And again...

... I've been working on some more models and renderings. The newest one is a model of a staircase that's going in the penthouse of a project in Chelsea our office is working on. The client wants the stair to be open and well-lit without the use of lighting fixtures. We decided to recess the handrail and since the stair width is under 40" we only need one... Inside this recessed handrail, we've added some LEDs. These along with the stair lights [small, pin-hole LEDs] are the only lighting going in the stair. With high GI settings, all I have in the space is one sky illumination volume and one sun light. There are no other lights. The renders took a while with a diffuse depth of 6 and a max ray resolution of 450. All in all, they seem pretty crisp. Take a look...
