ExportSelection will export all geometry in the current
Selection to an .OBJ file. The file is saved to the path chosen by the user in a file save dialogue (the
filePath argument is ignored). This function does the same thing as the Export Selection… right-click menu option in the Explorer.
Previously, this function would save the generated .OBJ file to the given file path, so long as Roblox Studio had write access. This was changed for security reasons on Release 379 in April 2019.
