ok now select one of your Area Lights and turn on (Emit Photons) and do the same settings or according to your scene size, Photons are scene dependent, if you have larger scene then low amount of photons won’t work until you increase them
11 - In Render Settings in the mental ray tab choose (Mitchell) for Multi-Pixel Filtering
12 -
Turn on (Final Gathering) and do the rest as you can see on the image below
13 -
With these settings set, hit render. Your result might be different then mine because I am using texture on the floor so this also cause to emit photon same as color of my floor texture
14 - Ok, Apply the textures everywhere to all of your scene and if you hit render you will see a very dark image, if you deal with darker wood textures or something like this.
As you can see in the above image the wood texture for the floor is pretty dark if I apply this texture to all room I am sure I will get pretty dark result, you might be asking why is this and what cause this heck? Well the answer is pretty simple, the texture which you are applying to the objects, the material itself has Photonic Attributes, and then the material starts emitting Photons the same color as our texture in the scene that is why we are getting darker result, to solve this problem select your material where the texture is set for the walls, and then hit CTRL+A to open attributes editor, expand the Mental Ray tab scroll down a bit uncheck (Derive From Maya) check box, and then click on (Take Settings From Maya), now if you see in the (Color) slot our texture is connected that is why its emitting dark photons, do the right click and from popup menu chose break connections and set the color to something brighter as you can see in the image below.
