Which is the best lighting technique to meet Ryan’s demands?

ryan wants his play to end on a high note. he explains the final scene to his light designer and clearly tells him that in the climax scene, none of his actors can have shadows on the stage. understanding ryan's requirements, the light designer plans to implement the method by which he create six divisions on the stage and have a light for every division that will eliminate any shadows

i hope this helps :)

soft,hard and rough for soft would be a pillow or a stuffed animal hard wood floor or a table rough paint
