can you crop your pictures so there is as little black space as possible? it's kinda weird to see this giant picture only to find that the actual image is this little thing in the center...
not sure why you want to make a person reflective, last time i checked we cant see ourselves in other people's skin
blinn shaders have a reflectivity of 0.5 by default. if you didn't change this then the material will reflect stuff
skin shaders are usually done with subsurface scattering (sss), which is where the light reaches the material, bounces around inside a bit before going back out (i think)
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
