The appearances in SOLIDWORKS Visualize are different than shaders in traditional rendering applications. All appearances in SOLIDWORKS Visualize are scientifically accurate. Less guesswork is required for you to create or edit an appearance to have the properties you want.
When you create or modify appearances, the changes are saved in the project's .SVPJ file, and the new or modified appearances are listed in the Appearance tab of the Palette. Creating or editing an appearance in the Appearance tab does not add the appearance to the Appearance library. You need to add a new or modified appearance to the Appearance library separately.
