Fogtools

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 and auroras), use the [FogTools Plugin]https://www.curseforge.com/minecraft/bukkit-plugins/fogtools-pluginon your Paper server.

What's new in 1.5.1

• **Biome auroras**: give any biome its own aurora. It appears when you enter the biome and fades out when you leave.
• A biome can now have **a fog, an aurora or both**
• **Forge support**: 1.20.1, 1.20.4
• **NeoForge support**: 1.20.1, 1.20.4, 1.21.1, 1.21.4, 1.21.5, 1.21.8, 1.21.11, 26.2
• **Better editor performance**: fixed the FPS drop while the editor is open (1.21.8, 1.21.11 and 26.2)

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
• **Copy and paste** fogs as text with /fogtools copy and /fogtools paste
• **Fixed client biome fog commands**
• **Smoother color rendering**: no pixelated gradients
• Chat messages only show in **creative mode** (errors are always shown)

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
• **Live preview**: the world behind the editor shows your fog in real time
• The editor builds the /fogtools paste command 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

• /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: removes your custom fog with a smooth fade
• /fogtools editor: opens the visual editor

Auroras

• /fogtools aurora set <colors> [height] [intensity] [speed] [fadeIn] [fadeOut]: creates an aurora. Everything after the colors is optional.
• /fogtools aurora paste [aurora]: applies an aurora from text or from the clipboard
• /fogtools aurora copy: copies the current aurora
• /fogtools aurora clear: removes the aurora

Aurora values:

• **colors**: joined with + and no spaces, for example GREEN+AQUA+PURPLE (up to 8 colors)
• **height**: 0 to 80 (how high in the sky the aurora starts)
• **intensity**: 0 to 1
• **speed**: 0 to 10

Auroras are easiest to see at night.

Biome fogs and auroras

• /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>: gradient fog for a biome
• /fogtools biome paste <biome> [fog]: pasted fog for a biome
• /fogtools biome clear <biome>: removes a biome's fog
• /fogtools biome aurora set <biome> <colors> [height] [intensity] [speed] [fadeIn] [fadeOut]: aurora for a biome
• /fogtools biome aurora paste <biome> [aurora]: pasted aurora for a biome
• /fogtools biome aurora clear <biome>: removes a biome's aurora
• /fogtools biome list: lists every biome with a fog or an aurora
• /fogtools biome current: shows the biome you are standing in

Biome fogs and auroras are saved in config/fogtools-biome-fogs.json and fade in and out as you walk between biomes. A biome can have a fog, an aurora or both.

**Priority:**

• Fog: editor preview > custom fog (commands or server) > biome fog. /fogtools clear goes back to the biome fog if there is one.
• Aurora: custom aurora (commands or server) > biome aurora. /fogtools aurora clear goes back to the biome aurora if there is one.

---

Arguments

• **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 bottom
• **lineal**: the gradient goes from left to right
• **custom**: tilts the gradient. 0 is the same as radial, 45 is diagonal, 90 is side to side and 180 is 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 of COLOR@position, with the position from 0 to 1. Without positions, the colors are spread evenly: [RED,WHITE,BLUE]
• **Animated color**: PURPLE:40>CYAN:40@0.5 loops 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.
