I've always considered HDRI as out side lighting and point lights as inside lighting.

None the less DAZ has proven incapable of this sort of work. Bullet is from a different company and shoehorned in. Triax weightmapping is from a different company and shoehorned in. The changes DAZ has made have amounted to changing the UI and light icons. DAZ has not added any new features that it developed it's self.
