If you used previous versions of VMPP, CMPP, or MRP, you can import library categories into a newly created directory.
From the context menu, select “Import Legacy Category…” and specify the path to the *.mat file of the old library category. All materials of old category, previews and comments will be automatically imported.
Unfortunately, there is no way to import the entire library at once (to avoid possible errors), so you need to import one category at a time.
Add new material
Adding material presets is easy.
Create a new directory or select existing one. Right-click the context menu item from where you want to add the material:
a) Get Material From Selected Object
b) Get Material From Slate Material Editor
c) Get Material From Compact Material Editor
Done. Materials is added to the selected directory (Category or Folder).
XSMP will automatically create a new directory for material that will contain the material file (.mat) and preview images.
