HiWire - BetterGrass

Mod that makes grass cover the sides of blocks on hills and slopes, instead of leaving a strip of bare dirt.

Features

• Better Grass Sides - Grass blocks get full-grass sides where the terrain steps down, instead of a dirt edge on every slope
• Every Grass Type - Works on all seven grass families: normal, Lush, Dry, Cold, Sunny, Wet and Withered
• Leafy Soil Too - Leaf litter gets the same treatment, and reads as one continuous surface with grass
• Fixed Grass Blending - Corrects the transitions between grass types, which in vanilla blend both ways at once and stack two masks on the same edge
• Fixed Sunny Grass - Repairs a vanilla bug where Sunny Grass could not be tinted, leaving its blend a fixed green that clashed with grass, dirt and stone alike
• Works While You Build - Grass you place turns full when it qualifies, and the blocks around one you dig update straight away
• Automatic - No commands to run, no world pre-processing; terrain converts as players explore

Why this mod?

Hytale already ships the artwork for this. Every grass block has a _Full sibling whose sides use the grass texture instead of dirt-with-a-fringe, and worldgen places those variants by hand in a handful of zone definitions. Nothing swaps to them while you play, so a stepped hillside shows a band of dirt on every terrace instead of a continuous grass slope.

BetterGrass simply wires up what is already there.

Doing so exposed two vanilla asset bugs, which the mod also fixes:

• Grass types blend both ways at once. Every grass variant belongs to the same block group, so "blend onto other grass" and "blend onto my own kind" are the same instruction. Two neighbouring blocks each paint their edge onto the other, stacking two masks on one seam.
• Sunny Grass cannot be tinted. It is the only grass family shipping baked-colour textures with its tinting switched off, so its blend is stuck at one fixed green regardless of what it meets.

Requirements

• Hytale or Hytale Server
• Java 25

Installation

Using CurseForge App

The easiest way to install mods is via the CurseForge App, which handles installation and updates automatically.

Manual Installation

1. Download the mod JAR file
2. Place it in the mods directory:
   • Windows: %appdata%\Hytale\UserData\Mods
   • Mac: ~/Library/Application Support/Hytale/UserData/Mods
   • Linux (Flatpak): ~/.var/app/com.hypixel.HytaleLauncher/data/Hytale/UserData/Mods
   • Dedicated Server: /mods folder in your server directory
3. Restart the game or server

Since Hytale uses a server internally for both singleplayer and multiplayer, this mod works in both modes.

Only the server or world host needs the mod. Players connecting to a modded server see the improved grass without installing anything.

How It Works

A grass block switches to its full-grass variant when every exposed side has grass diagonally below it - the stepped hillside case.

Conversion happens in three places, so there is nothing to run by hand:

Existing worlds convert as players explore them. Newly generated terrain arrives already converted.

Is it safe for my world?

The mod changes real blocks rather than only their appearance, because Hytale block textures are per block type and the renderer cannot be modded. That is safe here for three reasons:

• Both variants inherit from the same parent block, so material, group, tools and drops are identical. Nothing that reacts to block type can tell them apart.
• The mod refuses to convert any pair whose halves do not drop the same items, so an asset change in a future Hytale update cannot turn the conversion into an item duplication exploit.
• The rule is one-way. A full-grass block is never converted back, because it may be one a player crafted and placed deliberately.

Commands

Examples

Check whether conversion is running:

/bettergrass enabled

Turn conversion off. Blocks already converted stay as they are:

/bettergrass enabled false

Find out why a particular block still has dirt sides:

/bettergrass explain -956 136 160

explain reports every side of the block: what is next to it, whether that hides the face, what sits diagonally below, and the verdict. It also prints to the server log.

Grass Blending

Vanilla lets grass types blend in both directions at once, so a seam between two types wears both of their edges. BetterGrass gives each family its own block group and a single blending direction, following the precedence the game already uses:

Cold > Lush > Sunny > Dry > Withered > Wet > Grass

Each type blends onto the ones below it and none above, so every boundary gets exactly one edge. Normal, Withered and Wet grass blend into each other as well, which vanilla does not do at all.

Blocks that blend onto grass from outside the family - snow, mud, leaf litter, moss, ice - keep working on every grass type.

Customization

Everything the mod changes lives in plain asset files inside the JAR, under Server/Item/Items/Soil/Grass. An asset pack of your own that overrides the same files takes precedence, so the blending order or any individual texture can be changed without rebuilding.

Building from Source

./gradlew build

The compiled mod JAR will be in mod/build/libs/.

Regenerating the asset overrides after a Hytale update:

python3 tools/generate_grass_overrides.py \
    --assets /path/to/HytaleAssets/Server/Item/Items \
    --out    mod/src/main/resources/Server/Item/Items \
    --textures-out mod/src/main/resources/Common/BlockTextures

Add --verify to check the shipped files are current without writing anything. The overrides are copies of the vanilla assets with two fields changed, so they need regenerating whenever Hytale updates those files.
