Cargo features


Enables spans, in combination with bevy's bevy/trace feature, you can generate profiling reports you can open with any trace reading software. Useful for debugging why your assets are so slow to load.


Enable handling of Maya's PBR material extension for FBX (presumebly also 3DS max). This is highly experimental and only tested with a single model! Please report if your model's materials do not load properly.

This material loader do not work with every type of texture files, the textures must be readable from CPU and have each component (color channel) be exactly 8 bits (such as PNG).


  • cube: Load simple cube with point light
  • scene_viewer: Load any FBX files from /path/to/file.fbx, defaults to assets/cube.fbx

Run example:

# Regular dev build
cargo run --example <example_name>

# Faster asset loading
cargu run --example <example_name> --release --features bevy/dynamic
