My contribution to the Christmas Lighting Challenge,
by Jeremy Birn.
Maya 2008 with MR Physical Sky/Sun & Mia X Materials.
2 MR Portal Light, one behind the window, and one behind the door for the warm interior ambience.
The Physical Sky enviroment is connected to both Portal lights using the enviroment slot.
A Mib Blackbody with a temperature of 6500 K is connected to the Light colour slot of the window Portal Light.
A Mib Blackbody with a temperature of 3200 K is connected to the door Portal Light colour slot.
The Light emitting from the wall lamps, the Christmas Tree lights and the Fireplace, is achieved through the additional parameter of the Mia X Material, to which I connected Mib Light Surface shaders.
Finally I rendered an additional AO render pass, and another slight additional lights fog pass with software maya renderer,
and composited all in PS.
