Texture and render hookah

In this lesson we will start render hookah in MentalRay.
Open render setting windows and choose Mental Ray from renders list



Create Image based light:





Load HDRI image (in this example I used free HDRI Dock-Sphere-FREE.hdr )
you can download free hdri images also from http://www.debevec.org/Probes/
In Render Stats turn off Primary Visibility
Select mentalraylbl1 (light sphere) and scale down it to 100.



Now begin to make a base material, start with blinn:



Tweak this blinn as on picture
Eccentricity 0.2, Specular Roll Off 0.7, Reflectivity 0.95
At MentalRay field, Reflection Blur and Rays 60:



Create ramp, connect it to transparency of blinn and tweak it,
Type U ramp, for white color set value 0.95:





Turn on raytrace refractions, set index 1.3:



Create another blinn for upper parts of hookah:



Tweak it as shown:



And for bowl create also blin and tweak it
Eccentricity 0.2, Specular Roll Off 0.75,
Specular color just a little move to the right (Value 0.6),
Reflection Blur 20, Reflection Rays 60:



Go to Mental Ray render setting set it to Production quality
And turn on Final gather:







Create three spot light
Left intensity 0.6, right 0.4, behind hookah 1:



Look throw each spot light it's must cover hookah:



Set color gain for image based light, set value 2:



That is all, that is basic rendering with MentalRay and HDRI.
