bevy_fontmesh

A simple and focused Bevy plugin for generating 3D text meshes from fonts. Powered by fontmesh.

What it does

Turns the same Handle<bevy::text::Font> you already use for Bevy's 2D UI text into a 3D extruded mesh. You control extrusion depth, anchor, justification, and subdivision quality; Bevy handles materials, lighting, and rendering.

Under the hood, cosmic-text shapes the text (kerning, ligatures, BiDi, complex scripts) and fontmesh tessellates each glyph.

Quick Start

[dependencies]
bevy = "0.18"
bevy_fontmesh = "0.4"

use bevy::prelude::*;
use bevy_fontmesh::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugins(FontMeshPlugin::<StandardMaterial>::default())
        .add_systems(Startup, setup)
        .run();
}

fn setup(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
    mut materials: ResMut<Assets<StandardMaterial>>,
) {
    commands.spawn(TextMeshBundle {
        text_mesh: TextMesh {
            text: "Hello, World!".to_string(),
            font: asset_server.load("fonts/font.ttf"),
            style: TextMeshStyle {
                depth: 0.5,
                anchor: TextAnchor::Center,
                ..default()
            },
        },
        material: MeshMaterial3d(materials.add(StandardMaterial::default())),
        ..default()
    });
}

For per-character styling use [TextMeshGlyphs] / [TextMeshGlyphsBundle]; for custom materials, add the plugin a second time with your material type:

app.add_plugins(FontMeshPlugin::<MyCustomMaterial>::default())

See docs.rs/bevy_fontmesh for the full API.

Rendering both sides

The generated mesh is single-sided (front, back, and outward-facing side walls) — same shape as ttf2mesh and previous bevy_fontmesh releases. If you look through a glyph's hole (e.g. into the counter of a 'B') and want the back face to render, set:

StandardMaterial {
    double_sided: true,
    cull_mode: None,
    ..default()
}

The examples in this repo all do this.

Examples

cargo run --example basic                  # Simple 3D text
cargo run --example multiline              # Multiline with anchoring
cargo run --example justification          # Text alignment
cargo run --example anchors                # All anchor points
cargo run --example per_glyph              # Per-character styling
cargo run --release --example stress_test  # Performance test
cargo run --release --example showcase     # Metallic "BEVY" with orbiting camera
