This model was created in cinema4d r20 and is setup to render with arnold 5. Diffuse texture and specular map and .fbx are included for use in other programs however one color correction node used on the specular to fine tune it within the regular cinema4d file. If you are using this desk in another program you may have to brighten the basic included specular map.
Lighting scene is included as modernDesk05_presentation
model 'quirks' : the planks that are slanted that are on the bottom side of the table will give off more of a reflection than the rest of the table most of the time because of their slant which may be undesirable. It is a separate object however so adjusting or turning down the fresnel or specular color is no problem.
