Options controlling a repack (existing UVs → new packing, no chart computation).

Member Data Documentation

std::string_view input_chart_attribute_name

Optional per-facet chart id attribute name.

When set, each input UV island is pinned to its own chart; otherwise xatlas re-derives charts from shared UV edges.

std::string_view output_uv_attribute_name = "@uv"

Output indexed UV attribute name.

If the attribute already exists, its value type is preserved; otherwise a new attribute is created using the mesh Scalar type.

bool enable_sharing_uvs_between_instances = false

Whether to share generated UVs between instances of the same scene mesh.

When false, each scene instance is repacked independently.
