In NX2312, solid bodies are displaying glossy when shaded.
SolutionIn NX2312 the default Global Finish on the Display tab is set to Satin and this displays as glossier than previous NX versions.
You can change the appearance on shaded models on the Display tab as shown below or in the Customer Defaults by selecting 'File-> Utilities-> Customer Defaults'. Then select 'Gateway-> Visualization-> Rendering' and on the 'Style' tab at the bottom the default for 'Global Finish' can be set. It defaults to 'Satin' and can be changed to 'Matte' for a less glossy display of shaded models.
This setting has a Session specific Scope so it will apply to all parts in session.
