# maya-materials (Authoring stage)

Build and assign basic shader networks. Eight scripts cover the typical
"create a Lambert and assign it" loop while keeping `inputSchema`
validation in place.

`set_material_attribute` includes Maya 2022 / MtoA compatibility aliases for
Arnold `aiStandardSurface`, such as accepting `metallic` and writing
`metalness` when that is the available attribute.

`assign_material` accepts at most 256 targets and reads shading-set membership
back for every resolved object before reporting success.

For sharing material presets across assets / shots, use
`maya-material-library`.
