to add a color, drag to move it, right click to remove it
- **Color wheel** with brightness, alpha, a HEX field and a
NONE(translucent) option - **Copy the HEX** of the selected color with Ctrl+C or right click
- **Animated colors**: select a color point and press
+to add colors it will loop through, each with its own time in ticks - **Live preview**: the world behind the editor shows your fog in real time
- The editor builds the
/fogtools pastecommand for you. Click it to copy it. - Buttons: **Apply, Copy, Paste, Save to biome, Reset, Close**. Closing without applying brings back your previous fog.
- Arrow keys adjust the last slider you used (hold Shift for x10)
Commands
All commands are client-side. Fade times are in ticks (20 ticks = 1 second).
Fog
| Command | Description |
|---|---|
/fogtools set <radius> <density> <color> <sky> <opacity> <fadeIn> <fadeOut> |
Single-color fog |
/fogtools gradient set <rotation> <radius> <density> <top> <center> <bottom> <sky> <opacity> <fadeIn> <fadeOut> |
3-color gradient fog |
/fogtools paste [fog] |
Applies a fog from text. Without text, it reads your clipboard. |
/fogtools copy |
Copies the current fog to your clipboard |
/fogtools clear |

Applies an aurora from text or from the clipboard |
/fogtools aurora copy |
Copies the current aurora |
/fogtools aurora clear |
Removes the aurora |
colors: joined with+and no spaces, for exampleGREEN+AQUA+PURPLE(up to 8 colors)height: 0 to 80 (how high in the sky the aurora starts)intensity: 0 to 1speed: 0 to 10

| Command | Description |
|---|---|
/fogtools biome set <biome> <radius> <density> <color> <sky> <opacity> <fadeIn> <fadeOut> |
Single-color fog for a biome |
/fogtools biome gradient <biome> <rotation> <radius> <density> <top> <center> <bottom> <sky> <opacity> <fadeIn> <fadeOut> |

Arguments
| Argument | Values |
|---|---|
radius |
How far the fog starts |
density |
0 to 1 |
color |
A color name (RED, GOLD, AQUA...), a HEX like FF5500, a HEX with alpha like 80FF5500, or NONE |
sky |
true to also color the sky, false for the fog only |
opacity |
0 to 1 |
rotation |
radial, lineal or custom<degrees> (for example custom45) |
**Rotation:**
radial: the gradient goes from top to bottomlineal: the gradient goes from left to rightcustom: tilts the gradient.0is the same as radial,45is diagonal,90is side to side and180is upside down.
Paste format
Fogs can be shared as a single line of text. The editor and /fogtools copy create it for you.
{(radius:200,density:0.8,rotation:custom[45],colors:[RED@0,PURPLE:40>CYAN:40@0.5,NONE@1],sky:false,opacity:1,fadein:40,fadeout:40)}
colors: a list ofCOLOR@position, with the position from0to1. Without positions, the colors are spread evenly:[RED,WHITE,BLUE].- **Animated color:**
PURPLE:40>CYAN:40@0.5loops from purple to cyan and back, 40 ticks per step. - Minecraft chat only allows 256 characters. For long fogs, copy the text and run
/fogtools paste**without arguments** to paste it from your clipboard.
