In August, Galloway said she believed "something is wrong at the heart" of Creative Scotland after being asked to re-write an acceptance text after winning the Book of the Year prize for her memoirs All Made Up, while Greig, who last night picked up an award for theatre work, has been a frequent critic of the funding body.
Galloway was awarded the Literature Award at the prize ceremony at the Kelvingrove Art Gallery and Museum in Glasgow. She did not attend.
The award ceremony saw performances from Nicola Benedetti, Mánran, and Lorne MacDougall.
The film and TV award was won by Ken Loach's The Angels' Share, the visual award was won by the late George Wyllie, the creativity in schools award was won by Fèis Rois and the new talent award was won by Paul Brannigan, star of The Angels' Share.
The creative business award was picked up by Glasgow's Oran Mor venue, and the traditional arts, Scots and Gaelic award went to Mánran.
The music award was won by Admiral Fallow and Whatever Gets You Through the Night by Cora Bissett with Swimmer One.
The community arts award was won by The Zombie Project at Renfrewshire Arts and Museums, while the Scottish arts ambassador award was won by director John Tiffany and Vicky Featherstone, artistic director of the National Theatre of Scotland, for Macbeth, The Strange Undoing of Prudencia Hart and Black Watch.
The Big Noise Concert in Raploch won the event prize.
The Creative Scotland Awards marked the end of a miserable year for Creative Scotland. The organisastion has been under almost constant attack from artists and arts companies since spring, when the axing of stable funding to more than 40 companies was announced.
