When I import geometry in a file that already has the same material, I have the choice to keep the material in the file, overwrite it, rename the new one, etc.
But when the capitalization of the material name is different, the dialog box doesn't show and the two are visible in the material editor.
Then V-Ray seems to be confused and won't render the objects that have this material.
In some files, even if I delete the offending materials and purge unused ones, then re-import it, it doesn't work.
I managed to save a small part that shows the problem.
