Polar to rectangular conversion TOP

Hi everyone,

Maybe I’m missing something obvious, but is there a way to convert a polar image to rectangular in TD?
(i.e. to unwrap a tiny planet)

Thanks!

Replying to my own question in case that it may help someone in the future. Use a Projection TOP, fisheye to rectangular, use an FOV of 180 degrees and an X rotation of -90. After a lot of fiddling, problem solved.
