A question about realistic Skin Colours
My main character (using a MAT for Victoria 4) has medium-dark skin.  A strange thing happened after I followed a tutorial, a few weeks ago.  Her skin went from medium-dark to super dark.

Original settings
Diffuse colour: 119 78 58 (100 % strength)
Glossiness: 75 %
Specular: 0 0 0
Ambient: 0 0 0

New Settings with super dark skin
Diffuse colour: 119 78 58 (100 % strength)
Glossiness: 75 %
Specular: 51 72 77
Ambient: 0 0 0

I have a buffer of about 75 images of the woman's skin colour being medium dark (using original settings).  I really like the super dark too. I do not want to delete these 75 images.  

My question about realistic Skin Colours:  Can a person's skin change this much between a Canadian/Northern European winter and summer ?

Hair Colour
I have a strange problem all of the sudden, using Black hair MATs.  I typically have hair set to Matte.  Lately, most of my black hair is super glossy and grey.  I dont understand why.

Animating in Iray
I want to Animate in Iray, typically scenes are 5 to 15 seconds long at 30 frames/second.  So far, I cannot find the right settings that will complete the movie in a span of less than 24 to 36 hours.
