i somehow managed to mess up the file allocation for .renv environments so thumbnails are gone
is there a way to get it back?
I tried Rhino-installer->repair rhino +OS restart.
Re-Registered the Rhino thumbnail viewer(even tho .3dm thumbs where working and still are)
registering .renv files to rhino 7 which just led to a lot of rhino-heads as you can see in the pic above
ah yes and its win 10 im tralking about
