I did some tests on my scene with lighting. After I asked Alan for some help, he dpointed me to create point lights, over the whole corridor and some inside the rooms to give some ambient lighting, and apply a directional light coming from the side ( I just have to model a plane and a window to create the light shape). Also, I did some experiments with some other attributes.
1 Point Lighting in the center of the room
5 Point Lightings on the corridor
Alan, I did as you did on the Maya class but it's not looking the same, I have put the same attributes but I had to lower the number of lights, otherwise would look to bright. Also the shadows on the skirting boards look a bit weird, is it the shader? Thank you .
