Struct Mesh 

pub struct Mesh {
    pub asset_id: AssetId,
    pub source: String,
    pub primitive_index: u32,
    pub chunk_index: Option<u32>,
    pub vertices: Vec<VertexData>,
    pub indices: Vec<u16>,
    pub lod_levels: u32,
    pub lod_distances: Vec<f32>,
    pub locator: Option<PayloadLocator>,
}

Raw geometry. Supply vertices and indices directly, or import them from a binary glTF file with source + primitive_index.

Use when you want full control over shape: custom furniture, architectural details, signage, or any form a generator cannot produce. For standard shapes use ProceduralMesh.

Normals and tangents are computed automatically at build time. Do not supply normals or tangents.

Vertex color: use [0.75, 0.74, 0.72] for a neutral surface that takes the material albedo, or [1, 1, 1] to pass through unmodified.

Winding: triangles must be counter-clockwise when viewed from the front. Reversed winding = invisible face.

Fields

asset_id: AssetId

Asset identity; injected via inject_name. Not part of args.

source: String

Optional path to a .glb file. When set, the build imports vertices / indices from it; inline geometry leaves this empty.

primitive_index: u32

Which primitive (counted across all meshes in the file) to import from source. Ignored when source is empty.

chunk_index: Option<u32>

Pick a single chunk of an oversized imported primitive. None (the default) imports the whole primitive, which is fine whenever its vertex count fits in 16-bit indices; larger primitives are split into chunks on import, one Mesh per chunk.

vertices: Vec<VertexData>

Vertex list. Each vertex: {"pos":[x,y,z], "color":[r,g,b], "uv":[u,v]}.

indices: Vec<u16>

Triangle index list (16-bit values).

lod_levels: u32

Number of level-of-detail versions to generate, including the original. 1 (the default) generates none; values are clamped to [1, 8].

lod_distances: Vec<f32>

Camera distances at which to switch to each lower-detail version. Length should be lod_levels - 1; empty lets the build derive a default sequence. The version for index i is used at camera distance ≥ lod_distances[i].

locator: Option<PayloadLocator>

Injected at load time from the compiled blob payload.
