.mtl thumbnails Windows 10

For whatever reason all of my .mtl files in the Rhino materials library are represented by a Photoshop icon and not a preview of the material. I don’t remember having this issue last time I was using the material library to create materials. Any thoughts?

Thanks,

Hi Dennis - try TestRestoreLibraryFileAssociations. Any luck?

-Pascal

That seemed to do the trick. After running the command and restarting I just had to set all my folders to display icons again.

Thanks,
Dennis
