The illumination of this scene is quite complex because im not using any system of global illumination I have had to emulate this with light-references distributed by the room. The main light comes from the Sun to which I have applied an Volume Light effect with density = 1,9. Then I have created an Omni with a brown color, activated attenuation and a multiplier value very low,I have made several references of that omni and there are them distributed for the scene.
I have created three spots to create to the roof lights, these give a yellowish light and they have the Inverse Square "Decay" activated, finally, I have created some more lights : One behind the photographer illuminating the whole scene frontly, another red one in the pilot over the door and another red one more behind the photographer to their right.
The render time was 0:04:39 in a resolution of 1.600 px / 840 px with an AMD K7 1400, I Made a small PostProduction in Photoshop that consisted on adding some contrast, a sharpen mask and to darken some areas.
I give thanks to 3DTotal because they have made a great job with these CDs, there is enough variety of seamless maps for any CG work with unquestionable quality, the bump maps are not just a desaturation of the diffuse map, the dirt maps are vastly useful for rustic textures, there are panoramic skies of great beauty, bricks, metals, shadows, cloth, stones... even a max library of procedurals material. I think that the quality or my work will increase with the Total Textures and they will be of much help in the future.
