# Material LOD
When using a Pipeline object, the whole process of combining and setting up a new baked material is automatic, but when using the processing objects indivudually a series of discrete steps need to be performed in order for the output scene to be coherent.
- Process the input scene with a Processor, generating a MappingImage.
- Use the original materials and MappingImage as inputs to MaterialCasters to generate new textures.
- Setup the new material with references to the new textures in the processed scene.
