Struct ObjOptions 

pub struct ObjOptions {
    pub include_normals: bool,
    pub isolated: Option<Vec<u32>>,
    pub hidden: Vec<u32>,
}

Options for OBJ export.

Fields

include_normals: bool

Emit per-vertex normals (vn + f a//na). Most DCC tools expect them.

isolated: Option<Vec<u32>>

Restrict to these express ids (isolation allowlist). None ⇒ no filter, every mesh is a candidate; Some(empty) ⇒ the filter is ACTIVE and matched nothing, so every mesh is excluded. Do not collapse the two — an active isolation that matches zero elements must export nothing, not silently fall back to the whole model (matches the null-vs-empty convention used by GltfOptions::isolated and by packages/export/src/reference-collector.ts on the TS side).

hidden: Vec<u32>

Exclude these express ids (hidden in the viewer).
