Quote - It can increase the height of those veins, but it can't make them thicker. Those veins are part of the body displacement map. The parameter Body Displacement controls the height of that. There is more to that map though, it include muscle definition and some wierd bumpiness on the neck which I don't like.

Oh yeah, did some checking and noticed that. Been looking that the Displacement image file. Too bad you can't control the vein defination without affecting the muscle defination.
