Two beautiful new building interiors from quality content developer Jack Tomalin, suitable for a national library or a big museum interior: Aslan Court 1 and Aslan Court 2, both of which are currently on big discounts. They work with DAZ Studio or Poser, and there are light sets for DAZ 3 and 4.x. There are also OBJ versions, which is handy.
These interiors might work well with exhibitions stands and rope barriers from the Roman Museum Hall, and… perhaps a Cthulhu statue in the centre of the dome? 😉
