Lighting tutorial in Maya...

The Maya interface.
On the left of the screen is my 3D view, showing the modeled room and backplate image, of Melbourne in the sunshine!
The red lines above it, indicate a direction light which creates sun light.
I used a combination of direction and fill lights to create sunlight to spill through the window and onto the bed and the floor - as seen on the right hand image (which was the render view).

Looking forward to playing with more lights !

Another view of the same configuration, with the room rotated to show the furniture. The lighting only shows correctly in the render view.
