Contents Materials » Optical Properties » Optical Properties ManagementPrint page Optical Properties Management This section helps you manage and share materials in a same project or between projects. This section contains the following topics:Creating a Material LibraryCreating a material library consists in exporting from one to all materials present in an opened project in order to share it with other projects.Opening a Material LibraryOpening a Material Library allows you to directly display a list of materials in the Speos interface. Applying a Material from a Material LibraryThis procedure helps you apply a Volume/Surface Optical Properties material (VOP/SOP) on bodies or Face Optical Properties material (FOP) on faces from an opened material library.Applying a Material from the TreeThis procedure helps you apply a Volume/Surface Optical Properties material (VOP/SOP) on bodies or Face Optical Properties material (FOP) on faces directly from the tree.Replacing a Material on GeometriesThis procedure helps you replace a material applied on all its faces or bodies by another material.Converting Face Optical PropertiesThis procedure helps you convert an existing Face Optical Properties material (FOP) into a new FOP based on the material properties of a selected Volume/Surface Optical Properties material (VOP/SOP) while keeping the faces of the existing FOP. « Creating a VOP on SurfaceCreating a Material Library »
