Damon Dash
 just lost custody of the daughters he shares with ex-wife Rachel Roy, and it's probably all news to him ... since he didn't even show up for the hearing. 

Roy just got sole legal and physical custody of 15-year-old Ava and 6-year-old Tallulah. Dash also wanted full custody.

The former couple each accused the other of being an unfit parent. He claimed she drove drunk with one of the girls, and threatened to cut him with a knife. She claimed he smokes weed around the kids. She said all the women and drugs were a bad influence on their daughters.

The judge clearly sided with Rachel, ruling Dash only gets supervised visitation.

Roy also got a three-year restraining order against Dash.
