/**
 * Allows to edit properties of materials.
 *
 * @remarks
 *
 * Note that if the input node use a material created via a [MAT node](/docs/nodes/mat), and not when loading the geometry via a [File SOP](/docs/nodes/sop/file), it's important to keep in mind that materials are shared.
 * Therefore any other object also using those material will be affected.
