I’m trying to achieve in Blender Cycles (preferably 2.79b) a shader that fills in any object with procedural generation.

For example, if I have a model of a hand, I want to fill with vessels inside the hand. Like following inage:

Vessels in hand

My final goal is not to add vessels, but tree branches/roots. I want to make a hand look like it’s made out of tree roots. Or maybe electronic wires.

I think is the same idea, but different settings on how the inner object renders.

Here is another example, but being used in a human lung: (Apparently this was made in Houdini)

Houdini lung vessels

Can anyone lead me to the right path to achieve this. Thanks in advance.
