Shade files not exported or imported

[cesmith]

When exporting a project with near shadings specified (.SHD files for example), these files are not exported. If I copy the missing files explicitly to the export location and then import, the shading files are again not transferred.

The shading scene is stored within the "Calculation Version" file (*VCi).

The opportunity of saving shading scenes as *.SHD is useful for intermediate saves when elaborating a complex scene, or for reusing the scene in another project.
