Hi Esther, You can change the material of the material zones in the Texture room, while your object is selected click the paintbrush icon in the top right of the screen. YOu now can edit the different shading domains of your selected object, don't know how Poser objects come into Carrara but this should work. To change the actual Shading domain size or shape , you would do this in the Vertex modeler by selecting the shading domain and adding to it and renaming the shading domain. Mike
