# Materials in USD Scenes

When working with materials in Katana in the USD space, you currently have the following options.

• You can use the UsdMaterial node to create and edit singular materials and shaders in USD. This is a limited node and would mostly be used for debugging, setting up simple shaders on things like shader balls or low-definition assets, or setting AOVs.

See Using UsdMaterial.

• While you can’t create a native USD material network and connect materials together yet (this is being worked on), for now you can create a material network in Geolib (NetworkMaterialCreate) and then convert it as USD using KatanaToUsd node. With your materials in USD, you then can use a UsdMaterialAssign node to assign these to USD Native meshes.
