Thanks you all
I have modeled this thing in Maya, Export with Maya to Indigo 0.9 for rendering in Indigo 1.0.3., Thank you all for these incredible developpement

.
I'm not very happy with this images, I think it don't emphasize my model, It should be principally a bad position of the equipment (my bump is very bad too

)
I can show you some ambient occlusion images rendered with Mental Ray for well see the model (my more psychopathic one

).
