Well, I continued refining a breast morph for the P8 Low Res female. (actually it is Maria) 3 Alysons (Maria's), full texture (modified colors, and sharpened, and sharpened) in IDL took about 5 min to render. (click to full size)

The LEFT Figure:
THE SAME texture is connected to:  (BB, rest seated, it's just a KISS experiment)
There is NO other texture used, just and only the figures texture! (body + head + standard Maria eyes and laches)

Diffuse 0.8 ==>
Specular color base color white ==>
Specular value 0.25 ==>
Highlight is at 1.000, ==>
Reflection color base color white ==>
Reflection value 0.1 ==>
Bump 0.005 ==>

The Middle figure:
Diffuse 0.8 ==>
Specular color base color white ==>
Specular value 0.1 ==>
Highlight is at 1.000 ( no tex )
Reflection color base color white ==>
Reflection value 0.2 ==>
Bump 0.005 ==>

The right figure
Diffuse 0.8 ==>
Specular color base color white ==>
Specular value 0.25 ==>
Highlight is at 1.000  ( no tex )
Bump 0.005 ==>

have to reduce bump for close ups. (texture a little too scharpened, but OK for distance shots)
Anyhow, it was a morph test!

Oh, yes, before I forget:
Collars X to 102
Shoulders X to 110
Forearms X to 120

Render Settings
CShadows ON
Raytracing ON
Bounces 2
IC 10
Indirect light ON
Pixel samples 3

Rendered full screen, reduced till below 200K to put here 

But, when i try to render at IC 100, my PC is often on his / her knees...

Past 03 Am now, bedtime.
have a nice day.
