+ *
+ * By specifying a base name and an extension, Qt3DCore::QSkyboxEntity
+ * will take care of building a TextureCubeMap to be rendered at runtime. The
+ * images in the source directory should match the pattern:
+ * \b base name + * "_posx|_posy|_posz|_negx|_negy|_negz" + extension
+ *
+ * By default the extension defaults to .png.
+ *
+ * \note Please note that you shouldn't try to render skybox with an
+ * orthographic projection.
