Autohint for variable fonts

Are variable fonts autohinted?
If there are hinting instructions what happens?

Many thanks!

Last time I checked the autohinting wasn’t working well. The version in Glyphs doesn’t support hinting variable fonts.

thanks! and If there are hinting instructions is the variable font is exported with hinting?

Maybe there are manually hints in the file?

Yes. TT hints inserted with the TT instruction tool are exported into the variable font.

ok thanks
