Occlusion in dark ( OccId )

Hi all ..

the occlusion is a very important pass to add details to the image.

But there is a very beg deference between normal occlusion like the first image and occlusion in darks ONLY and this is the second image.

• Normal Occlusion
  

• Occlusion in dark

the occlusion in dark (occid) is showing the occlusion in darks according to the light and due to the Surface luminance node data.

Here is the connection...

the idea of the connection is..

we make a ramp from white to black and map it to the color of the color of the surface shader and and then i create a surface luminance and connect it to the ramp as Out value > V cord 

so the shader will look like the cartoon shader the ramp will be mapped as the direction of the light goes.

so we create a mib_amb_occlusion and connect it to the black color of the ramp and with this will are tilling maya to put the occlusion in the dark side of the object (according to the light)

an example ...
