Hi,This modern bedroom interior design uses natural sun lighting, not using HDRI, for internal lighting using only my lighting effects, except for lighting the room in the wardrobe (Ies Light)
The main software for this design:1.3ds max 2017
of course you can open this file with a higher version,No need to worry, I also attach / use good quality textures and bumps,hopefully you can learn about each setting in each realistic rendering setting.
