# Unreal Materials

- `create_material_instance`

- `set_material_instance_parameters`

+ - `connect_material_expression_to_customized_uv`

- `assign_material`

+ `connect_material_expression_to_customized_uv` is the typed material-root path for

+ Customized UV 0-7. Select exactly one source output by zero-based index or exact,

+ case-sensitive output name. The native editor bridge validates graph ownership,

+ records an undo transaction, saves synchronously, and verifies the saved connection.

+ It fails closed when the package already contains unsaved changes or a different

+ connection occupies the requested input unless `replace_existing=true` is explicit.
