XSMP Material Lab has built-in scenes for user-friendly material testing.
The scenes use the same geometry that was used to create preview images for Presets Library.
It is possible to choose the desired scene units, as well as the possibility to use the Real-World Scale units.

The STUDIO edition shows all scenes at once for all rendering engines. In the PRO edition, only scenes for a specific engine are available, e.g. scenes for V-Ray when a PRO V-Ray edition license is available.
