mental ray demo

in this demo we made a room with a glow on the window and a light that pass's though and bounces of the walls and casts shadows from the lights to make a half realistic scene. To do this we made a cube and cut 2 holes in it to make a window and then flipped the normals with the normals tool. then we added a skylight so that the whole scene was light up and mr sky portals to direct that light into the window then we made a mr spot light to add rays of light in to the window and a glow on to the sky portals to add a little realism  to the scene. we then added a camera into the inside of the room so that we could get a better render. then we started to add in textures to the scene we started with a arch and design material and added a concrete texture into the diffuse and then added a noise map into the bump channel to add the effect of holes in the concrete.
