3ds Max | Railclone| Vray | Marvelous Designer | Photoshop
For this render I actually had to show some more of the exterior but that was quickly done with Itoo Software's Railclone.
I created the bedding and blanket with Marvelous Designer, a cloth simulation software I have come to love.
Quick screenshot to illustrate the positioning of the sun and the skylights. The soft lighting was achieved by adjusting the size multiplier of the sun. I chose color mapping Reinhard with a burn value of 0.5
This image was rendered with a Vray standard material in the override material slot in the Vray settings in order to observe the overall lighting without the distraction of materials.
