Looks like a lonely place, a bit abandoned but not entirely, the tub is warm and cozy, and above all, fun...
First of all, I have to say that this place was very special for the author, so I first contacted him to have his approval and make it in 3D.
I really wanted to do it for a long time, and it has been a great pleasure to be able to create it. Since it was not a very large space I have tried to fill it with details and new techniques, among them it is the first time that I use Ray Tracing and I really liked the amount of life it gives to the environment.
