Bevy 0.19 — Voxel data (RON, palette, KTX2 atlas)

When to use this skill

• Defining a moddable block catalog in a text format authors can edit.
• Building a runtime palette keyed by BlockId (u16/u32) for fast lookup during meshing.
• Packing per-block textures into a single atlas so all chunks can share one material.
• Switching the atlas to KTX2 for GPU-friendly compressed delivery.
• Choosing a runtime chunk storage format (flat array, RLE, palette compression, hybrid).
• Optimising procedural world generation: extremity bound checking, noise upsampling, noise caching, cross-biome noise sharing.
• Surveying the Rust/Bevy voxel-crate ecosystem and its current gaps before reaching for a dependency.

Canonical end-to-end flow

1. Define blocks in RON (assets/blocks.ron). id is the immutable, serialized identity; name is presentation text and may change:
